Step-by-step explanation:
A linear graph is any straight-line graph. That's a straight line.
Answer:
B
Step-by-step explanation:
3√x+2 = √x+4
divide both sides by 3
√x+2 = √x+4 / 3
remove radical by squaring both sides
x+2 = x+4/9
x+2 = x/9 + 4/9 =
8x/9 = -14/9
8x*9 = -14*9=
72x = -126
x = -7/4
X = D/(1 - h)
1 - h = D/x
h = 1 - D/x
D = 400, X = 4000
h = 1 - 400/4000
h = 1 - 0.1 = 0.9
