Write an equation in slope -intercept form for a line that passes through (-2,7) and (14,21)
Georgia [21]
(-2,7) and (14,21)

Find the slope by using the formula m =  \frac{y2 - y1}{x2 - x1}

Plug in the numbers. m = \frac{21 - 7}{14 - - 2} 
 \\  m= \frac{14}{16}  =  \frac{7}{8} 


Write it in point slope form first

y - y1 = m(x - x1)
y - 7 = 7/8(x - -2)
y - 7 = 7/8x + 1.75
   + 7            +7

y = 7/8x + 8.75

Our final equation would be: <span>y = 7/8x + 8.75</span>

One of the two supplementary angles is 1/3 the measure of the other. Find the angles.
Furkat [3]

Answer:

45 and 135

Step-by-step explanation:

If angles, with measurements a and b, are supplementary, then a and b have sum 180 degrees.

So we have the following equation so far:

a+b=180

Now we also have that one angle has a measurement that is 1/3 the value of the one.

So we also have 3a=b which means we are letting the angle whose measurement be a have 1/3 the value of b.

So lets plug the second equation into first giving us:

a+3a=180

Add like terms:

4a=180

Divide both sides by 4:

a=180/4

a=45

So b=3a=3(45)=135.

So the angles in question have measurement s 45 and 135.

The lengrh of a rectangle is represented by the function L(x) = 5x. The width of that same rectangle is represented by the funct
MrRissso [65]

Step-by-step explanation:

just multiply the 2 together to get the area

it would just be

(5x) \times (2{x}^{2} - 4x + 13)

use the distributive property

10 {x}^{3}  - 20 {x}^{2}  + 65

unless you want to simplify the answer, this would be the answer

simplified, it would be

5(2{x}^{3}  - 4 {x}^{2}  + 13)
