Consider the following equations: y = 2x-3

y = 2x

y = 2x + 2

y= 2x + 5

a. Discuss the similarities and differences of the graphs of these equations. (Use
a graphing calculator if you have one.)

a. Same slopes; same y-intercepts

b. Same slopes; different y-intercepts

c. Different slopes; different y-intercepts

d. Different slopes; same y-intercepts

Please select the best answer from the choices provided

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
