Step-by-step explanation:
" Rachel must pay a $20 membership fee to join the gym " can be interpreted from the y-intercept of the function ⇒ D
Step-by-step explanation:
The form of the linear function is f(x) = mx + b, where
- m is the slope (rate of change) of the function
- b is the y-intercept (initial amount) of the function
∵ f(x) = 37 x + 20 models the total cost for Rachel to be a member
at a gym for x months
∵ f(x) = m x + b
∴ m = 37 and b = 20
∵ m represents the rate of change
- That means she must to pay 37 per month for x months
∴ Rachel must pay $37 per month to use the gym
∵ b represents the initial amount
- That means she pays a fixed amount one time
∴ Rachel must pay a $20 membership fee to join the gym
" Rachel must pay a $20 membership fee to join the gym " can be interpreted from the y-intercept of the function

Answer:
first, subtract 17 on both sides: x²+2x-16=0
this cannot be factored, so use the quadratic formula to solve for x:
b²-4ac=2²-4(10(-16)=4+64=68
√68=2√17
so x=(-2+2√17)/2 or x=(-2-2√17)/2
x=-1+√17 or x=-1-√17

Answer:
x^15
Step-by-step explanation:
x^3 * x^2 (x^3)^2 x^6
-------------------------------
x^2
First I will use the power of powers x^a^b = x^(a*b)
x^3 * x^2 x^(3*2) x^6
-------------------------------
x^2
x^3 * x^2 x^(6) x^6
-------------------------------
x^2
Next we will use the multiplication rule x^a * x^b = x^(a+b)
x^(3 +2+6+6)
-------------------------------
x^2
x^(17)
-------------------------------
x^2
Next we will use quotient rule x^a / x^b = x^(a-b)
x^(17 -2)
x^15
So Sally gets payed <span>$32,448 a year and gets paid the same amount each week. To figure how much she gets payed a week, divide her salary by 52 weeks since there are 52 weeks in a year. Then we divide how much she makes a week by 40 to see how much she gets payed an hour since she works 40 hours each week:
</span><span>32,448/52 = 624
624/40 = 15.6
Sally makes $15.60 an hour.
