What is 10+10 (2a-4)+(8a-6) using distributive property

1 answer:

3 0

The solution is solved as the following:
10 + 10(2a - 4) + (8a - 6)
10 + (10 * 2)a + (10 * -4) + 8a - 6
10 + 20a -40 + 8a -6
28a - 36

If you vertically stretch the absolute value parent function, f(x) = |x|, by a factor of 5, which is the equation of the new fun

I believe it is f(x)=5|x|
I suggest you get a second opinion, though

Find the slope of the line graphed in the diagram and choose the correct answer from the choices below. The two intercepts are (

kolezko [41]

1.2 is the slope of the line graphed in the given diagram

<u>Step-by-step explanation:</u>

We can use the given points (0, 3) and (-2.5, 0) to solve.

Slope formula is given by

$\text { slope, } m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Given two intercepts:

$\left(x_{1}, y_{1}\right)=(0,3) \text { and }\left(x_{2}, y_{2}\right)=(-2.5,0)$

By substituting these in the slope equation, we get

$\text { slope, } m=\frac{0-3}{-2.5-0}=\frac{-3}{-2.5}=\frac{3}{2.5}=1.2$

Write an equation in slope-intercept form from the points (0, 3) and (-4,-1)

Bezzdna [24]

Answer:

y = x + 3

Step-by-step explanation:

Slope-intercept form is represented by the formula $y = mx + b$ . We can write an equation in point-slope form first, then convert it to that form.

1) First, find the slope of the line. Use the slope formula $m = \frac{y_2-y_1}{x_2-x_1}$ and substitute the x and y values of the given points into it. Then, simplify to find the slope, or $m$ :

$m = \frac{(-1)-(3)}{(-4)-(0)} \\m = \frac{-1-3}{-4-0} \\m = \frac{-4}{-4} \\m = 1$

Thus, the slope of the line must be 1.

2) Now, since we know a point the line intersects and its slope, use the point-slope formula $y-y_1=m(x-x_1)$ and substitute values for $m$ , $x_1$ , and $y_1$ . From there, we can convert the equation into slope-intercept form.

Since $m$ represents the slope, substitute 1 in its place. Since $x_1$ and $y_1$ represent the x and y values of a point the line intersects, choose any one of the given points (either one is fine) and substitute its x and y values into the equation, too. (I chose (0,3).) Finally, isolate y to find the answer:

$y-3=1(x-0)\\y-3 = x\\y = x + 3$
