Answer: -9
18/x = -2
⇔ x = 18/(-2)
⇔ x = -9
Step-by-step explanation:
Answer:
When a dilation in the coordinate plane has the origin as the center of dilation, you can find points on the dilated image by multiplying the x- and y-coordinates of the original figure by the scale factor. For scale factor k, the algebraic representation of the dilation is (x, y) → (kx, ky). For enlargements, k > 1.
Answer: 3x > -28
Step-by-step explanation: We wrote an inequality to represent this situation.
Additionally, to solve this inequality divide both sides of the inequality by 3.
3x/3 > -28/3
x > -9 1/3
The answer is 840 because 300+240+180+120= 840!
