For this case we must solve the following questions:

Question 1:

We must solve the following quadratic equation:

We subtract 1 from both sides of the equation:

We apply square root to eliminate the exponent:

The solution is not real.

Option D

Question 2:

We must solve the following quadratic equation:

We factor the equation, that is, we must look for two numbers that when multiplied give as result 24 and when summed with -10. These numbers are -6 and -4:

The roots are:

Option D

Question 3:

We must complete squares of the following expression:

We add

Then:

Then, to complete the square, add it to both sides

Option C

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
