2x + -1y = 9
Solving
2x + -1y = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
2x + -1y + y = 9 + y
Combine like terms: -1y + y = 0
2x + 0 = 9 + y
2x = 9 + y
Divide each side by '2'.
x = 4.5 + 0.5y
Simplifying
x = 4.5 + 0.5y
Hope this helps :)

The formula for area of a square is Area = side^2.
You are given the area, so now you have 97,818 = Side^2.
To find Side, take the square root of both sides:
Side = √97818
Side = 312.76 miles.
Rounded to the nearest mile is 313 miles.
Answer:
h(-8)=1 and -12
Step-by-step explanation:
In this problem, we will need to plug in "-8" for any x we see.
h(-8)=|-8+4|-3
h(-8)= |-4|-3
h(-8)=4-3
h(-8)=1
Yay! We got an answer. However, since there is an absolute value, there is another case -- if x is negative.
h(-8)=-8-4
h(-8)=-12
Answer: (C) 4
<u>Step-by-step explanation:</u>
The corresponding sides of a 30°-60°-90° triangle are: b - b√3 - 2b
The side corresponding to 90° is 8 = 2b --> b = 4
The side corresponding to 30° is y = b <em>as stated above, b = 4</em>, so y = 4
