-y=2x +1
y= -2x -1
slope = -2/-1
slope= 2
If you're graphing this, you would go up two and right 1

Higher Order Thinking a carpenter plans to extend the length of rectangular desk by 7 feet. Let x represent the desk's original

abruzzese [7]

Answer:

d. 9x + 63 and 63 square feet

Step-by-step explanation:

Given

Original

$Length = x$

$Width = 9$

Extended

$Length = x + 7$

$Width = 9$

$Area = 9(x + 7)$

Required

Determine an expression and the value of the extended area

First, we calculate the area of the original desk

$A_1 = x * 9$

$A_1 = 9x$

From the given parameters, we have:

$Area = 9(x + 7)$ --- area of the new surface

Open bracket

$Area = 9x + 63$

The area of the new surface is the summation of the area of the original desk and the area of the extended portion (E)

So:

$Area = A_1 + E$

Make E the subject

$E= Area - A_1$

$E= 9x + 63 - 9x$

$E= 63$

Hence, the area of the extended portion is 63

HELP 10PTS AND BRAINLIESTThe image of a triangle after it has been dilated with a center of dilation at the origin has vertices

Gala2k [10]

Answer:

C is (-18, 24)

Scale factor 1 1/3

A is (9, - 4 1/2) *4 1/2 is also 4.5

Step-by-step explanation:

When we take a look at image B (-24, -12) and pre image B (-18, -9),

we can work out the scale factor by

(-24/-18) and (-12/-9) both equal 4/3

So using the scale factor to go from the pre image to the image,

We can find C coordinate by multiplying pre image C by the scale factor.

C is (-13.5 x 4/3) and (18 x 4/3)

C is (-18, 24)

The scale factor is 4/3, which is the mixed numeral of 1 1/3.

To find the pre image of point A we divide the image by the scale factor

A is (12/(4/3)) and (-6/(4/3))

A is (9, - 4 1/2)

Hope this helps,
