There are 5280 feet in a mile
45 * 5280 = 237600
there are 3600 seconds in an hour (60 minutes time 60 seconds)
so we have 237600 feet in 3600 seconds
237600 / 3600 = 66 feet per second.
Answer:
B. 2x + 5, with the restriction x ≠ five over 2
Step-by-step explanation:
The given expression is the difference of squares, so factors as ...
the product of the quantity 2x plus 5 and the quantity 2x minus 5 over the quantity 2x minus 5
You will note that the numerator and denominator have a common factor:
the quantity 2x minus 5
Factoring that out gives ...
2x + 5, with the restriction x ≠ five over 2 (x is restricted from being a value that makes the denominator zero.)

<em>Comment on the form of the answer</em>
Since you have written your math expressions using words instead of symbols, we assume you can read them more easily that way. So, we have provided the explanation in the form you can most easily understand. (Personally, I prefer math symbols. They are more compact and tend to be less ambiguous.)
Answer:
Your in Pacyber aren't you? Mr. Breux class? Anyway the answer is (0,-4)
Step-by-step explanation:
The y intercept is (0,-4)
Answer:
1
Step-by-step explanation:
1) First, place the given equation in slope-intercept form (
format) to find its slope easier. Isolate the y:

So, the equation of the line in slope-intercept form is
. When an equation is in slope-intercept form, the
, or the coefficient of the x-term, represents the slope. Thus, the slope for the given line would be -1.
2) Lines that are perpendicular have slopes that are opposite reciprocals of each other. We need to find the opposite reciprocal of -1, then.
To find the opposite reciprocal of a number, write the given number as a fraction first -- making -1 be written as
-- then switch the sign and flip the numerator and denominator. So, the opposite reciprocal of -1 is 1, and 1 is the slope of the perpendicular line.
68 is not a prime number. The prime factorization of 68 would be 2 x 2 x 17.
