Answer:
x = -3.5
Step-by-step explanation:
1(x-2) = -5.5
x-2 = -5.5
+2 +2
x = -3.5
((-9+14)/2, (-20+12)/2)
(5/2,-8/2)
(5/2,-4)
the x and y values makes both equations true
Explanation
a linear system is the set of 2 linear equations.
Step 1
the solution to a linear system is the coordiante where the line intersect, this coordiante satisfies both equations, then
the x and y values makes both equations true
Step-by-step explanation:
y=(x-d)²+7
y-7=(x-d)²
√(y-7)=x-d
d=x-√(y-7)

The price per square foot is 0.55$
Step-by-step explanation:
We can solve this problem by applying the rule of three.
In fact, we know that:
- The price per 1 gallon is $55
- The area covered by 1 gallon is 
So this means that the price per
(1 gallon) is $55.
Here we want to find the price per square foot, so we can write:

And solving for x, the price per square foot, we find:

So, the price per square foot is 0.55$.
