To find the y-intercept, plug in 0 for x and you solve to get 8

y=−2x+8

y=−2(0)+8

y=0+8

y=0

To find the x-intercept, plug in 0 for y and you solve to get 4

y=−2x+8

0=−2x+8

2x=8

x=0

For number 1, add the sides of the triangle. They are all given. The answer is 19.

For number 2, you use the formula for circumference, 2 times pi times radius. The answer is 43.96.

For number 3, I assume that 5 is half of one side. You would double 5 to get ten and multiply it by four, since there are four sides in a square. The answer is 40.

For number 4, you would multiply 5 times pi, but don't solve it. ( since the directions are to leave the answer in terms of pi) The answer is 5 pi.

For number 5, add all the sides together like number 1. The answer is 18.

Find the slip of every line that is parallel to the graph of the equation x-8y=-1
LenaWriter [7]

Answer:

1/8

Step-by-step explanation:

x-8y=-1

First, put the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)

-8y = -x-1

y = 1/8x +1/8

The slope is 1/8 and the y intercept is 1/8

The slope for parallel lines is the same for all parallel lines

1/8

The perimeter of a rectangle is 324 feet. the ration of the width to the length is 1:2. find the length and width of the rectang
hjlf
If the ratio of the width to the length is 1 : 2 then, we can represent their respective lengths using x and 2x.

Width = x
Length = 2x

2(x) + 2(2x) = 324
2x + 4x = 324
6x = 324
x = 54
2x = 108

The width is 54 ft. and the length is 108 feet. Hope this helps!

Will Give Brainliest<br> What Matrix Results From B+A
anastassius [24]

Answer:

Step-by-step explanation:

Matrix addition. If A and B are matrices of the same size, then they can be added. (This is similar to the restriction on adding vectors, namely, only vectors from the same space R n can be added; you cannot add a 2‐vector to a 3‐vector, for example.) If A = [aij] and B = [bij] are both m x n matrices, then their sum, C = A + B, is also an m x n matrix, and its entries are given by the formula

 

Thus, to find the entries of A + B, simply add the corresponding entries of A and B.

Example 1: Consider the following matrices:

 

Which two can be added? What is their sum?

Since only matrices of the same size can be added, only the sum F + H is defined (G cannot be added to either F or H). The sum of F and H is

Since addition of real numbers is commutative, it follows that addition of matrices (when it is defined) is also commutative; that is, for any matrices A and B of the same size, A + B will always equal B + A.
