Answer:

B

Step-by-step explanation:

B

x - 4 squared provides 2 real zeros that are the same. These two are not distinct.

The other two come from x^2 - 7x + 10 which has a discriminate of

sqrt(7^2 - 4*1*10) = sqrt(9) = +/- 3 leading to something real and different.

Carrie started with 12 ounces of water when she began her walk. When she was finished walking she had 2 1/4 ounces of water left

Elodia [21]

We are given with an initial value of water equal to 12 ounces of water and the final value of water is 2 1/4 or 2.25 ounces. Since the two substances are the same, we can use direct subtraction to determine what was consumed after walking. The answer is 12-2.25 equal to 9.75 ounces

Passing through (-2, 8) and PERPENDICULAR to y = 2x + 5

tangare [24]

Answer:

$y=\frac{-1}{2} x+7$

Step-by-step explanation:

The slope of a perpendicular line will always be the NEGATIVE RECIPROCAL of the slope of the original line.

y=2x+5

Because this equation is organized in slope-intercept form, y=mx+b, we can identify the slope of the original line is 2. The negative reciprocal of 2 is $\frac{-1}{2}$ . Therefore, the slope of the perpendicular line is $\frac{-1}{2}$ . So far, our equation looks like this:
