Please help, see attachment for equation!
Alekssandra [29.7K]

Answer:

The answer to your question is the last option

Step-by-step explanation:

Quadratic equation

                                2 = - x + x² - 4

Order the equation from the highest power to the lowest power. Do not consider 2 because it is not consider in the options given.

                               x² - x - 4  = 0

Identify a, b and c

                              (1) x² -(1) x - 4 = 0

    a = 1    b = -1    c = - 6      

Substitution              

                              \frac{-(-1) +- \sqrt{(-1)^{2} - 4(1)((-4)}}{2(1)}

Find an equation of the line perpendicular to the graph of 14x-7y=8 that passing through the point at (-2,5).
MAXImum [283]

Answer:

2x + 4y = 16.

Step-by-step explanation:

14x - 7y = 8

Convert to slope-intercept form:

-7y = -14x + 8

y = 2x - 8/7

The slope is 2 so the line perpendicular to it has a slope of -1/2, so we have:

y = 1/2x + c

This line passes through the point (-2, 5) so:

5 = -1/2* (-2) + c

5 = 1 + c

c = 5 - 1 = 4

So our equation is y = -1/2x + 4.

Convert to standard from

4y = -2x + 16

2x + 4y = 16.
