Answer:
49.5 meters of linen were left after the sale.
Step-by-step explanation:
Given that there are 100 meters of linen
And 15.75, 22.50 and 12.25 meters are sold.
This means that the sold linen has to be added to find the total linen sold.
And then the quantity of sold linen will be subtracted from 100 to find the meters of linen left.
Left linen will be:
Hence,
49.5 meters of linen were left after the sale.
The function range of {y|y ≤ 5} is f(x)=-(x-4)^4+5.
Since the range has less than a sign, this means that the parabola is
facing downwards and it means that a is negative.
The range is given by
Since the range is
This means that k = 5 , and since a is negative
The correct function is

Answer:
Four-door sedan = 22
Two-door coupes = 6
Step-by-step explanation:
This is an algebra problem.
Let "<em>x</em>" represent number of four-door sedan,
"<em>y</em>" represent two-door coupe.
Since there are total of 28 autos on which film is applied, we have:
<em>x</em> + <em>y</em> = 28 Equation 1
<em>y </em>= 28 - <em>x </em>Equation 2
Also provided,
Total revenue = $3,459.72
That means,
129.99<em>x </em>+ 99.99<em>y</em> = 3,459.72 Equation 3
Putting value of "<em>y</em>" from Equation 2 in Equation 3 we have:
129.99<em>x</em> + 99.99(28 - <em>x</em>) = 3,459.72
129.99x + 2,799.72 - 99.99<em>x</em> = 3,459.72
30<em>x</em> = 660
<em>x </em>=
Therefore, number of four door sedans = 22
Further <em>y</em> that is two door sedan = 28 - <em>x = </em>28 - 22 = 6
