Answer:
11 miles
Step-by-step explanation:
Do 8+3 or just count the number of spaces on the number line
For #3.
Zeros are 3 and -1 (plot them on the x-axis as a point)
Axis of symmetry is halfway between those so it’s: x=1
Vertex is (1, -4)
Y-intercept is (0,-3)
Domain is always all real numbers
Range is y is greater than or equal to -3
To find the x coordinate of the midpoint, add the x coordinates and divide by 2
(-5+3)/2 = -2/2 = -1
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
(3+-1)/2 = 2/2 = 1
(-1,1)
