Which facts could be applied to simplify this expression? Check all that apply.

The answer is B, C, and D. Like terms are terms with all the same variable, so 5x and -x are like terms.

C is correct. If we add -x to 5x, we get 4x. The other numbers remain unchanged because they have no like terms.

D is correct. Applying the rule of like terms, which is that like terms are numbers with the same variable, only add together numbers with the same variable.

Question 5 of 30<br> What is the period of the graph of y<br> 5cos(4x – 1) + 3?

Anastaziya [24]

Answer:

Period is $\frac{\pi}{2}$

Step-by-step explanation:

For the function $y=acos(bx-c)+d$ , the period is $\frac{2\pi}{|b|}$ .

Therefore, the period of the function is $\frac{2\pi}{|b|}=\frac{2\pi}{|4|}=\frac{2\pi}{4}=\frac{\pi}{2}$ .

What this means is that the function's wave cycle will repeat every $\frac{\pi}{2}$ units.

A volleyball curt is 61 feet lenght and 21 feet wide. How much rope will you use to mark the outline on the court?

lozanna [386]

So finding the rope is kind of like finding the perimeter. Add 61+61+21+21 and you will get 164 feet.

The Sommers invested $5000 for three years at 6.5%. How much interest did the investment earn in three years? What was the total

Jet001 [13]

Answer:

the interest is $975

the total amount is $5975

Step-by-step explanation:

lets use tje formula

I=PRT

where I is interest earned

P is the principal amount(original amount)

R is the rate of interest

and T is the time in years

the principal amount is 5000 since it is the original amount

rate is $\frac{6.5}{100}$ =0.065

time is 3 years

lets plug these values into our equation:

5000*0.065*3=I

5000*0.065*3=975

the interest is $975

the next part of the question is asking for the balance or the total amount which is principal+interest

5000+975=5975

the total amount or balance is $5975

hope this helps
