Step-by-step explanation:
27^x = 9^(x - 4)
3^3x = 3^2(x - 4)
3x = 2(x - 4)
3x = 2x - 8
3x - 2x = -8
x = -8
Answer:
for the first equation
f(-3) = 34
f(4) = 6
for the 2nd equation
f(-3) = -56
f(4) ÷ 70
Step-by-step explanation:
my work is attached in a picture.
all you do is substitute each x value into each equation
Answer:
>
Step-by-step explanation:
-27/80 > -73/80
If you make a number line they are both in the negatives. If they are both in the negatives then whatever one is closer to 0 is greater.
Answer:
See explanation, and ask for more details if unclear!
Step-by-step explanation:
The perfect square of this equation is , since the square would be . 1/4=4/16, meaning that you can set up the equation in the following way:
Take the square root of both sides:
Add 1/2 to both sides:

Okay, so we know that on Friday there were 120 cars in the parking lot out of 200.
That's 120/200.
We need to simplify that to make the denominator 100 so we'll divide both the numerator and denominator by 2.
This leaves us with 60/100
Which converts into 60%
