PLEASE HELP

Masja [62]

Answer:

y = 50x + 20

Step-by-step explanation:

$m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

Use the slope-intercept formula to find the slope.

$m = \frac{120 - 20}{2 - 0}$

$m = \frac{100}{2} = 50$

The y-intercept is where the line crosses the y-axis.

Factor the polynomials comletely, then solve 9x^2 +66x+21 = 0

son4ous [18]

Answer:

x= -1/3

x = -7

Step-by-step explanation:

9x^2 +66x+21 = 0

a=9 b=66 c=21

quadratic formula

x=(-b +/- square root of (b^2 – 4ac))/(2a)

x = (-66 +/- square root of (66^2 -4*9*21))/(2*9)

x = (-66 +/- square root of (4356 -756))/(18)

x = (-66 +/- square root of (3600))/(18)

x = (-66 +/- 60)/18

split the fraction

(-66 +/- 60)/18 = -6/18 and -126/18 because of the +/-

x = -6/18 x = -126/18

x = -1/3 x = -7
