2x+5y=10 x-3y=-6 how do i get the point of intersection

1 answer:

8 0

Multiple the second equation by 2 and subtract it from the first

2x + 5y = 10
2x - 6y = -12

now subtract

11y = 22
y = 2

Plug y = 2 in to either equation
x - 3(2) = -6
x - 6 = -6
x = 0

The point at where they intersect is (0, 2)

Factor the following using the GCF (Greatest Common Factor):

wariber [46]

Answer:

Part (A) Factored using GCF is: 2(x² + 2) → (GCF is 2)

Part (B) Factored using GCF is: 2x³(3x-1) → (GCF is 2x³)

Step-by-step explanation:

Greatest Common Factor or GCF, is whichever value that fits into both terms. For example if you have 2, 4, and 6, 2 is the biggest value that fits into all 4 terms.

To factor using GCF, simply find the GCF of both terms, and take it out, then multiply what you have remaining by whatever the GCF is.
