To find the equation of the line we need a point and the slope. We have the point but we need to find the slope, to do this we need to remember that two lines are perpendicular if and only if their slopes fullfils:
[tex]m_1m_2=-1[/tex]Now, the slope of the line given is -6, this comes from the fact that the line is written in the form y=mx+b, hence comparing both equation we conclude that.
Pluggin this value into the condition above we have:
[tex]\begin{gathered} -6m_1=-1 \\ m_1=\frac{-1}{-6} \\ m_1=\frac{1}{6} \end{gathered}[/tex]Therefore the slope of the line we are looking for is 1/6. The equation of a line is given as:
[tex]y-y_1=m(x-x_1)[/tex]Plugging the values of the slope and the point we have:
[tex]\begin{gathered} y-0=\frac{1}{6}(x-0) \\ y=\frac{1}{6}x \end{gathered}[/tex]Therefore the equation we are looking for is:
[tex]y=\frac{1}{6}x[/tex]what is 1/5 turned into a percent
What is the slope of the line descrbed by the equation below?
The given equation of the line is:
[tex]y-5=-3(x-17)[/tex]It is required to determine the slope of the line.
Recall that the point-slope form of the equation of a line is given as:
[tex]y-b=m(x-a)[/tex]Where m is the slope of the line and it passes through the point (a,b).
Notice that the given equation is in the point-slope form.
Notice that the slope is m=-3.
The answer is option A.

Which ratio is equivalent? 8 cm to 20 mm
Given the ratio:
8 cm to 20 mm
first convert from cm to mm
1 cm = 10 mm
so, 8 cm = 8 * 10 mm = 80 mm
so, the ratio will be :
8 cm to 20 mm = 80 mm to 20 mm =
[tex]\frac{80\operatorname{mm}}{20\operatorname{mm}}=\frac{80}{20}=\frac{8}{2}=\frac{4}{1}=4\colon1[/tex]so, the answer is: 8 cm to 20 mm = 4 : 1

Edge 2023 ✅A jar contains 10 purple marbles, 2 red marbles, and 5 blue marbles. What is the probability thatrandomly chosen marble is purple? Round the answer to the nearest hundredth of a percent.
EXPLANATION
Let's see the facts:
purple marbles = 10
red marbles = 2
blue marbles = 5
The probability formula is:
[tex]P(X)\text{ = }\frac{n\nu mber\text{ of favourable outcomes}}{\text{Total number of outcomes}}[/tex]The totl number of outcomes is 10+2+5 = 17 marbles
The number of favourable outcomes is equal to 10 because there are 10 purple marbles.
Then, the probability would be:
[tex]P(X)=\frac{10}{17}=\text{ 0.59}[/tex]Probability is 0.5882352941-->0.59 Rounded to the nearest hunderdth--------------->59%.

Seven years ago, Tom bought a house for $80,000, whichappreciated in value at 9% per year due to inflation. If Tomhas 48 more monthly payments of $500 to make to the bankon his 12% mortgage, find his present equity in the house.
The equity will be the value of the house today minus the present value of the remaining mortgage payments.
We can start with the value of the house. If the house was originally valued in $80,000 and appreciated at 9% per year during 7 seven years, we can calculate the present value as:
[tex]\begin{gathered} PV=80000\cdot(1+0.09)^7 \\ PV=80000\cdot1.09^7 \\ PV\approx80000\cdot1.828 \\ PV\approx146243.13 \end{gathered}[/tex]Now we can calculate the present value of the mortgage payments as an annuity.
The payments are monthly (m = 12), with an annual rate of 12% (r = 0.12). The amount paid monthly is $500 and there are 48 remaining payments (m*t = 48), so we can calculate the annuity as:
[tex]\begin{gathered} PV=M\cdot\frac{1-(1+\frac{r}{m})^{-m\cdot t}}{\frac{r}{m}} \\ PV=500\cdot\frac{1-(1+\frac{0.12}{12})^{-48}}{\frac{0.12}{12}} \\ PV=500\cdot\frac{1-(1.01)^{-48}}{0.01} \\ PV\approx500\cdot\frac{1-0.62026}{0.01} \\ PV\approx500\cdot\frac{0.37974}{0.01} \\ PV\approx500\cdot37.974 \\ PV\approx18986.98 \end{gathered}[/tex]Then, if we substract the mortgage present value from the present value of the house, we get the equity:
[tex]\begin{gathered} E=PV_{h\text{ouse}}-PV_{\text{mortgage}} \\ E=146243.13-18986.98 \\ E=127256.15 \end{gathered}[/tex]Answer: the present equity in the house is $127,256.15
i need help: question = Which process will create a figure that is congruent to the figure shown?
Solution
Option A
Option A is Congruent because the size of the image is not tampered with, we only rotate, reflect and translate
Option A is correct
Option B
Option B is not congruent because there is a translation of scale factor of 1/2
Option C
Option C is not congruent because the distance between each points and the x-axis are tripled
Option D
Option D is not also congruent because the distance between each points and the x-axis are doubled
Hence, Option A is correct
Karla says 4 and 4.7 would fall between V17 and 4O FactO Fib
First of all, we have to know the equivalent decimal number to each of them.
[tex]\begin{gathered} 4\frac{2}{3}=\frac{4\cdot3+2}{3}=\frac{12+2}{3}=\frac{14}{3}=4.66666\ldots \\ 4.7 \\ \sqrt[]{17}=4.12310\ldots \\ 4\frac{3}{4}=\frac{4\cdot4+3}{4}=\frac{16+3}{4}=\frac{19}{4}=4.75 \end{gathered}[/tex]Notice that the interval is from 4.12310... to 4.75.
You can observe that 4.7 falls into this interval, and 4.666... also falls into this interval.
Therefore, the numbers Karla indicated fall into the interval she mentioned.The answer is Fact.Bonnie is making a dipping sauce. She mixes 150 ml of soy sauce with 100 ml of vinegar.how much soy sauce does Bonnie mixed with every 1 milliliter of vinegar
The question is asking how much soy sauce Bonnie is mixing per every millilter of vinegar. To calculate this ratio, we simply divide the amount of soy sauce she mixed by the total amount of vinegar she used. This leads to
[tex]\frac{150\text{ (soy sauce)}}{100\text{ (vinegar)}}[/tex]which is equals to
[tex]\frac{150}{100}=\frac{30\cdot5}{20\cdot5}=\frac{30}{20}=\frac{3}{2}=1.5[/tex]so Bonnie uses 1.5 ml of soy sauce per every ml of vinegar
factor the expression 120 + 50 using gcf
The given expression is,
[tex]120+50[/tex]The factors of 120 are, 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
The factors of 50 are, 1, 2, 5, 10, 25, 50
From this, we can infer that, the greatest common factor of 120 and 50 is,
10.
Therefore, we can write,
[tex]120+50=(10\times12)+(10\times5)=10(12+5)=10\times17=170[/tex]Use the vertex and intercept to sketch the graph of the quadratic function.
The expression we have is:
[tex]f(x)=9-(x+3)^2[/tex]We need to compare this expression with the Vertex form of the quadratic equation:
[tex]f(x)=a(x-h)^2+k[/tex]Where the vertex is at (h,k).
We rewrite our expression as follows:
[tex]f(x)=-(x-(-3))^2+9[/tex]And we can see that h=-3, and k=9. Thus, the vertex of this quadratic function is at:
[tex](-3,9)[/tex]Also, since we have a negative sign along side the x, that means that the parabola opens down.
And the correct result is:

Find the unknown value in the proportion. Round to the nearest tenth if needed. 4/3=12/?
Starting with the proportion:
[tex]\frac{12}{?}[/tex]Since it should be equal to 4/3, notice that if we divide both numerator and denominator by 3, then we should get 4 and 3 respectively:
[tex]\frac{12}{?}=\frac{12\div3}{?\div3}=\frac{4}{?\div3}=\frac{4}{3}[/tex]Therefore, ?÷3 is equal to 3.
Which number is equal to 3 when we divide it by 3?
That number is 9. 9÷3=3
Therefore, ?=9.
u want to construct an open-top box that is 6 inches deep, with a square base. it must have a volume of 864 cubic inches. You have one big piece of cardboard. You will start by cutting it down to a square, and then you will cut smaller squares out of each corner and fold up the sides.
Let's analyse each sentence:
A)
This sentence is true, because the volume of the box is given and it is 864 in³.
B)
This sentence is false, because the height of the box is given and it is 6 inches.
C)
Let's calculate the sides of the base, knowing that the length and width are the same:
[tex]\begin{gathered} V=\text{lwh} \\ 864=l\cdot l\cdot6 \\ l^2=\frac{864}{6} \\ l^2=144 \\ l=^{}12 \end{gathered}[/tex]The side of the cardboard will include the length of the base and two times the height, since it will be folded later on, so we have:
[tex]\text{cardboard side}=l+2h=12+6\cdot2=24[/tex]So the side of the cardboard needs to be 24 inches, so this sentence is false.
D)
This sentence is false, because the height is not equal the length and width.
E)
This sentence is true, because using the variable x to represent the side of the square base (that is, the length and the width), we have:
[tex]\begin{gathered} V=l\cdot w\cdot h \\ V=6x^2=864 \end{gathered}[/tex]So the correct statements are A and E.

Find three consecutive odd integers that add to - 99
We will investigate how three consecutive odd numbers add up to a certain value.
We will assign a variable to the first odd number as follows:
[tex]1st\text{ : x}[/tex]The next consecutive odd number will occur two integers ahead or two integers before the first odd number. We can choose either ( ahead or before ) and express second consecutive odd number in terms of first odd number as follows:
[tex]2nd\colon\text{ ( x + 2 ) OR ( x - 2 )}[/tex]Similarly, the next consecutive odd number will occcur two integers ahead or two integer before the second odd number OR four integers ahead of for integers before the first odd number. We can choose either ( ahead or before ) and express the third consecutive odd number in terms of first or second odd number as follows:
[tex]3rd\colon\text{ ( x + 4 ) OR ( x - 4 )}[/tex]We will now sum up all three consecutive odd numbers and equate the result to ( -99 ) as follows:
[tex]\begin{gathered} (\text{ x ) + ( x + 2 ) + ( x + 4 ) = -99} \\ OR \\ (\text{ x ) + ( x - 2 ) + ( x - 4 ) = -99} \end{gathered}[/tex]Then we will solve both possibilities step by step.
[tex]\begin{gathered} 3x\text{ + 6 = -99} \\ OR \\ 3x\text{ - 6 = -99} \\ \end{gathered}[/tex]Then,
[tex]\begin{gathered} 3x\text{ = -105} \\ OR \\ 3x\text{ = -93} \end{gathered}[/tex]Next,
[tex]\begin{gathered} x\text{ = }\frac{-105}{3}\text{ = -35} \\ \\ OR \\ \\ x\text{ = }\frac{-93}{3}\text{ = -31 } \end{gathered}[/tex]For each possibilitiy the three consecutive odd numbers would be:
[tex]\begin{gathered} x\text{ = -35 , x + 2 = -33 , x + 4 = -31} \\ OR \\ x\text{ = -31 , x - 2 = -33 , x - 4 = -35} \end{gathered}[/tex]We see that both possibilities result in identical three consecutive odd numbers that would add up to a total of ( -99 ). Therefore, the three consecutive odd numbers are:
