Answer:
-20
Step-by-step explanation:
multiply 5 and 6 then 5 and -10
30-50=-20
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!

Step-by-step explanation:</h3>
The area of a rectangular prism is the area of 6 surfaces. That is, 3 pairs of surfaces. Each of the three pairs will have one of the sets of dimensions ...
- length × width
- length × height
- width × height
In order for a net to be a net useful for calculating the prism surface area, it must have 3 pairs of rectangles with these dimensions. The description above matches that requirement.
___
Please note that no two surfaces with the same pair of dimensions are adjacent.
Answer:
b = +5
Step-by-step explanation:
8b^2=193+7
