Answer:
Step-by-step explanation:
If the new height is 338m and the helicopter decended 127m to get to that new height then the original height is simply the sum of them both.
H = 338m + 127m
H = 465m
Answer:x-5
Step-by-step explanation:
In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.
<em>Multiply -4 and -3 in the function above.</em>
<em>Add 3 on both sides of the equation.</em>
<em>Add 2y on both sides of the equation.</em>
<em>Divide both sides of the equation by -3.</em>
Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.
Answer:
f(-3) = -5

Part A:
First we define the variable to be used for the problem:
x: the number of pages that Sandra should fax
The inequality for rent is:
0.06x <= 80
Note that the price will be less than using the fax from the office, since for the same number of pages, we have:
y = 0.10x
Answer:
an inequality that can be used to calculate the number of pages that Sandra should fax in a year is:
0.06x <= 80
Part B:
0.06x <= 80
From here we clear x:
x <= 80 / 0.06
x <= 1333.33333
Nearest whole number
x <= 1333
Sandra can use the leased fax for 1333 pages and the cost will be:
1333 * 0.06 = 79.98 $
Using the office fax the cost will be:
1333 * 0.1 = 133.3 $
Answer:
By renting the sara machine, you save:
133.3-79.98 = 53.32 $
