Answer:

D

Step-by-step explanation:

to find the zeros, equate f(x) to zero, that is

(x - 7)(x + 8) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x + 8 = 0 ⇒ x = - 8

HOW SHOULD I DO WORK... HELP!!!!!
Angelina_Jolie [31]

Answer: You should create number line since it's a inequality question, so it would make sense. But In my opinion I don't think you need to show your work unless it tells you to. So that's why I'm telling you that you can show work, which is by making a number line.

* I hope this helps:) Mark  me the brainliest:)!!

Translate and solve 5 less then three times a number is 16
Sergeu [11.5K]

Answer:

the number is 7

Step-by-step explanation:

I am not sure what you mean by "translate" but here is my solution to the problem.

first write the question as a equation: 3x - 5 = 16

then add 5 to both sides: 3x = 21

divide both sides by 3: x = 7

double check

3*7 - 5 = 16

the number is 7

If enrollment increases by approximately the same
Tanya [424]

Given:

The enrollment increases by approximately the same percentage between 2000 and 2010 as it decreased between 1950 and 1960.

To find:

The expected enrollment in 2010.

Solution:

Percentage decrease formula:

\%\text{ decrease}=\dfrac{\text{Initial value - New value}}{\text{Initial value}}\times 100

The percentage decrease in between 1950 and 1960 is:

\%\text{ decrease}=\dfrac{4-3.5}{4}\times 100

\%\text{ decrease}=\dfrac{0.5}{4}\times 100

\%\text{ decrease}=\dfrac{50}{4}

\%\text{ decrease}=12.5

The enrollment decreased by 12.5% between 1950 and 1960. So, the enrollment increases by 12.5% between 2000 and 2010.

The expected enrollment in 2010 is:

\text{Expected enrollment}=7+\dfrac{12.5}{100}\times 7

\text{Expected enrollment}=7+0.875

\text{Expected enrollment}=7.875

Therefore, the expected enrollment in 2010 is 7.875 thousands.

Find an angle α that is coterminal with an angle, in radians, measuring −13π/2, where 0≤α<2π. Give your answer as an exact an
Oliga [24]

Answer:

  α = 3π/2

Step-by-step explanation:

To find the coterminal angle, add multiples of 2π until you have an angle in the desired range. Here, you need to add 8π.

  α = -13π/2 + 8π = (-13 +16)π/2 = 3π/2
