Answer:
(-5,-1)
Step-by-step explanation:
2x+y=9 -> y=-2x+9
3x-y=16
3x-(-2x+9)=16
3x+2x-9=16
5x-9=16
5x-9 (+9)=16 (+9)
5x=25
x=5
no plug in 5 to x in any equation above
2(5)+y=9
10+y (-10)=9 (-10)
y=-1
so the answer is (-5,-1)
hope it's correct! and hope i helped
Please consider the attached graph.
We have been given that measure of angle 3 is 29°. We are asked to find the measure of angle 4.
Upon looking at our diagram, we can see that angle 3 and angle 4 are linear angles.
We know that linear angles add up-to 180 degrees, so the sum of measure of angle 3 and angle 4 will be 180 degrees.




Therefore, the measure of angle 4 is 151 degrees.
For this case we have the variable
:

Now, matching each expression with its value we have:
A goes with 4
B goes with 3
C goes with 2
D goes with 1
ANswer:
A goes with 4
B goes with 3
C goes with 2
D goes with 1
An infinite amount seeing as you can have infinite of each number
