forsale [732]

Answer:

2g2 - 9g - 1

Step-by-step explanation:

(2g2 - 9g) - 1

2.1 Factoring 2g2-9g-1

The first term is, 2g2 its coefficient is 2 .

The middle term is, -9g its coefficient is -9 .

The last term, "the constant", is -1

Step-1 : Multiply the coefficient of the first term by the constant 2 • -1 = -2

Step-2 : Find two factors of -2 whose sum equals the coefficient of the middle term, which is -9 .

2 + 1 = -1

-1 + 2 = 1

Find the equation (in terms of x ) of the line through the points (-4,-4) and (2,4)

Greeley [361]

Answer:

$y=\frac{4}{3}x+\frac{4}{3}$

Step-by-step explanation:

Let $(x_1,y_1)\rightarrow(-4,-4)$ and $(x_2,y_2)\rightarow(2,4)$ :

Determine slope

$m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{4-(-4)}{2-(-4)}\\ \\m=\frac{4+4}{2+4}\\ \\m=\frac{8}{6}\\ \\m=\frac{4}{3}$

Use either coordinate point to find "b", the y-intercept

$y=mx+b\\\\4=\frac{4}{3}(2)+b\\ \\4=\frac{8}{3}+b\\ \\\frac{4}{3}=b$

Final Equation

$y=\frac{4}{3}x+\frac{4}{3}$
