<span>-x + 5y= -18 so x = 5y + 18
5x-9y=10
substitute </span>x = 5y + 18 into 5x - 9y = 10
5x - 9y = 10
5(5y + 18) - 9y = 10
25y + 90 - 9y = 10
16y = - 80
y = -5
x = 5y + 18
x = 5(-5) + 18
x = -25 + 18
x = -7
answer
(-7, -5)
$.60 a lb.
Just divide $1.50 by 2.5lbs.
Hi!
30 = x
f(x) = -1/5x - 14 find x when f (x) = -8
Set the equation equal to -8
-8 = -1/5x - 14
Add 14 to both sides.
6 = -1/5x
Multiply both sides by -5.
30 = x
Hope this helps! :D
<span>{x | x ≤ -8} hope this helps</span>
What? This isn’t a question
