Answer:
The inverse of h(x) is 
Step-by-step explanation:
* Lets explain how to make the inverse of a function
- To find the inverse of a function we switch x and y and then solve
for new y
- You can make it with these steps
# write g(x) = y
# switch x and y
# solve for y
# write y as 
* Lets solve the problem
∵ 
# Step 1
∴ 
# Step 2
∴ 
# Step 3
∵
- Multiply each side by 5
∴ 5x = 2y + 6
- Subtract 6 from both sides
∴ 5x - 6 = 2y
- Divide both sides by 2
∴ 
# Step 4
∴ 
Answer:
b < -10 and (-∞, -10)
Step-by-step explanation:
I won't draw the number line but I will do the interval notation.
Interval notation is a way to describe infinite or finite sets with numbers.
To solve the inequality first add 2 to both sides to get:
-b > 10 Multiply both sides by -1:
b < -10 is the simplification of the inequality .
Now to write this in interval notation you need to know which direction the values are increasing, since b is less than -10, the values are going down starting from -10 (not including -10).
Interval notation: (-∞, -10)
20)
using
<span>a^3 + b^3 = (a+b)(a^2 − ab + b^2)
</span>so
w^3 + 125z^3
= w^3 +(5z)^3
= (w + 5z)(w^2 - 5wz + 25z^2)
hope it helps
