Answer:
Step-by-step explanation:
The given expression is
To factor this polynomial, we just need to extract the common factor. Or you can see as the greatest common factor.
What is the greatest common factor between 8 and 16?
16: 1, 2, 4, 8, 16.
8: 1, 2, 4, 8.
You can observe that the greatest common factor is 8, so we extract it from both numbers
Notice that we placed the GCM in the front as a product, if we don't do that, it would be completely wrong, because we can change the equivalence of the expression. Now, notice that each variable have different coefficients, that is because if you extract the GCM, you need to placed its quotients as coefficients.
Therefore, the factor of the polynomial is
9514 1404 393
Answer:
7x +9y = -1
Step-by-step explanation:
The standard form of the equation for a line is ...
ax +by = c
where a, b, c are mutually prime integers and a > 0.
We can get this form by multiplying the equation by 9, adding 7x+27.
y - 3 = -7/9(x +4)
9y -27 = -7x -28 . . . . . multiply by 9, eliminate parentheses
7x +9y = -1 . . . . . . . . . add 7x+27 to both sides
