-8x – 14 = 7(-2 - 4x) + 4x<br> what is

Andru [333]

Answer:

<h2>x = 0</h2>

Step-by-step explanation:

$-8x-14=7(-2-4x)+4x\qquad\text{use the diastributive property}:\ a(b+c)=ab+ac\\\\-8x-14=(7)(-2)+(7)(-4x)+4x\\\\-8x-14=-14-28x+4x\qquad\text{add 14 to both sides}\\\\-8x-14+14=-14+14-24x\\\\-8x=-24x\qquad\text{add}\ 24x\ \text{to both sides}\\\\-8x+24x=-24x+24x\\\\16x=0\qquad\text{divdie btoh sides by 16}\\\\\dfrac{16x}{16}=\dfrac{0}{16}\\\\x=0$

Can somebody please help me ? I gotta turned this in 10 minutes .

Arturiano [62]

Answer:

y = $-\frac{1}{3}x-\frac{2}{3}$

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

m = Slope of the line

b = y-intercept

Since, slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

m = $\frac{y_2-y_1}{x_2-x_1}$

Since, the given line passes through two points (-5, 1) and (4, -2)

Slope of the line 'm' = $\frac{1+2}{-5-4}$ = $-\frac{1}{3}$

Equation of the line will be,

y = $-\frac{1}{3}x+b$

Since, this line passes through (4, -2),

-2 = $-\frac{4}{3}+b$

b = $\frac{4}{3}-2$

b = $-\frac{2}{3}$

Therefore, equation of the line will be,

y = $-\frac{1}{3}x-\frac{2}{3}$

Which expression is equivalent to (2x + 4)2 – (2x2 + 6)?

Anettt [7]

Answer:

The correct option is B). $2x^{2}+16x+10$

Step-by-step explanation:

Given function is $(2x+4)^{2}-(2x^{2} +6)$

On simplifying,

= $(2x+4)^{2}-(2x^{2} +6)$

= $[4x^{2}+16x+16]-(2x^{2} +6)$

= $4x^{2}+16x+16-2x^{2}-6$

= $2x^{2}+16x+10$

Thus, The correct option is B). $2x^{2}+16x+10$
