Answer:
x = -8
Y = -11
Step-by-step explanation:
Given
Y = 3x + 13
Y = x - 3
Substitute x - 3 for Y in the first equation
We have
Y = 3x + 13
x - 3 = 3x + 13
Add 3 to both sides
x - 3 + 3 = 3x + 13 + 3
x = 3x + 16
Subtract 3x from both sides
x - 3x = 3x - 3x + 16
-2x = 16
Divide both sides by -2
x = 16/-2
x = -8
Now substitute -8 for x in any of the above equations to get Y.
Using the second equation, we have
Y = x - 3
Y = -8 - 3
Y = -11

Answer:
There are 8 boys in the chorus and 16 girls in the chorus
The graph in the attached figure
Step-by-step explanation:
Let
x----> the number of boys
y----> the number of girls
we know that
-----> equation A
----> 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 (8,16)
see the attached figure
therefore
There are 8 boys in the chorus
There are 16 girls in the chorus
Answer:
It is 102
Step-by-step explanation:
Answer:
Step-by-step explanation:
If you use the triangle inequality theorem you just add the first two sides to determine if the number is bigger than the third side if so it can form a triangle that's the first step. Just repeat with a b and c a+b a+c and b+c, and it will help you determine what type of triangle it is.
I believe the first set can, angle a and c are larger than angle b I can't be sure about the other one. I'm sorry I hope this helps push you some direction forward.
