Answer:
x=4,y=9
Step-by-step explanation:
We want to solve the equation:
simultaneously.
Multiply the top equation by 3 and the bottom equation by 2 to get:
6y-15x=-6
6y+4x=70
Subtract the top equation from the bottom equation.
We substitute x=4 into 2y-5x=-2 to get:
Therefore the solution to the system is
(4,9)
Answer:
D
Step-by-step explanation:
On the way that this question is worded you would choose anything that would go up to 35 and anything below 35. Hope this helps you :)
X is 45
X-15=30
X=30+15
X=45
8x³-64x²+x-8 is factored by grouping
8x²(x-8)+1(x-8)
(8x²+1)(x-8) is your answer
