Answer:
12x + 27
Step-by-step explanation:
3(4x+9) = 12x + 27
Because it's decreasing, you use the formula (1-x/100)y with x the percentage decreased which is here 40, and y the number decreased which is here 90
So we get
(1-40/100) * 90
(100/100 - 40/100) * 90
60/100 * 90
5400/100
54
So 90 decreased by 40% is 54
Hope this Helps :)
I believe it’s the last option sorry if I’m incorrect
X+Y=6. Y=6-X 2X-(6-X)=-12 2X-6+X=-12. 3X=-6. X=-2. Y=6-(-2). Y=8
SOLUTION: { (x,y) | (-2,8) }
That’s for #1.I can’t read the points for #2
