mark brainliest if right :)
D!
One clue to this (if you don’t just multiply 0.22 by 2.95) Is that this is the only value above 1. since the ending equation has a number larger than the original, this is a give away! Hope this helps :)
Oh what you mean by this is all because this can mean like four different so explain more
Answer:
x >-11
Explanation:
2x+7>-15
Subtract 7 from both sides
2x >-15-7
Simplify-15-7 to -22
2x >-22
Divide both sides by 2
22
x > - ___
2
Simplify 22/2 to 11
x >-11
3y = -1/2x + 2 . . . . . . . . (1)
y = -x + 9 . . . . . . . . (2)
substituting (2) into (1), we have
3(-x + 9) = -1/2x + 2
-3x + 27 = -1/2x + 2
-1/2x + 3x = 27 - 2
5/2x = 25
x = (2 x 25)/5
x = 10
From (2)
y = -10 + 9
y = -1
solution (10, -1)
