Step-by-step explanation:

4(5y - 8 - 2) = 145 - 15 \\ 4(5y - 10) = 130 \\ 5y - 10 = 130 \div 4 \\ 5y - 10 = 32.5 \\ 5y = 32.5 + 10 \\ 5y = 42.5 \\ y = 42.5  \div 5 \\  = 8.5 \: or \: 8\frac{1}{2}

What is the value of the expression? Show all work.<br> -9 - 6 + 8 ÷ -4 * -2?
nadya68 [22]

Step-by-step explanation:

To do Order of Operations, we need to go with the order of the formula, PEMDAS.

P= Parenthesis

E= Exponents

M= Multiply (Whatever Comes First in Equation: M and D)

D= Divide

A= Addition (Whatever Comes First in Equation: A and S)

S= Subtraction

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

So, we need to start with parenthesis, there aren't any, so we move on to Exponents.

There are no Exponents either, so we start with division, then multiplication.

(We always have to go left to right).

So,

-9 - 6 + <u>8 / -4</u> x -2

-9 - 6 + <u>-2 x -2</u>

-9 - 6 + 4

Our problem is:

-9 - 6 + 4

We do subtraction, then addition. (Left to Right)

<u>-9 - 6 </u>+ 4

<u>-15 + 4</u>

-11.

Therefore, the answer is -11.

If q is the smallest composite number greater than 2 and p is the smallest prime number less than 10, what is p/q? a. 2 b. 0.5 c
Mrac [35]

Answer:

b. 0.5

Step-by-step explanation:

knowing that a prime number is an integer with exactly two divisors and a composite number is an integer with more than two divisors, we have that if q is a composite number greater than 2 these can be 4, 6, 8, .. But how the smallest of them should be is 4, and  p is a prime number can be 2,3,5,7,....

but  is the smallest prime number less than 10 then p=2, also p/q=2/4 = 0.5

Why is it valid to say that both a function and its inverse describe the same relationship
liberstina [14]
A comparison between a function and its inverse would show that the domain and range of the original function swap. The domain of the function becomes the range of the inverse, the range of the function becomes the domain of its inverse. 

Looking at ordered pairs of the function and its inverse would look like this:

(2,4) on the original function becomes (4,2) on the inverse. 

While the graph of a function and its inverse are noticeably different an important thing to note is that it is merely a reflection across the line y=x. 

So even though they appear different you are looking at the same relationship just as y vs. x instead of x vs. y
