How do you solve
7x=-35
-8x+9y=4

x=-5 and y=-4

Step-by-step explanation:

7x=-35

-8x+9y=4

To get x

Divide equation one by 7

7x/7=-35/7

x=-5

Substitute for x in equation ii

-8(-5)+9y=4

40+9y=4

9y=4-40

9y=-36

y=-4

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
