Answer:
E
Step-by-step explanation:
A linear equation is in the form of: , where m is the slope and b is the y-intercept.
m is the slope and it's given, which is -6
b is the y-intercept and it's given, which is 9
When we plug in to the form we get:
Answer:
A
Step-by-step explanation:
So we have the equation:
First, let's subtract 16 from both sides:
Now, let's divide both sides by 3:
Remember that with fractional exponents, we can move the denominator into the root position. Therefore:
Let's take the fourth root of both sides. Since we're taking an even root, make sure to have the plus-minus symbol!
Cube both sides. Since we're cubing, the plus-minus stays.
Add 4 to both sides.
