Answer:
(3,1) because x is 3 and y is 1.
Step-by-step explanation:
x+2y=5
3x+5y=14
Multiply first equation by 3:
3x+6y=15
3x+5y=14
Subtract 3x:
1y=1
Therefore, y = 1
Plug it back into 1st equation:
x+2(1)=5
x+2=5
Therefore, x = 3
Judging from your answers, it looks like (3,1) because x is 3 and y is 1.
I hope this helped!

Hello!</h2>
The answer is: The Anya's drawing is 6 inches long.
Have a nice day!
<h2>Why?</h2>
To solve this problem, we need to consider the drawing's length with respect to the actual bug's size, so, the scale factor is:
So, how long is Anya's drawing of the bug?
We can find it, using the following equation:
Hence, the Anya's drawing is 6 inches long.
Have a nice day!
Answer:
6
Step-by-step explanation:
Hope thats the correct answer.
X^2 + 18x + 7 = 0
x^2 + 18x = -7
x^2 + 18x + 81 = -7 + 81....add 81 to both sides
(x + 9)^2 = 74
x + 9 = sqrt 74
x = -9 (+-) sqrt 74
x = -9 + sqrt 74
x = -9 - sqrt 74
the reason u add 81 to both sides.....u take half of the x term, then square it.
half of 18 is 9....9^2 = 81
