Answer

If the y-intercept and slope of two lines are the same, they are on the same precise line. To put it another way, if the two lines are the same line, the system should have an endless number of solutions.

Answer:

A: 8x +24

B: not equivalent for any value of x

Step-by-step explanation:

Part A:

The factor of 4 on the outside of parentheses multiplies each term inside:

M = 4(2x) +4(6)

M = 8x +24 . . . . . expression equivalent to M

Part B:

Expressions M and N are not equivalent for any value of x. They are equivalent if their difference is zero or can be made to be zero. Subtracting N from M, we find the difference to be ...

M -N = (8x +24) -(8x +10) = 14

There is no value of x that will make the difference of 14 become zero.

What are the values of X, Please give me an in-depth explanation so that I can answer similar problems on my own

nata0808 [166]

Step-by-step explanation:

a line is 180°

180-90 (given) = 90

so the two angles x and 2x added together equal 90

2x + x = 90

3x = 90

x = 30

the angles are 30 and 2(30)= 60
