Answer:
23
Step-by-step explanation:
3(-2)2-2(-2)+7
3(4)-(-4)+7
12+4+7
The constant of proportionality is k = y/x.....k = 40/200 = 1/5
y = mx + b
slope(m) = 1/5
(200,40)...x = 200 and y = 40
now we sub...we r looking for b, the y int
40 = 1/5(200) + b
40 = 40 + b
40 - 40 = b
0 = b
so ur equation is : y = 1/5x
if pop star earned 800
800 = 1/5x
800 * 5 = x
4000 = x
Hello there. I did one part of your question.
4x + 2y + z = 8

Answer:
x=-5
Step-by-step explanation:
7x+35=0
subtract 35 from both sides
7x=-35
divide both sides by 7
x=-5
