Answer 1

Answer:

Just to help you out in how to solve this just plug in every x of an equation -6, and in every y, -1. Plug these two number in every equation and see if it equal each other.Example:

y =4x +23

-1 = 4(-6) + 23

-1 = -24 + 23

-1 = -1

it shows that (-6,-1) is a solution to this equation

Letter A is one answer, let's see if you can find the others

Answer 2
The answer is A,C, D. That is because we have to substitute the values -6 for x and -1 for y in the equations given. We substitute the values and see if the answer is true

Michelle ordered 200 T-shirts to sell at the school carnival. She paid $2.80 per shirt, plus 5% of the total order for shipping. When she sells each T-shirt at the carnival, she adds 150% markup to the total price she paid for the shirt (including the cost of shipping). What is the selling price of each T-shirt? help i only have 10 points but plz help

Answers

Answer: 4.18$ or 4.19$ per shirt (I’m not entirely sure my answer is correct but do what you must with this info)

Step-by-step explanation: 200 times 2.80 is 560,

5% of 560 is 588,

150% of 588 is 882,

and then 882 divided by 200 is 4.18 (or 4.19)
