Answer:
y=3x+4
Step-by-step explanation:
since the line is parallel it has the same slope so we have y = 3x + b. plug in the point (2,10) to get 10 = 3*2 + b, so b=4. so the equation is y = 3x +4
Answer:
x = -4
Step-by-step explanation:
8x = 8 + 2(x-10) + 3x
simplify
8x = 8 + 2x - 20 + 3x
simplify again
8x = 5x - 12
subtract 5x from both sides
3x = -12
divide both sides by 4
x = -4
Answer:
Factoring by grouping effectively breaks down the polynomial into easy-to-solve smaller polynomials. The goal is to isolate each term in a separate group and then add them together to finally get the original polynomial.
Step-by-step explanation:
The first thing we'll do is look for two numbers that multiply together to give -9. These will be our "groupings". Once we find these, we'll start grouping other terms in an alternating fashion until we can't break any more of the terms apart.
We find 2 and 3 which when multiplied give -6, so these are our groupings for this problem:
2x3(-9)=-18 + 5x(-9)=-45 + 4
