Answer:

Cost = 52.5n + 449.85

Step-by-step explanation:

Given

Cost = 3.5n + 29.99

Required

Determine cost of 15

Cost = 3.5n + 29.99

<em>The cost of 15 sweatshirts is calculated by multiplying the cost of 1 by 15.</em>

So, we have:

Cost = (3.5n + 29.99) * 15

Open Brackets

Cost = 3.5n  * 15 + 29.99 * 15

Cost = 52.5n + 449.85

<em>Hence, the simplified cost of 15 sweatshirts is</em>

Cost = 52.5n + 449.85

A system of linear inequalities is shown below.
Helga [31]
A) Isolate y in both inequalities

1) x + y ≥ 4 => y ≥ 4 - x
2) y < 2x - 3

B) Draw the lines for the following equalities:

1) y = 4 - x
2) y = 2x - 3

C) Shade the regions of solutions

1) The region that is over the line y = 4 - x
2) The region that is below the line y = 2x - 3

The solution is the intersection of both regions; this is the sector between both lines that is to the right of the intersection point, including the portion of the very line y = 4 - x and excluding the portion of the very line y = 2x - 3

Number 2 and please provide a step by step explanation!!!!
Alekssandra [29.7K]

The number of students in 5th grade is 60, since 24% of 250 is 60.

Since 90 is 38% if 250, 38 is going to be the percent of all students in sixth grade.

20% of 250 is 50, so the percent of all students in seventh grade is 50.

Finally, 45 is 18% of 250, so 18 percent of all students are in eight grade.

Hope this helped :)

17) f(x) = 16/(13-x).

In order to find domain, we need to set denominator expression equal to 0 and solve for x.

And that would be excluded value of domain.

13-x =0

Adding x on both sides, we get

13-x +x = x.

13=x.

Therefore, domain is All real numbers except 13.



18).f(x) = (x-4)(x+9)/(x^2-1).

In order to find the vertical asymptote, set denominator equal to 0 and solve for x.

x^2 -1 = 0

x^2 -1^2 = 0.

Factoring out

(x-1)(x+1) =0.

x-1=0 and x+1 =0.

x=1 and x=-1.

Therefore, Vertical asymptote would be

x=1 and x=-1

19) f(x) = (7x^2-3x-9)/(2x^2-4x+5)

We have degrees of numberator and denominator are same.

Therefore, Horizontal asymptote is the fraction of leading coefficents.

That is 7/2.


20) f(x)=(x^2+3x-2)/(x-2).

The degree of numerator is 2 and degree of denominator is 1.

2>1.

Degree of numerator >  degree of denominator .

Therefore, there would no any Horizontal asymptote.
