xz_007 [3.2K]2 years ago
7 0

Step-by-step explanation:

{x}^{2}  + 2x - 2 = 0

Now Adding three on both sides we get

{x}^{2}  + 2x - 2 + 3 = 0 + 3

{x}^{2}  + 2x + 1 = 3

{(x + 1)}^{2}   = 3

Write the equation of the line, in standard form, that has a y-intercept of 2 and is parallel to 2x + y = -5. Include your work
PtichkaEL [24]
We first convert the given equation of the line to slope-intercept form, giving us,
                                       y = -2x - 5
The slope is -2 and the y-intercept is -5. For the new line, the slope should also be equal to -2 and the y-intercept be equal to 2. The equation is then equal to,
                                      y = -2x + 2
