19) The graph of the line y=2x-3 is shown below. If the slope of the line is doubled, the new equation
is y= 4x - 3. Which is a correct comparison of the two lines?
a) The x-intercept and y-intercept change
b) The x-intercept and y-intercept stay the
same
c) The x-intercept stays the same and the y-
intercept changes
d) The x-intercept changes and the y-intercept
stays the same

4x and 6y

im not sure though

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

the answer is -1 1/5, also a
