Answer: -2(f + 5)
Explanation:
Answer:
3
Step-by-step explanation:
So we have the function:

To evaluate the value of f(-2), substitute -2 for x. Thus:

Square first:

Multiply:

Now, subtract:

So:

And we're done!
748 student tickets were sold.
Step-by-step explanation:
Given,
Number of tickets sold = 1360
Revenue generated = $13328
Cost of each student ticket = $8
Cost of each non student ticket = $12
Let,
x be the number of student tickets sold
y be the number of non student tickets sold
According to given statement;
x+y=1360 Eqn 1
8x+12y=13328 Eqn 2
Multiplying Eqn 1 by 12

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 4

748 student tickets were sold.

Answer:
- fraction
- denominator
- product
- numerator
Step-by-step explanation:
When you multiply a <u>fraction</u> by a whole number, the denominator in the product is the same as the <u>denominator</u> of the fraction. The numerator in the product is the <u>product</u> of the whole number and the <u>numerator</u> of the fraction.

That's the rule. It is derived from the fact that multiplication indicates repeated addition.

Hey there! I'm happy to help!
All of the sides of a square are the same. Therefore, to find the area, you multiply the side by itself. Multiplying a number by itself is conveniently called squaring.
Doing this backwards is called finding the square root. If you have an area of 64, you square root it, showing you that the sides are 8.
This means the side length of our square rug is √99.
A rational number is one that can be written as a fraction of two integers. If you put √99 into your calculator, you get 9.949874371....
This is not a rational number because it goes on forever in no particular order, so we cannot write it as a fraction of two integers. The closest number we could use to have a rational square root would be 100, as its square root is 10.
Have a wonderful day! :D
