the opposite of exponents is square root it
Answer:
x=4 and y=−2
Step-by-step explanation:
y=−3x+10;y=−2x+6
Step: Solve y=−3x+10for y:
Step: Substitute−3x+10foryiny=−2x+6:
y=−2x+6
−3x+10=−2x+6
−3x+10+2x=−2x+6+2x(Add 2x to both sides)
−x+10=6
−x+10+−10=6+−10(Add -10 to both sides)
−x=−4
-x/-1 = -4/-1 (Divide both sides by -1)
x=4
Step: Substitute4forxiny=−3x+10:
y=−3x+10
y=(−3)(4)+10
y=−2(Simplify both sides of the equation)
Answer:
I would go with c.

Answer: 
Step-by-step explanation:
You know that Mr. Wilson uses the following equation to find the cost:

Then, if Mr. Wilson spent $30, you can follow these steps in order to calculate how many hours he parked in the parking garage:
1. You need to substitute
into the given equation:

2. Now, you must solve for "H":

Therefore, based on the result, you can conclude that Mr. Wilson parked his car in the parking garage for 8 hours.
