Step-by-step explanation:
thats what i worked out and got
We are given that a car starts a journey with a full tank of gas. The equation relates the number of gallons of gas (y) left in the tank to the number of miles the car has traveled(x).
A. We will find y intercept by substituting x=0 in our equation,
Now let us find our x-intercept by substituting y=0 in our equation,
Therefore, x-intercept is 320 and y-intercept is 16.
B. Our x-intercept represents that after travelling 320 miles there were 0 or none gallons of gas left in tank.
C. Our y-intercept represents that there were 16 gallons of gas in car tank when car started the journey.
Hello : here is a solution :
The midpoint is (-2, -9).
Using the midpoint formula:
(x1+x2/2, y1+y2/2)
(-12+8/2, -7+(-11)/2)
(-4/2, -18/2)
(-2, -9)
Use the Pythagorean theorem A^2 + B^2 = C^2. C is the slant length. Hope this helps.
