Answer:
x=2
Step-by-step explanation:
y=-x+5
-1(y)=(x+1)-1 = -y=-x-1
y=-x+5
+ -y=-x-1
0=-2x-4
0=-2x-4

What is a system of equations?A system of equations is a set or collection of two or more equations with the same variables. The common solutions are the intersecting points of the equations. The number of equations and unknowns affects the existence and uniqueness of the solution. A system of equations can be classified similarly to single equations.
Given that, the graph given shows a system of equations,
We know that, the solution of the system of equations, is given by the point where the lines intersect,
So, here the lines intersect, at (3, 2)
Therefore, the x-coordinate is 3
Hence, the x-coordinate of the solution to the system of equations is 3.

7.5 cups of sugar to make 14 dozen cookies. To the nearest hundredth, what is the rate of cups of sugar per cookie?
Answer:
0.54 There you go!
There are 168 cookies. 14 times a dozen (12) is 168.
The ratio of cups of sugar to cookies is 7.5 to 168.
If you want to find the cups of sugar you need for 168, divide 7.5 and 168 by 168.
168/168=1
7.5/168 is about 0.04.
The cups of sugar you use for one cookie is 0.04.
