Answer:

Answer is option B.

B. (3,-6) and (7,-6)

Step-by-step explanation:

Slope = change in y / change in x

Slope = (y2-y1)/(x2-x1)

For slope to be zero. i.e

0 = (y2-y1)/(x2-x1)

Cross multiple

0*(x2-x1) = (y2-y1)

(y2-y1) = 0.

Implies that slope of a line will be zero when change is y is zero.

So let examine all the line points in our options to determine our answer.

A. (12, 9) and (12,6)

(y2-y1) = 6 - 9 = -3

B. (3,-6) and (7,-6)

(y2-y1) = -6 - (-6) = -6+6 = 0

C. (1,4) and (2,5)

(y2-y1) = 5 - 4 = 1

D. (-9,7) and (9,-7)

(y2-y1) = -7 - 7 = -14

Haven examine our option, we see that our change in y is zero for option B, therefore at point (3,-6) and (7,-6) the slope is zero

Answer:

The equation of this line would be y = -8

Step-by-step explanation:

Since y = 9 is a horizontal line, the parallel line must also be horizontal. All horizontal lines can be written as y = (a number). That number can be found as the y-coordinate in the ordered pair, which is -8.

y = -8

A yoga studio sells monthly memberships. The function f(x) = −x2 + 50x − 264 models the profit in dollars, where x is the number

Keith_Richards [23]

Answer:

x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made.

Step-by-step explanation:

f(x) = −x² + 50x − 264

−x² + 50x − 264 = 0

-x² + 44x + 6x - 264 = 0

-x(x - 44) + 6(x - 44) = 0

(x - 44)(-x + 6) = 0

x = 6, 44

Can someone explain and answer please??

Nat2105 [25]

Simplify the ration expression
$\frac{3x-6}{x-2}$

start by seeing if anything in the numerator or denominator can be factored,
you should notice that you can factor out a 3 from 3x-6 in the numerator

when you do so, the result is
$\frac{3 *(x-2)}{x-2}$

now, since there is an x-2 in the numerator and denominator, they "cancel" out since

$\frac{x-2}{x-2} =1$
however, only when $x \neq 2$
since $\frac{0}{0} \neq 1$

when you cancel out the x-2, you're left with 3

hence, your answer is C
