To write this equation in slope-intercept form, y = mx + b, we need to find m and b.
m, the slope, is the distance between the points' corresponding y-value divided by the distance between the points' corresponding x-value.
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{6+6}{-7+3}\\m=\frac{12}{-4}\\m=-\frac{12}4\\m=-\frac13[/tex]
b, the y-intercept, is shown as -5, but we can solve for it as well when it is not so easy to tell the value of b. We can solve for b by substituting known solutions of x and y after we find m.
[tex]y=mx+b\\-7=-\frac136+b\\-7=-2+b\\-7+2=-2+2+b\\b=-5[/tex]
So,
[tex]y=-\frac13x-5[/tex]

we have three rectangles triangles,so
Let
triangle STR and triangle RTQ
so,
a) for triangle STR
let
[tex]\begin{gathered} \text{ hypotenuse: RS} \\ \text{adjacent side;RT}=x \\ \text{opposite side:ST=9} \\ \text{angle:m}\angle R \end{gathered}[/tex]so, we can use the Pythagorean theorem,it states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)
so
[tex]\begin{gathered} (RS)^2=(ST)^2+(RT)^2 \\ (RS)^2=(9)^2+(x)^2\rightarrow equation(1) \end{gathered}[/tex]b) for triangle RTQ
[tex]\begin{gathered} \text{ hypotenuse: RQ} \\ \text{adjacent side;TQ}=16 \\ \text{opposite side:RT=x} \\ \text{angle:m}\angle Q \end{gathered}[/tex]again, let's use the P.T.
[tex]\begin{gathered} (RQ)^2=(RT)^2+(TQ)^2 \\ (RQ)^2=(x)^2+(16)^2\Rightarrow\text{equation}(2) \end{gathered}[/tex]c)
we know the triangles STR and SQR are similar, so
[tex]m\angle R=m\angle Q[/tex]also,
[tex]\begin{gathered} \tan m\angle R=\tan m\angle Q \\ \frac{oppositeside_R}{\text{adjacent sideR}}=\frac{oppositeside_Q}{\text{adjacent sideQ}} \\ \frac{9}{x}=\frac{SR}{RQ}\rightarrow equation\text{ (3)} \end{gathered}[/tex]finally, we can set a new equation with triangle SQR

[tex]\begin{gathered} (SQ)^2=(SR)^2+(RQ)^2 \\ \text{replace} \\ (9+16)^2=(SR)^2+(RQ)^2 \\ (25)^2=(SR)^2+(RQ)^2\rightarrow equation(4) \end{gathered}[/tex]Step 2
solve the equations
[tex]\begin{gathered} (RS)^2=(9)^2+(x)^2\rightarrow equation(1) \\ (RQ)^2=(x)^2+(16)^2\Rightarrow\text{equation}(2) \\ \frac{9}{x}=\frac{SR}{RQ}\rightarrow equation\text{ (3)} \\ (25)^2=(SR)^2+(RQ)^2\rightarrow equation(4) \end{gathered}[/tex]solution:

[tex]\begin{gathered} (25)^2=(RS)^2+(RQ)^2\rightarrow equation(4) \\ (RS)^2=(RQ)^2-175\rightarrow equation(5) \\ replce\text{ eq(5) into equation (4)} \\ (25)^2=(RS)^2+(RQ)^2\rightarrow equation(4) \\ so \\ (25)^2=(RQ)^2-175+(RQ)^2 \\ 625+175=(RQ)^2+(RQ)^2 \\ 800=2(RQ)^2 \\ \mleft(RQ\mright)^2=\frac{800}{2} \\ (RQ)^2=400 \\ RQ=20 \end{gathered}[/tex]so
RQ=20
now, replace in equation (5) to find RS
[tex]\begin{gathered} (RS)^2=(RQ)^2-175\rightarrow equation(5) \\ (RS)^2=(20)^2-175 \\ (RS)^2=225 \\ RS=\sqrt[]{225} \\ RS=15 \end{gathered}[/tex]RS=15
finally, replace RS in equation (1) to find x
[tex]\begin{gathered} (RS)^2=(9)^2+(x)^2\rightarrow equation(1) \\ (15)^2=(9)^2+(x)^2 \\ 225-81=x^2 \\ 144=x^2 \\ \sqrt[]{144}=\sqrt[]{x^2} \\ 12=x \end{gathered}[/tex]therefore, the answer is

Answer:
Explanation:
Based on the given figure, the two angles ( 54° and x) are supplementary.
So, they add up to 180°.
54 + x =180
We subtract 54 from 180 to get the value of x:
x=180-54
Calculate
x= 126°
Therefore, the value of x is 126°.

Velasquez, Miguel, Juan, and Pablo score a total of 36 points in a game of basketball. They score a consecutive even number of points from smallest to greatest in respect to the order of the names mentioned. How many points does Juan score?A6 pointsB12 pointsC8 pointsD10 points
Answers
Take into account that the scores are three even consecutive numbers. Being x a missing value we can write:
2x, 2(x+1), 2(x+2), 2(x+3)
where each of the previous expressions corresponds to the score of Velasquez, Migule, Juan and Pablo respectivelly.
Now, due to the sum of all scores are 36 point, we can write:
2x + 2(x+1) + 2(x+2) + 2(x+3) = 36
By applying distribution property left side and by ordering like terms we get:
2x + 2x + 2x + 2x + 2 + 4 + 6 = 36
8x + 12 = 36
Now, by subtracting 12 both sides, simplifying and dividing by 8 we obtain:
8x = 36 - 12
8x = 24
x = 24/8
x = 3
Then, we can replace the previous value into the expression which represents Juan score:
2(x + 2) = 2(3 + 2) = 2(5) = 10
Hence, Juan scored 10 points (option D)
Find the coordinates of the midpoint of HX1H4-1X34324
Answers
We need to find the midpoint of a segment HX given the endpoints:
H = (4.5, -4.25) and X = (3.25, -2.75)
where we have written the coordinates (initially in mixed number form) in decimal form for ease of handling operations.
4 1/2 = 4.5
-4 1/4 = -4.25
etc.
Now we apply the formula for the midpoint (in the x and y coordinates separately):
x coordinate of midpoint = (4.5 - 3.25)/2 + 3.25 = 3.875
y coordinate of midpoint = (-2.75 - (-4.25))/2 + (-4.25) = -3.5
So we can write the coordinates of themidpoint as:
(3.875, -3.5) or in mixed number form as: (3 7/8, -3 1/2)

B. All rational numbers can be written as integers.
C. All irrational numbers can be written as integers.
D. All real numbers are either rational or irrational.
Answers
Answer:
D. All real numbers are either rational or irrational.
Step-by-step explanation:
You want to know the true statement about the sets of rational, irrational, integer, and whole numbers.
Rational numbersA rational number is one that can be written as the ratio of two integers. All integers and whole numbers are rational, but not all rational numbers are integers.
3 = 3/1 . . . . an integer that is written as a rational number
1/2 . . . . . . . a rational number that is not an integer
Irrational numbersAn irrational number is a number that cannot be written as a ratio of two integers. √2 is an example of an irrational number. Its decimal representation has a fractional part that is never-ending and never-repeating.
The decimal part of any real number either terminates, repeats, or neither. If the number terminates or repeats, it is a rational number. If it doesn't, then it is an irrational number.
D. All real numbers are either rational or irrational.

A committee has raised $230 in fundraising and continues toraise 30 dollars at each event they throw.-- Identify your independent and dependent variables- Write an equation to model the situationDetermine how much money will be raised after 10 events!Answer here:
Answers
Let's denote by x = the number of events.
and let's denote by y = the dollars raised.
Because the dollars raised to depend on the number of events, we can say that the dependent variable is y, and the independent variable is x. Now, we have the following data:
first event: 1, and the dollars raised is 230. That is, our first point is:
[tex](x_0,y_0)\text{ = ( 1,230 )}[/tex]second event: 2, and the dollars raised is 230 + 30. That is, our second point is
[tex](x_1,y_1_{\text{ }})=(2,230+30)=(2,260)_{}[/tex]Now, let's calculate the slope of the graph:
[tex]m\text{ = }\frac{y_1-y_0}{x_1-x_0}=\frac{260-230}{2-1}_{}_{}_{}[/tex]that is equivalent to say:
[tex]m\text{ = }\frac{260-230}{2-1}\text{ = }\frac{30}{2}\text{ = 15}[/tex]The equation for a line is y = mx + b. Now, let's calculate b
y = mx + b
so
b = y- mx
but m = 15, so the previous equation is equivalent:
b = y - 15x
if we choose the point (x,y) =(1,230) and we replace it in the previous equation we have:
b = 230- 15(1) = 230 - 15 = 215.
So, our equation of the line is :
y = 15x + 215
if x = 10 events we have :
y = 15(10) + 215 = 365 dollars
then, to the question: how much money will be raised after 10 events?, the answer is 365 dollars.

To pay for a 15,300 car, Tony made a down payment of $3900 and took out a loan for the rest. On the loan , he paid monthly payment payment of $252.34 for 4 years.A:what was the total amount Tony end up paying for the car.(including the down payment and monthly payment.B: how much interest did Tony pay on the loan.
Answers
Down Payment = 3900
Loan Amount - 15,300 - 3900 = $11,400
Total Paid on Loan = $252.34 (monthly) for 4 years (4 x 12 = 48 months).
So, he paid
[tex]252.34\times48=\$12,112.32[/tex]So, total amount Tony paid for the car is "downpayment (3900) + loan amount with interest (12,112.32)".
So,
[tex]3900+12,112.32=\$16,012.32[/tex]Answer: $16,012.32
B)The interest is the excess amount on the loan.
Loan amount = $11,400
Loan + Interest amount = $12,112.32
Thus, the interest amount is 12,112.32 - 11,400 = $712.32

[tex]A=h\cdot b[/tex]If you know the area and the height of the parallelogram you can determine the length of the base. To do so, you have to divide the area by the height:
[tex]b=\frac{A}{h}[/tex]We know that the area of the window is A=31ft² and the height is h=33ft, you can calculate the length of the base as follows:
