Answer:
All real values, (-∞, ∞)
Step-by-step explanation:
<u>Step 1: Distribute</u>
5y + (86 - y) = 86 + 4y
5y + 86 - y = 86 + 4y
<u>Step 2: Combine like terms</u>
5y + 86 - y = 86 + 4y
4y + 86 = 86 + 4y
<u>Step 3: Subtract 4y from both sides</u>
4y + 86 - 4y = 86 + 4y - 4y
86 = 86
<u>Step 4: Subtract 86 from both sides</u>
0 = 0
Answer: All real values, (-∞, ∞)
F(x) = (x - 3)(x - 7)
expanding the brackets gives:
f(x) = x^2 - 10x + 21
To find the best deal find the unit rate.
City express unit rate for pants per dollars is 1 pair : $20.33
Denim Planet unit rate is 1 pair : $36.50
New Threads Unit rate is 1 pair : $27.50
So City Express is the best deal
Area of Rectangle: 64
Area of two semi circles: 12.56637061
Add together for total area
divide 187.50 by 12.5 to find hourly rate
187.50/12.50 = 15 dollars per hour
now divide 465 by 15 for number of hours
465/15 = 31 hours
double check by multiplying 31 by 15 ( 31 x 15 = 465)
