PLEASE HELP ME

Multiply each equation by a constant that would help to eliminate the y terms.

2 x - 5 y = -21. 3 x - 3 y = -18.

What are the resulting equations?

A) 6 x - 15 y = -63. -15 x + 15 y = 90.

B) 6 x -15 y = 63. -15 x + 15 y = 90.

C) 6 x - 15 y = -63. -15 x + 15 y = -90.

D) 6 x - 15 y = -63. -15 x + 15 y = 90.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

597

step-by-step explanation:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
