What is the equation of the line that passes through (20, 500) and (16, 300)

hi there! here's my answer for you...

y = 50x − 500

Explanation:

Use the slope formula and slope-intercept form y = mx + b to find the equation.

hope this helps. have a good one!

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
