Answer:

Equation: 139 + 3x + (5x - 10) + (10x - 9) + 3x = 540 (not simplified, see below for simplified)

x = 20

Step-by-step explanation:

If the sum of the angles is 540°, then that means you add them up to get 540°.

139 + 3x + (5x - 10) + (10x - 9) + 3x = 540

129 + 8x + (10x - 9) + 3x = 540

120 + 18x + 3x = 540

120 + 21x = 540

21x = 420

x = 20

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} &#10; \\  m= \frac{14}{16}  =  \frac{7}{8} &#10;

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>

What is x^2+x-20=0. <br> please help
zepelin [54]
X² + x - 20 = 0

x² = x * x
x = the sum of the factors of -20
-20 ⇒  1 x 20
            2 x 10
          - 4 x 5 ⇒ only these factors can arrive to a sum of 1

(x - 4)(x + 5) = x(x+5) - 4(x+5) = x² + 5x - 4x - 20 = x² + x - 20

x - 4 = 0
x = 4

x + 5 = 0
x = -5
