Answer:
-5 =x
Step-by-step explanation:
3^(x-1) = 9^(x+2)
Replace 9 with 3^2
3^(x-1) = 3^2^(x+2)
We know that a power to a power means the powers are multiplied
a^b^c = a^(b*c)
3^(x-1) = 3^(2x+2)
When the bases are the same, the powers have to be the same
x-1 = 2x+4
Subtract x from each side
x-x-1 =2x-x+4
-1 =x+4
Subtract 4 from each side
-1-4 =x+4-4
-1-4 = x
-5 =x

Hey there! :)
Please keep in mind that slope-intercept form is : y=mx+b ; where m=slope, b=y-intercept
Using this, we can isolate y in our original given equation.
12x - y = 4
Start off by subtracting 12x from both sides.
-y = -12x + 4
Divide both sides by -1.
-y ÷ -1 = (-12x + 4) ÷ -1
Simplify!
y = 12x - 4
Therefore, using the slope-intercept form, we can come to the conclusion that because 12 is located in the "m" slot and "m=slope" then 12 is our slope. In addition, -4 is our y-intercept because it is located on the y position.
Slope = 12
Y-intercept = -4
