Answer:
.8
Step-by-step explanation:
.8 when turned into a percentage becomes 80%
.8/1 = %80
78% is less than %80
For this case we have the following linear equation:
As the lines are perpendicular, then the slope of the line is:
Where,
m: is the slope of the original line
Substituting values we have:
Rewriting:
Then, the equation in point-slope form is given by:
Where,
(xo, yo): ordered pair that goes through the line.
Substituting values we have:
Answer:
an equation in point-slope form for the line perpendicular to y = –2x + 8 that passes through (–3, 9) is:
60/15 is 4
16/4 is 4
in 15 minutes, he or she runs 4km
4 times .621 is about 2.5 miles

Answer:
is the answer
given the function .
Step-by-step explanation:
is the given function.
I'm going to do some examples of plugging in because that is what this problem is asking you to do.
Example 1: What is f(2)?
f(2) means we are going to replace x with 2 in the thing we called f:
Example 2: What is f(-2)?
f(-2) means we are going to replace x with -2 in the thing we called f. Before we do this I just wanted to tell you something here about negative numbers or expressions. When plugging in either of these, use ( ) around the number you are plugging in. So I should re-say my first line here.
f(-2) means we are going to replace x with (-2) in the thing we called f:
.
Example 3: What is f(cat+tuna)?
f(cat+tuna) means we are going to replace x with (cat+tuna) in the thing we called f:
To expand the top, we are going to use this formula for squaring a sum:
.
Ok let's move on to the true problem:
f(x+h) means to replace x with (x+h) in the thing we called f:
This is really the same problem we had above except without the cat and the tuna but with x and h respectively instead.
3.14 is the answer
