Answer:

Step-by-step explanation:

$slope=\frac{y_2-y_1}{x_2-x_1} \\\frac{8-4}{5-3} =\frac{4}{2} =2\\slope=2$

Solve the equation -4(3x+2)=88

Goshia [24]

Answer:

x=-8

Step-by-step explanation:

first do whats in the parenthess and it will look like this

-12x-8=88 now add 8 to 88 and you get 96

-12x=96 now you want x by itself so divide -12 into 96 and you get -8

x=-8

Find coordinates of the image of the point A(3,9) for a dilation with the scale factor of 2/3

tiny-mole [99]

Answer:

The coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)

Step-by-step explanation:

Given the point A with the vertices (3, 9) i.e. A(3,9)

As we know that If the scale factor is between 0 and 1, the image gets shrunk.

In order to dilation with a scale factor of 2/3, just multiply the x and y coordinates of the original point (3, 9) by 2/3.

i.e.

(x, y) → (2/3 x, 2/3 y)

so, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be:

A (x, y) → (2/3 x, 2/3 y) = A (2/3 (3), 2/3 (9)) = A'(2, 6)

Therefore, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)

A - g(x) = |x-5|+5 <br> B - g(x) = |x-5| <br> C - g(x) = |x|+5 <br> D - g(x) = |x+5|+5

n200080 [17]

Answer:

$g(x) = |x| + 5$

Step-by-step explanation:

Since both the original and transformed graph have the same x value for their vertex, there was no horizontal shift. However the vertex shifted up. Specifically it shifted up 5 units. Therefore:

$g(x) = f(x) + 5$

The plus 5 performs a translation up 5 units. Plugging in for f(x) it can be seen that:

$g(x) = |x| + 5$

If a 32 ft rope is cut into two sections with one section 7 times as log as the other section, how long is teh shorter piece?

steposvetlana [31]

The total length of the rope = 32 ft
It is cut into two sections, say x and y
But one section is seven times the other, say y=7x (shorter section being x)
Solving for x

x+y =32
x+7x = 32
8x=32
x=32/8 = 4 ft.
Therefore, the shorter piece is 4 ft long.
