Based on the Pythagoras theorem, where a and b are the legs of the triangle and c is the hypotenuse.
Therefor x =
Answer:
Slope: 6
Y-intercept: 0
Proportional
Step-by-step explanation:
The equation for this table is y = 6x + 0 or just y = 6x.
y = 6x + 0
y-value slope (x-value) y-intercept
Proportional because it crosses (0,0) on the graph.
Answer:
Your answer would be x+y=531 and y=2x
Step-by-step explanation:
We know that Nancy bought 531 shirts and that some are long sleeved and some are short sleeved. Since x represents the long sleeved shirts and y represents the short sleeved shirts, x+y=531. We also know that there are twice as many short sleeved shirts as long sleeved shirts. So, y=2x.

Answer:x=2, y=1, z=-1
Step-by-step explanation:
Given
2x+y+z=4----1
x-y+3z=-2----2
-x+y+z=-2----3
Add 2 & 3 we get
4z=-4
z=-1
Put value of z in 1 & 2
2x+y-1=4
2x+y=5----3
x-y+3(-1)=-2
x-y=1------4
add 3 & 4 we get
x=2
Put x & z in 1
y=1
