Answer:
- 90
Step-by-step explanation:
In y = mx + b form, the slope will be in the m position and the y int will be in the b position
y = 6x - 5.....the slope is 6. A parallel line will have the same slope
with a y int of 7....
y = 6x + 7 <===
The expression represents the number of gallons used is m/22.
Given
Nikki can drive her car 22 miles on each gallon of gasoline.
<h3>What is the unit rate?</h3>
A rate is a ratio that is used for comparing two different kinds of quantities which have different units.
To find the number of gallons used we will divide the total distance traveled by distance traveled in one gallon.
Therefore,
If Nikki drives m miles, the expression represents the number of gallons used is;


Hence, the expression represents the number of gallons used is m/22.

The answer is 7.
f(a) = 2a-1, 3f(a) = 3(2a-1) = 15 -> a=2 so f(2a)=f(4)=7
Domain: The set of possible values of x
Range: The set of possible values of y
Zeros: The x-intercepts (what value of x is on the x-axis)
Discontinuities: Where the graph stops (and restarts somewhere else)
Asymptotes: The graph cannot cross this line (vertical, horizontal, oblique)
