Answer:
6
Step-by-step explanation:
Answer:
the x-intercept is found when 0 is put into the equation for y.
Because the x-intercept is found when the function passes through the x-axis.
x+2y=5
x=5
So x=5, y=0, the point would be (5,0).
Answer:
x = 4
y = -1
z = 3
Step-by-step explanation:
Let 1st number = x
Let 2nd number = y
Let 3rd number = z
x+y+z=6
x+y=z
x=z+1
(Apply Simultaneous Equations)
Hence:
z+z=6
2z=6
z=6/2
z=3
Now:
x+y=3
x=3+1
x=4
Now:
4+y=3
y=3-4
y=-1
Well the range is the maximum minus the minimum number so the range for highlands is 32 and the range for the lowlands is 28
