Hi there!
x - 3y = 9
x = 9 + 3y
-4x + y = 8
-4(9+3y) + y = 8
-36 - 12y + y = 8
-36 - 11y = 8
-11y = 44
-y = 4
y = -4
x - 3y = 9
x - 3(-4) = 9
x + 12 = 9
x = 21
So, your answers are y = -4 and x = 21.
Hope this helps!

Answer:
y = 1/2x
Step-by-step explanation:
The x seems to double the size of the y on the points.
Answer:
Answer:
33.14\°
Step-by-step explanation:
Let
Y ----> field of vision that Yash's camera would need
we know that
Applying the law of sines
\frac{sin(Y)}{25}=\frac{sin(41\°)}{30}
Solve for sin(Y)
sin(Y)=\frac{sin(41\°)}{30}(25)
Y=sin^{-1}[\frac{sin(41\°)}{30}(25)]
Y=33.14\°
If the total age of both April and Amy are 53
And Amy is 9 years younger than april.
Then to solve for Amy's age you would subtract 9 from 53 and divide by 2
which equals 22
Since amy is 9 years younger than April, then April's age is Amy's age 22 + 9 which gives you 31
April's age is 31 and Amy's age is 22
