Answer:

y = 3x-2

Step-by-step explanation:

We have the y intercept  (where it crosses the y axis)

It crosses at y=-2

(0,-2)  We need another point to find the slope.

Another point is (1,1)

The formula for slope is

m=(y2-y1)/ (x2-x1)

We have 2 points (0,-2) and (1,1)

   = (1--2)/(1-0)

   = (1+2)/(1-0)

    3/1

m=3

The slope is 3 and the y intercept is -2

We can use the slope intercept form of the equation

y= mx+b where m is the slope and b is the y intercept

y = 3x-2

Answer:

y = 3x - 2

Step-by-step explanation:

Two of the coordinates are (2, 4) and (1, 1). The slope of these is 3/1, or 3. Plug this back in to get that the slope-intercept form is y = 3x - 2.

Okay here we go!

The answer is D. 

Because when you solve the equation you get 2 and that means the arrow has to be or end at 2.

PLEASE HELP!! find the value of x. attached image.
slamgirl [31]

Answer:

x     =   4.712145

Step-by-step explanation:

Given a=20 and b=28,

c = 4√74 = 34.409301068171

∠α = 35.538° = 35°32'16" = 0.62025 rad

∠β = 54.462° = 54°27'44" = 0.95055 rad

Area = 280

Perimeter = 82.409301068171

<h2><u>_____________________________________</u></h2>

Let's solve your equation step-by-step.

9x−8=34.409301

Step 1: Add 8 to both sides.

9x−8+8=34.409301+8

9x=42.409301

Step 2: Divide both sides by 9.

\frac{9x}{9} =\frac{42.409301}{9}

x=4.712145

<h2>Answer:</h2><h2>x=4.712145</h2>
