X = - 4
2(-4-8) = -4 + 5(-4)
5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2
First Collect like terms:
5x x 2y, +3x x 2,and +8xy x 2
16x x 2y -4x x 2 - 4y x 2—> Multiply the numbers:
Multiply the numbers 16 x 2
16 x 2 = 32
Now multiply the numbers 4 x 2
4 x 2 = 8
Now Multiply the numbers 4 x 2 again
4 x 2 = 8
= 32xy - 8x- 8y
Factor 8 from the expression
Final Answer:
8(4xy-x-y)
I’m not really sure about my answer but i hope it helps!
Sorry if its wrong..
Stay Safe guys!
Difference in doughnuts = 50 - 40 = 10
Difference in money = 15 + 5 = 20
20 ÷ 10 = $2
Each doughnut costs $2
<em>Check:</em>
40 x 2 + 5 = $85
50 x 2 -15 = $85
Ravi has $85 at first.
Each doughnut costs $2
Answer:
f(x)=-3x+4
(can't see some of your choices)
Step-by-step explanation:
We want x to be independent means we want to write it so when we plug in numbers we can just choose what we want to plug in for x but y's value will depend on our choosing of x.
So we need to solve for y.
9x+3y=12
Subtract 9x on both sides
3y=-9x+12
Divide both sides by 3:
y=-3x+4
Replace y with f(x).
f(x)=-3x+4
