Answer:
a straight vertical line on x 4
Step-by-step explanation:
Answer: The polynomial
= y² - 5y - 4.
Step-by-step explanation:
Let the polynomial = f(y)
Therefore
y² -5y + 1 - f(y) = 5
f(y) = y² - 5y + 1 - 5
f(y) = y² - 5y - 4
The polynomial = y² - 5y - 4.
Check:
y² - 5y + 1 - ( y² - 5y - 4)
Open the bracket with the minus
y² - 5y + 1 - y² + 5y + 4
y² - y² - 5y + 5y + 1 + 4
= 0 - 0 + 5
= 5.

Answer:
a) His average speed is $48.53 miles/hour
b) His gas mileage is 21.71 miles per hour.
c) 1 gallon of gas is 1 gallon of gas = $3.29.
Step-by-step explanation:
A) Pira drives to California in 17 hours = 825 miles
Pira drives to California in 1 hours = (825/17) miles
= 48.53 miles/hour.
Therefore, his average speed is $48.53 miles.
B) Pira uses 38 gallons to drive 825 miles
Pira uses 1 gallon to drive 825/38 miles-per-hour
= 21.71 miles-per-hour
Therefore, his gas mileage is 21.71 miles per hour.
C) 38 gallons of gas cost = $125
1 gallon of gas = $125/38
1 gallon of gas = $3.29.
