3. solve each inequality and graph the solution on a number line.
a. 7 sx-4 s 10
b. 15 sr-352
c. 3x > -9 and 8 s 2x
d. x + 3 > 5 and - 4x 2-8
e. sx + 7 < 12 or -7x 2 -21
f. 4x s 20 or 3x + 1 -5

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

can you post the graph?

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
