Answer:
20
Step-by-step explanation:
f(x) = x + 10
Replace f(x) with y.
y = x + 10
Now, remember that in an inverse function you flip the x and y, so
x = y + 10
Solve for y
y = x - 10
because it's 2x... we must multiply by 2.
2y = 2x - 20
Original equation:
h(x) = 2x - 0
h(x) is 2y..
D.
Answer:
4
Step-by-step explanation:
slope (M) = (y2-y1)/(x2-x1)
x1 =3, y1= -5, x2 = 5, y2=5
= (-5-5) / (3-5) = -10/-2 = 5
M=5
Answer:
Step-by-step explanation:
Given that Heights of 10-year-olds, regardless of gender, closely follow a normal distribution with a mean of 55 inches and a standard deviation of 6 inches.
If X is height then X is N(55,6)
Z score would be 

b) 
c) Tallest 10% z = 1.28
X score =
inches
d)
i.e. 16.37% cannot go on this ride.
30b³ + 20b² + 15b + 10 = ...(:5)
6b³ + 4b² + 3b + 2 =
6b³ + 3b + 4b² + 2 =
3b(2b²+1) + 2(2b²+1) =
(2b²+1)*(3b+2)
