Answer: yes they are equivalent
Step-by-step explanation: rearrange the equation by subtracting what is to the right of the equation
Answer:
90
Step-by-step explanation:
45+45=90
90-180=90
every triangle's interior angles add up to 180.
Answer:
(2,16)
Step-by-step explanation:
y=-x+18
y=8x
8x=-x+18
8x+x=9x
-x+x=0
9x=18
9x/9=x
18/9=2
x=2
y=8(2)
y=16
So x should be equal to -2 when you equal them to each other.
ANSWER
The x-coordinate of the solution to the system of equations is 3.
EXPLANATION
The solution to the system of equations is the point of intersection of the straight lines that represents the given system.
From the graph the two straight lines intersected at:
(3,2)
Hence the solution to the system of equations is (3,2)
The x-coordinate of the solution to the system of equations is 3.
