First plug in 2 for r like so:
-9(2) - 7
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
First we have multiplication:
-9(2) - 7
-9(2) = -18 <<< When multiplying a negative and positive number together you will multiply normally and the answer will have a negative sign
-18 - 7
Now for the subtraction:
-18 - 7 <<< When subtracting with a negative number you will do something called "Same-Add-Opposite." This means that you will keep the first number in the expression (in this case that is -18) the same. Then turn the subtraction sign into an addition sign. Finally you will take the "opposite" sign of the second number. When I say "opposite sign" I mean that if this number is positive it will become negative. If it was negative it will become positive.
Here is your expression after applying same - add - opposite:
-18 + (-7)
-25
Hope this helped!

Answer:
14.25
Step-by-step explanation:
5ft is 60in.
60-31.5=28.5
28.5/2=14.25
14.25 on each side
Step-by-step explanation:
you only need to provide an example ?
if your question here is complete, then the full set is
{1,7,8}
and these are all possible subsets (pick any one you like) :
{1}, {7}, {8}, {1,7}, {1,8}, {7,8}
and formally also
{}, {1,7,8}
the empty set is a subset of every set, and the whole set itself is also formally a subset.
<u>Given</u>:
Given that the graph of a function f(x).
We need to determine the value of f(0)
<u>Value of f(0):</u>
Let us use the graph to determine the value of f(0)
The value of f(0) is the value of f(x) when x = 0.
Hence, from the graph, we need to find the value of f(x) when x = 0
Thus, when x = 0, the value of f(x) is also 0.
Therefore, we have;
f(0)=0
Thus, the value of f(0) is 0
Hence, Option c is the correct answer.
