Answer: At point (
)
Step-by-step explanation: <u>Diagonal</u> is a line uniting two opposite points. In a square, the diagonals intersect in a 90° and bisect each other, i.e., divides each diagonal into two segments of the same length.
In other words, the diagonals of a square meet at their midpoint, which is found as the following:
(x,y) = 
The opposite vertices of the given square are (-2,6) and (1,-7).
So, the intersection is
(x,y) = 
(x,y) = 
The diagonals of square with vertices (-2,6)(6,1)(1,-7)(-7,-2) intersect at point .
Answer:
The width of the room is 17.25 feet
Step-by-step explanation:
2(15.75+W)=66
Divide both sides by 2: 15.75+W=33
Subtract 15.75 from both sides: W=33-15.75=17.25

Answer:
f(3)=3/7
Step-by-step explanation:
Answer:
The solution is (2,6)
Step-by-step explanation:
Let
x-----> the number of hours to change a fuel injection unit
y-----> the number of hours to change a transmission
we know that
5x+10y=70 -----> equation A
8x+8y=64 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2,6)
see the attached figure
