Answer:
The answer would be 15
x = 15
Step-by-step explanation:
6x = 5x +15
Subtract 5x from both sides
x = 15
Try testing now by putting in the value
6(15) = 5(15) + 15
Distributive Property
90 = 75 + 15
Add
90 = 90
Now you know for a fact that this answer is correct.
It is three and two over three
Answer:
f(-4) = ⅑
Step-by-step explanation:
Given
f(x) = 9(3)^x
Required.
Find f(-4)
f(x) = 9(3)^x
Substitute -4 for x
f(-4) = 9(3)^(-4)
Apply laws of indices
f(-4) = 9 * 1/(3⁴)
f(-4) = 9 * (⅓)⁴
f(-4) = 9 * 1/81
f(-4) = 9/81
Simplify
f(-4) = ⅑

I have made it in above figure
