Answer:

C. $f(x)=(x+1)^2-4$

Step-by-step explanation:

A. the graph is a straight line with slope 1. It goes up/down infinitely far so the range is all real numbers. Not A!

B. The graph is a straight line with slope -4, so, like the function in A, the range is all real numbers. Not B!

D. The graph is an absolute value function y = |x|, reflected over the x-axis, shifted right 3 units, then shifted down 4 units. So the graph starts witha "vee" shape opening up, becomes a vee opening <u>down</u>, then ultimately gets shifted down 4 units. The range is all real numbers less than or equal to -4.

See the attached graphs. image2 is the function in answer choice D.

Suppose a right cylinder was bent into a U-shape and was compared to another right cylinder. What can be said about their volume

xenn [34]

Answer:

The volume of the U-shape will be<u> half </u>the volume of the original right cylinder.

Step-by-step explanation:

If we are given a right cylinder and it was bent into a U shaped then this U-shaped figure could also be considered as a half cylinder.

We could see from the figure attached how this shape looks like.

and now the volume of this half cylinder will be half the volume of the actual right cylinder.

Answer:

--------------------------------------------------

Step-by-step explanation:

60+x-45+x=180

60-45+2x=180

15+2x=180

2x=180-15

2x=165

x=165/2

x=82.5

y = x2 − 6x 8 2y x = 4 the pair of points representing the solution set of this system of equations is___ and ___?

mariarad [96]

Some operators are missing.
If the right equations are y = x^2 -6x +8 and 2y + x =4
This is the solution

2y + x = 4
2y = -x +4
y = -x/2 + 2

y = x^2 -6x + 8 = -x/2 + 2

2x^2 - 12x + 16 = -x + 4
2x^2 -11x +12 = 0

Factor

(x-4)(2x-3)=0

x= 4 and x =3/2

y = -x/2 +2

y = -4/2 + 2 = 0
y = - (3/2)/2 + 2 = -3/4 + 2 = 5/4

Answer (4,0) and (3/2, 5/4)

One printing press can print the whole school newspaper in 12 hours, while another press can print in 18 hours. How long will th

rusak2 [61]

Answer:

7 Hours 12 Minutes

Step-by-step explanation:

So they one of the printer increases at a rate of 1/12 and the other increases at a rate of 1/18. Since you don't know the time it actually takes, you will replace both numerators with and x. (x/12 and x/18). You want to set these up so that they are adding. (x/12 + x/18=1). Since you're adding, you want to change it to the same denominator. The lowest is 36 so you multiply x/12 by 3/3 (so you don't unbalance the equation) and x/18 by 2/2. You'll end up with 3x/36 + 2x/36= 1 which will simplify to 5x/36=1. Multiply each side by 36 to leave the variable by itself. It becomes 5x=36 and when you divide it by 5 you get 7.2. So it's seven and .2 hours, which is equivalent to7 and 1/5 of an hour or 7 hours and 12 minutes.
