Erin is making shirts for her upcoming family reunion. At the reunion she is selling each shirt for $18. If it cost her $30 to purchase the unfinished shirts, how much profit does she make if she only sells 25 shirts at the reunion?

Answer:

y = x + 5          

Step-by-step explanation:

1) First, find the slope of the line [tex]x-y = 4[/tex]. We can do this by setting it up in slope-intercept form, represented by the equation [tex]y = mx + b[/tex]. Whatever [tex]m[/tex] or the coefficient of the x-term is will be the slope. Isolate y in the equation:

[tex]x-y = 4\\-y = -x+4\\y = x -4[/tex]

So, the slope of the given equation is 1. Parallel lines share the same slope, thus the slope of the new line will be 1 as well.

2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula.

Since [tex]m[/tex] is the slope, substitute 1 for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, substitute the x and y values of (-6, -1) into those places as well. Then, isolate y in the resulting equation to put the equation in slope-intercept form and find the answer:  

[tex]y-(-1) = 1 (x-(-6))\\y + 1 = 1 (x + 6)\\y + 1 = x + 6\\y = x + 5[/tex]

a=m+30

Step-by-step explanation:

because you see that malik is always 30 points under, and A would be Alexia and M is Malik,

                                        The answer is a=m+30

Answer:

Lots of people are just answering to get free points now, they're not actually giving answers.

(and sorry if you miss the way it used to be).

Answer:

Put the equation into the form ax 2 + bx = – c.

Make sure that a = 1 (if a ≠ 1, multiply through the equation by. before proceeding).

Using the value of b from this new equation, add. ...

Find the square root of both sides of the equation.

Solve the resulting equation.

I assume the triangle is right angled

Answer:

70

Step-by-step explanation:

Okay so 10%=0.1. let's say that mystery number is x

that means that 0.1x=7

now to solve for x we need to multiply both sides of the equal sign by 10

so.....x=7*10=70

Answer:

  (x +3)(x +1)(x -2)

Step-by-step explanation:

A graphing calculator is a good tool for finding factors fast. Each zero (p) gives rise to a factor (x -p).

The graph shows zeros at -3, -1, and 2, so your factorization is ...

  (x +3)(x +1)(x -2)

Answer:the first one

Step-by-step explanation:

Answer:

1. P = 14cm; A = 10cm^2

2. P = 24cm; A = 12cm^2

3. P = 32cm; A = 63cm^2

4. P = 36cm; A = 80cm^2

5. P = 32cm; A = 60cm^2

6. P = 36cm; A = 81cm^2

7. P = 26cm: A = 30cm^2

8. P = 28cm; A = 49cm^2

9. P = 26cm: A = 42cm^2

Step-by-step explanation:

Formula to find perimeter for a rectangle:

length + width + length + width

l + w + l + w

Formula to find area for a rectangle:

length × width

l × w

1.

Perimeter (P): 5 + 2 + 5 + 2 = 14

Area (A): 5 × 2 = 10

2.

P: 6 + 2 + 6 + 2 = 24

A: 6 × 2 = 12

3.

P: 7 + 9 + 7 + 9 = 32

A: 7 × 9 = 63

4.

P: 10 + 8 + 10 + 8 = 36

A: 10 × 8 = 80

5.

P: 10 + 6 + 10 + 6 = 32

A: 10 × 6 = 60

6.

P: 9 + 9 + 9 + 9 = 36

A: 9 × 9 = 81

7.

P: 10 + 3 + 10 + 3 = 26

A: 10 × 3 = 30

8.

P: 7 + 7 + 7 + 7 = 28

A: 7 × 7 = 49

9.

P: 6 + 7 + 6 + 7 = 26

A: 6 × 7 = 42

Area will always have its units squared (cm^2) because the formula requires we multiply the numbers and therefore the units: cm × cm = cm^2
