Use properties of equality to solve these equations. identify the properties used and describe how you used them. pls 6. (–5 • 7)25 = x(7 • 25) 7. 5x = 0 8. 63 = 1x 9. 1/8x=1 10. 65 • 92 • 17 = 92 • 17 • x

10. 65 = x

9. 8 = x

8. 63 = x [it gave you the answer]

7. 0 = x

6. -5 = x

Step-by-step explanation:

#6 uses the Associative Property of Multiplication. #7 uses the Zero Product Property of Multiplication. #8 gave you the answer because x = 1x. For #9, you have to multiply ⅛ by its multiplicative inverse [reciprocal (8)] to get 1. #10 uses the Commutative Property of Multiplication.

**Associative and Commutative are the same thing, EXCEPT Commutative does NOT use grouping symbols. Associative does.

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
