Hello!
Since we already see an equation that equals y (-2x-4), we can plug that equation into the first to solve for x.
x+4(-2x-4)=19
x-8x-16=19
-7x=35
x=-5
Now that we know the value of x, we will plug it into the second equation to solve for y.
y=-2(-5)-4
y=10=4
y=6
This gives us the answer below
The correct answer is A) (-5,6)
I hope this helps!
Answer: This is a guess I am not that smart

Answer:
e/g+f/g
Step-by-step explanation:
(e+f)/g can be split up. e/g+f/g is equal to (e+f)/g so your answer is e/g +f/g
Answer:
1/4 feet long should each pieces be.
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1 such as 3 miles per second or 4 km per hour
As per the statement: Becky has a board that is 2 and 3/4 feet long.
⇒ Length of a board =
feet
Also, she need to cut the board into 11 pieces.
by unit rate definition:
![\text{Unit rate per pieces} = \frac{\frac{11}{4} }{11}](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20rate%20per%20pieces%7D%20%3D%20%5Cfrac%7B%5Cfrac%7B11%7D%7B4%7D%20%7D%7B11%7D)
or
![\text{Unit rate per pieces} = \frac{11}{4} \times \frac{1}{11} = \frac{1}{4}](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20rate%20per%20pieces%7D%20%3D%20%5Cfrac%7B11%7D%7B4%7D%20%5Ctimes%20%5Cfrac%7B1%7D%7B11%7D%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
Therefore, 1/4 feet long should each pieces be.
