Answer:

Step-by-step explanation:

What is the question? If you want to know how to graph this equation, it's usually easiest to start with the intercepts, i.e., the points where the line crosses the axes.

y = ½x + 3 tells you that the line crosses the y-axis at (0,3), so plot that point.

Then let y = 0 and solve for x.

0 = ½x + 3

x = 6

The line crosses the x-axis at (6,0), so plot that point as well.

Then draw the line passing through those two points.

Pira drives 825 miles to California. The trip takes him 17 hours. He uses 38 gallons of gas on the trip, which costs him $125. F

Speed = Distance / time:

Speed = 825 miles / 17 hours

Speed = 48.529 miles per hour. (Round the answer as needed).

Gas mileage = miles traveled / gallons used

Gas mileage = 825 miles / 38 gallons = 21.71 miles per gallon (Round answer as needed).

Unit rate of gas = Total money spend / gallons bought:

Unit rate of gas = $125 / 38 gallons = $3.289 per gallon.

So since its a right triangle, we can use the pythagorean theorem, which is $leg^2+leg^2=hypotenuse^2$ . Since we know that 2 and 3 are our legs and x is our hypotenuse, we can solve the equation as such:
