Hello, I have a question with my algebra homework. we started learning about finding slope on a graph. last year I did this but they gave 2 points to find it from. how do you find slope on a line when there is no labled points. I will attach the assignment so you can better understand what I need help with.Thanks,Hunter

Riley has 200 stands 35% are from Europe 10% from Asia and 20% are from Australia the rest of the stamps are from North America how many of rileys stamps are from North America
Answers
Explanation:
First, we need to calculate the rest of the percentage. So, if the total percentage is 100%, the percentage that corresponds to North America can be calculated as:
100% - (35% + 10% + 20%)
100% - (65%)
35%
So, 35% of the stands are from North America.

two numbers have a sum of -10 and a difference of -2 what is the product of numbers
Answers
let 'x' and 'y' be two numbers that have a sum of -10 and a difference of -2, then, we have the following system of equations:
[tex]\begin{gathered} x+y=-10 \\ x-y=-2 \end{gathered}[/tex]notice that if we add both equations at the same time, we get:
[tex]\begin{gathered} x+y=-10 \\ x-y=-2 \\ --------- \\ 2x=-12 \\ \Rightarrow x=\frac{-12}{2}=-6 \\ x=-6 \end{gathered}[/tex]now that we have that x = -6, we can find the value of y substituting x = -6 on any equation:
[tex]\begin{gathered} -6+y=-10 \\ \Rightarrow y=-10+6=-4 \\ y=-4 \end{gathered}[/tex]therefore, x = -6 and y = -4. Next, we have that the product is (-6)(-4) = 24

Answers
Answer:
The line containing points A and B lies entirely in plane T.
Line z intersects plane S at point C.
Planes R and T intersect at line y.
Step-by-step explanation:
draw a sketch (see picture)
Plane S contains points B and E. - can't be true - there is no point E
The line containing points A and B lies entirely in plane T. - since lines x and y are both on plane T, and points B and A lie on x and y respectively
Line v intersects lines x and y at the same point. - can only be true IF points A and B are the same point
Line z intersects plane S at point C. - given
Planes R and T intersect at line y. - given
Answer:

Line z intersects plane S at point C.
Planes R and T intersect at line y.
Step-by-step explanation:
Note: The given diagram does not match the description. Please see the attachment for the correct diagram.
Planes
A plane is a flat, two-dimensional surface that extends into infinity.
A plane can be named by the letters naming three non-collinear points in the plane or by an uppercase script letter.
Parallel planes are planes that never intersect. Intersecting planes are not parallel and always intersect along a line.Statement 1
Plane S contains points B and E.
This statement is untrue, since point E is contained in Plane R and point B is contained in Plane S.
Statement 2
The line containing points A and B lies entirely in plane T.
This statement is true.
Statement 3
Line v intersects lines x and y at the same point.
This statement is untrue since lines x and y are on different planes.
Statement 4
Line z intersects plane S at point C.
This statement is true.
Statement 5
Planes R and T intersect at line y.
This statement is true.

Given the original triangle and the scale triangle, you can determine that they are similar.
• Therefore, you can find the scale factor by dividing the lengths of the corresponding sides given in the exercise:
[tex]\begin{gathered} sf=\frac{42\operatorname{cm}}{7cm} \\ \\ sf=6 \end{gathered}[/tex]• In order to find the value of "x", you need to multiply the corresponding side (whose length is 3 centimeters) by the scale factor:

- Scale factor:

Answers
The given division can be expressed mathematically as:
[tex]\frac{6.4}{0.02}[/tex]Emma did 64/2 and got 32 because he multiplied the numerator by 10 and the denominator by 100. This is a mistake because both the numerator and the denominator should be multiplied by equal number.
Emma can correct this mistake by multiplying the numerator (6.4) and the denominator(0.02) by 100 as shown below
[tex]\begin{gathered} \frac{6.4\times100}{0.02\times100} \\ =\text{ }\frac{640}{2} \\ =\text{ 320} \end{gathered}[/tex]Therefore, the correct result for 6.4 divided by 0.02 is 320 and not 32 that Emma got.

Step-by-step explanation:
If you draw a straight vertically and the line goes through two point then its not a function. Just look what makes a function or answer again if you are confused.
The relation which is a function is f ( x ) = x³
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
y = x³ be equation (1)
Now , relation is a function if and only if there exists one value in the range for every domain value.
So , when x = { 1 , 2 , 3 , 4 }
The values of y are = { 1 , 8 , 27 , 64 }
Hence , the function is y = x³ and the graph is plotted

At the rodeo, the bronco riding event takes place in a large dirt ring which has a diameter of 14 yards. What is the ring's radius?
Answers
The ring's radius is 7 yards.
Diameter = 14 yd.
The diameter can be defined as:
It is the length of the line passing through the center that touches two points on the edge of the circle.
Also, diameter is double of the radius
That is:
Diameter = 2 times the radius
Diameter = 2 × radius
Let the radius be r
14 = 2 × r
2 r = 14
Divide both the sides by 2:
2 r / 2 = 14 / 2
r = 7 yards.
Therefore, we get that, the radius of the ring will be 7 yards.

Suppose that when your friend was born, your friend's parents deposited $9000 in an account paying %6.6 interest compounded . What will the account balance be after 13 years
Answers
We are given the following information
Deposited amount = P = $9000
Interest rate = r = 6.6% = 0.066
Compounding interval = n = quarterly = 4
Number of years = t = 13
We are asked to find the accumulated amount (or ending balance)
Recall that the compound interest formula is given by
[tex]A=P(1+\frac{r}{n})^{n\cdot t}[/tex]Where
A = Accumulated amount (or ending balance)
P = Deposit amount
r = Interest rate in decimal
n = Number of compounding in a year
t = Number of years
Now let us substitute the given values into the above formula
[tex]\begin{gathered} A=P(1+\frac{r}{n})^{n\cdot t} \\ A=9000\cdot(1+\frac{0.066}{4})^{4\cdot13} \\ A=9000\cdot(1+0.0165)^{52} \\ A=9000\cdot(1.0165)^{52} \\ A=\$21077.85 \end{gathered}[/tex]Therefore, after 13 years, the account balance will be $21077.85
