Sub a =3 and b = 5 into the expression above you get:

8*3+6(2*5-7)

then use bedmas accordingly (this is the order of arithmetic operations)

8*3+6(2*5-7)
=24+6(10-7)
=24+6(3)
=24+18
=42

Denise buys flour in bulk for her bakery. The cost per pound of flour is graphed below. Which BEST describes the function of the
bonufazy [111]
Based from the graph, I think the answer is D. a piece-wise function with separate pieces of linear and step-functions. This is because as you can see from the graph, for intervals [0,1], [5,6], and [10,11] the function is linear. On the other hand, for the remaining intervals, it has a constant value which can be described as a step function.

What is the equation of the directrix of the parabola given by the equation y2 = -24x?
erma4kov [3.2K]

The equation of the directrix of the parabola given is x = 6, Option D is the correct answer.

<h3>What is Directrix of a Parabola ?</h3>

A parabola is a U shaped curve whose all point are at same distnace from a  point called as focus and a line called as Directrix .

The equation of the parabola given is

y² = -24x

When the standard equation of parabola is

 (y - k)² = 4p (x - h),

where the focus is (h + p, k) and the directrix is x = h - p.

here h = 0

p = -24/4 = -6

x =  0 - (-6)

x = 6

Therefore Option D is the correct answer.
