The third option is the right one
If Vicki works 19 hours per week att $17.30 per hour, then her weekly savings is
(17.30)(19) = $328.70
So, if she needs to save at least 4 000, then she it will take her (4000/328.70) which is approximately 12.17 weeks. That means she has to save for at least 13<span> weeks. </span>
The equation can be written in vertex form as
y = a(x +2)² - 3
Substituting the given values, we can find the coefficient "a".
-5 = a(-1+2)² -3
-2 = a . . . . . . . . . add 3 and simplify
The coefficient of the squared term is -2.
Answer:
When the number of sessions is equal to 10, the total cost is the same in the two plans
Step-by-step explanation:
Let
y ---> the total cost
x ---> the number of sessions
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
Planet Fitness
we have
The slope is equal to

The y-intercept or initial value is equal to

substitute
----> equation A
Gold's Gym
we have
The slope is equal to

The y-intercept or initial value is equal to

substitute
----> equation B
Equate equation A and equation B

solve for x

therefore
When the number of sessions is equal to 10, the total cost is the same in the two plans
Sometimes because it might not always be true
