Answer:

x = -20, y = -2

Step-by-step explanation:

8y - x = 4

x = 8y - 4

2x - 21y = 2

2(8y - 4) - 21y = 2

16y - 8 - 21y = 2

-5y = 10

y = -2

x = 8(-2) - 4

x = -20

The two inequalities that represents the constraints for the art studio classes per week are:

x + 1.5y = 40

35(x + y)  > 1,000

<h3>What two inequalities represent the constraints?</h3>

Here are inequalities signs and what they mean:

> means greater than

< means less than

≥ means greater than or equal to

≤ less than or equal to

= means equal to

The inequality that represents the total hoursthe art studio is open would be an equal to sign. This is because the store is open for a maximum of 40 hours.

The inequality that represents the total earnings would be represented with a greater than sign because the studio earns more than $1000 weekly.

Solve the system <br> x+3y=5 <br> x+4y=6<br><br> A) (2,1)<br> B) (1,5)<br> C) (8,-1)<br> D (11,-2)
pochemuha
So you have the equations
x + 4y = 6
x + 3y = 5
Subtract the two equations.

You get y = 1.
The only answer with a value of y = 1 is A

A is your answer.
Have a nice day! :)
