i need to find the inequality and make an equation to graph out of this : Carlos and Clarita want to sell T-shirts with dogs and cats on them. They’ve found two local t-shirt companies. Shirts R Us will charge them a one-time set up fee of $20 and $15/t-shirt. The second company, Tee4U, has a $50 set up fee and charges $12/t-shirt.
(I mean no need to waste points)
Answer:
Shirts R Us: 15t+20; Tee4U: 12t+50
If you're making a graph, shirts r us will start at (0,20) and will increase by 1 across and 15 up. tee4u will start at (0,50) and increase by 1 across and 12 up.

What is matter? Use elements in
your answer.
Answer:
Matter is anything that takes up space. All matter (aka everything) is made up of atoms. The air that we breathe is matter because it is made up of mainly oxygen atoms, but also other atoms as well. The air also takes up what we would call free space. A wooden desk is matter because it takes up space and is made of oxygen, carbon, nitrogen, calcium, and several other elements and atoms.

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; m∠p − m∠o = 90 degrees (alternate interior angles)

Which equation has the correct sign on the product?
A. (-9)(-9) = -81
B. (-12)(4) = 48
C. (31)(-10) = -310
D. (26)(3) = -78
Answer:
C. (31)(-10) = -310
Step-by-step explanation:
A. (-9)(-9) = -81
negative times a negative is a positive incorrect sign
B. (-12)(4) = 48
negative times a positive is a negative incorrect sign
C. (31)(-10) = -310
positive times a negative is a negative correct sign
D. (26)(3) = -78
positive times a positive is a positive incorrect sign
Answer:
C. (31)(-10) = -310
Step-by-step explanation:
This equation has the correct sign, because multiplying a positive number and negative number gives you a negative number.
The other answer choices have the wrong signs.
Multiplying 2 negatives together gives a positive, so A is wrong.
Multiplying a negative by a positive gives a negative, so B is wrong as well.
D is wrong because multiplying 2 positive numbers gives a positive number.
So, C is correct.

Which of the following best shows the associative property of addition?
a.4 + 5 = 9
b.(4 + 5) + 2 = 4 + (5 + 2)
c.4 + 5 + 2 = 2 + 5 + 4
Answer:
The answer is C: 4 + 5 + 2 = 2 + 5 + 4
Step-by-step explanation:
This is an example of the associative property of addition because the associative property of addition is described as any equation, that despite in what order your shift your equation to, the answer will stay the same. And as C shows, 4 + 5 + 2 will be rearranged to 2 + 5 + 4 and would still get the same answer, which would be 11.
The associative property of addition is represented by (4 + 5) + 2 = 4 + (5 + 2). The correct option is B.
What is associative property?
Rearranging the parenthesis in an expression will not change the outcome since some binary operations in mathematics have associative features.
The associative property is shown by the expression (4 + 5) + 2 = 4 + (5 + 2).
Solving the right-hand side:-
(4 + 5) + 2 = 9 + 2
(4 + 5) + 2 = 11
Solving the left-hand side:-
4 + (5 + 2) = 4 + 7
4 + (5 + 2) = 11
Therefore, the associative property of addition is represented by (4 + 5) + 2 = 4 + (5 + 2). The correct option is B.
