Y=1/2x+4 and 2y+4=x so substitute y into the second equation to get
2(1/2x + 4) =x
use the distributive property to get x + 8 = x. There is no solution to this equation because x + 8 cannot equal x, and because of this you cannot solve the rest of it so there is no solution.
Answer:
85 cm
Step-by-step explanation:
Hello.
is a quadratic function, because it has an 
(x squared, or x times x) term.
Here's what linear functions look like:
A graph of a linear function is a line.
Quadratic functions look like so:
A graph of a quadratic function is a parabola.
Therefore, the given function is a quadratic function.
I hope this helps.
Have a nice day.
1cm is equal to 10mm, so 37cm is the same as 370mm
1cm is equal to 0.01m, so 37cm is the same as 0.37m
Add the two equations:
2x + 4y = 16
-2x - 3y = -6
2x + -2x = 0
4y -3y = y
16-6 = 10
When you add the equations you get y = 10
Now you have a value for y, use the first equation to solve for x:
2x + 4(10) = 16
2x + 40 = 16
Subtract 40 from both sides:
2x = -24
Divide both sides by 2
X = -12
Answer: x = -12 and y = 10
