Answer:
Option D is correct.
$408.04 the gas would cost for this car to travel 2,727 typical miles
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity 1 such as 3 miles per second or 4 kilometer per hour
As per the statement:
A car averages 27 miles per gallon.
⇒
Total distance of car travel typical miles = 2727 miles.
Substitute the given values we have;
It is also given that if gas costs $4.04 per gallon.
then;
In 1 gallon of gas = $4.04
then;
in 101 gallons of gas =
Therefore, $408.04 the gas would cost for this car to travel 2,727 typical miles
Answer:
y = - 2x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 8, 22) and (x₂, y₂ ) = (3, 0)
m = =
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 0), then
0 = - 6 + c ⇒ c = 0 + 6 = 6
y = - 2x + 6 ← equation of line
