The answer would be y=-x-4

3-(-2)/-1-4 is the slope
Simplified, the slope is -1
So far, we have y=-1x+b.
We know that 4,-2 is a point on this line, so we plug it in.
-2=-1(-2)+b which is the same as -2=2+b
Therefore b=-4
Then plug b back in. We get
y=-x-4 which is the answer

Answer:

<h3>The slope is -1.</h3>

Step-by-step explanation:

To find an equation of the line that passes through the points, you have to use the slope formula.

Slope:

\Rightarrow \sf{\dfrac{y_2-y_1}{x_2-x_1} }

y2=3

y1=(-2)

x2=(-1)

x1=4

Solve.

3--2/-1-4=5/-5=-1

The slope is -1.

Does -2(11-12x)=-4(1-6x) does it have one solution or no solution or many solutions
VARVARA [1.3K]

Answer:

no solutions

Step-by-step explanation:

-2(11-12x)=-4(1-6x)

Distribute

-22 +24x = -4 +24x

Subtract 24x from each side

-22 +24x-24x = -4 +24x-24x

-22 = -4

This is never true, so there are no solutions

Can someone explain the process of getting to Angle A? I know the answer is 44.1 but I need to show my work so can someone show
dsp73

Answer:

Step-by-step explanation:

First you have to calculate CB in order to use sin law to calculate ∠A

CB=\sqrt{18.4^{2} -13.2^{2} }

CB=12.8(correct to nearest tenth)

After that, use sin law to calculate ∠A,

\frac{18.4}{sin90} =\frac{12.8}{sinA}       or    \frac{sin90}{18.4} =\frac{sinA}{12.8}

sinA=0.695...

A=44.079...

  =44.1(corrext to the nearest tenth)

Is that clear enough for you?

Miguel wants to wallpaper the back wall of his bedroom. the wall is in the shape of a rectangle. its length is 13 feet and its w
Bingel [31]
First of all lets find the area of the rectangle.
13 ft × 12 ft = 156 square feet.
Now lets find the price which is $8 / square foot. Using proportions we get:
$8/sq ft × 156 sq ft. Simplifying we get
$8 × 156 = $1248.
The wallpaper will cost $1248
