Two lines, C and D, are represented by the equations given below: Line C: y = X + 10
Line D. Y = 3X + 2
Which of the following shows the solution to the system of equations and explains why?
© (5, 17), because one of the lines passes through this point
(5, 17), because the point lies between the two axes
© (4, 14), because the point does not lie on any axis
© (4, 14), because both lines pass through this point

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

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

ask the math teacher she or he would know lol.
