Answer:
The slope is 50, which is the cost per month of the gym membership, and 79.50 is the y intercept. It represents the initial cost to join the gym.
Step-by-step explanation:
C(m)= 50m + 79.50,
This is written in the form y= mx+b where m is the slope and b is the y intercept.
The slope is 50, which is the cost per month of the gym membership, and 79.50 is the y intercept. It represents the initial cost to join the gym.
Answer:
Danalya napped 1 7/20 hours.
Step-by-step explanation:
Rewriting our equation with parts separated
=3+3/4−2−2/5
Solving the whole number parts
3−2=1
Solving the fraction parts
3/4−2/5=?
Find the LCD of 3/4 and 2/5 and rewrite to solve with the equivalent fractions.
LCD = 20
15/20−8/20= 7/20
Combining the whole and fraction parts
1+7/20= 1 7/20

Use the formula of the present value of an annuity ordinary which is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value 5500
PMT monthly payment?
R interest rate 0.115
K compounded monthly 12
N time 5years
Solve the formula for PMT
PMT=Pv÷ [(1-(1+r/k)^(-kn))÷(r/k)]
PMT=5,500÷((1−(1+0.115÷12)^(
−12×5))÷(0.115÷12))
=120.95
So the answer is C

Answer:
n = 7
n = -3
Step-by-step explanation:
4n+6 = n²-15
4n = n² - 21
n² - 4n - 21 = 0
(n-7)(n+3) = 0
n = 7
n = -3
