Use the distributive property to expand the following expression: -4(2a + 6b - 7)
i need help with this question

-8a - 24b + 28

Step-by-step explanation:

When you distribute, you multiply each number inside of the parentheses by the number outside of the parentheses.

Distribute:

-4(2a + 6b - 7)

-4(2a) -4(6b) -4(-7)

Multiply:

-4(2a) -4(6b) -4(-7)

-8a - 24b + 28

That's it! Hope this helps :)

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
