Dmitrij [34]

Answer:

"The values for y are square roots of negative numbers"

Step-by-step explanation:

The steps shown are correct. But at the end we can see that we have to <em><u>"take the negative square roots"</u></em>.

This means we have to take the square root of -1. In the real number system, we CANNOT take the square root of any negative number. Hence, there is NO SOLUTION to the system.

2nd answer choice, "The values for y are square roots of negative numbers", is right.

The sum of three consecutive odd integers is − 87 . find the numbers.
DIA [1.3K]
Three consecutive odd integers are n, n+2 and n+4

n + n+2 + n+4 = -87
3n + 6 = -87
3n = -87 - 6
3n = -93
n = -93/3
n = -31

n+2 = -31 + 2 = -29
n+4 = -31 + 4 = -27

The numbers are -31, -29 and -27

Sam is an artist, and he wants to purchase frames to display his work at home. He wants to frame no fewer than 10 of his pieces,
Amiraneli [1.4K]

Answer:

The option D) 24x+18y=\dollar 225 and x+y^210 is correct

Step-by-step explanation:

Given that Sam is an artist, and he wants to purchase frames to display his work at home.

He wants to frame no fewer than 10 of his pieces, and he can spend a maximum of  $225. Large frames cost $24, and medium frames cost $18.

<h3>To find the system of inequalities can Sam use to determine the number of large frames, x, and medium frames, y, that he can purchase to meet his needs :</h3>

Let x be the large frames cost

Therefore x=\dollar 24

Let y be the medium frames cost

Therefore y=\dollar 18

Sam's Spend amount is \dollar 225

We can write the system of the given condition by

24x+18y=\dollar 225

x+y^210

<h3>Therefore the option D) 24x+18y=\dollar 225 and  x+y^210 is correct</h3>
