The distance (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equation below: car a: y = 45x + 20 car b: y = 35x + 60 after how many hours will the two cars be at the same distance from their starting point and what will the distance be? 3 hours, 200 miles 3 hours, 180 miles 4 hours, 200 miles 4 hours, 180 miles

45x+20 = 35x+60

45x = 35x+40

10x = 40

x = 4 hours

45(4)+20 = 200

4 hours, 200 miles

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
