Answer:
x>-9
Step-by-step explanation:
The given inequality is :
-3x - 7 < 20
We need to find the solution of the inequality using graph.
-3x - 7 < 20
Add 7 to both sides
-3x-7+7 < 20+7
-3x <27
x>-9
Hence, the attatched graph shows the solution of the given inequality.
Answer:
f(x)^-1 = x - 4
D: {x is all real numbers}
Step-by-step explanation:
change f(x) to y
switch x with y and vice versa
solve for y
Let's assume length of the room as y
so the width of the room = y - 5
Area
y * (y - 5) = 750
These are called integer numbers.
We start with natural numbers (or whole numbers), i.e. the set

When you add the opposite of each whole number, you have the set of integers:
