I think it makes it more easier if you simplify the inequality.
4x + 20 < 40 First subtract 20 on both sides
4x + 20 - 20 < 40 - 20
4x < 20 DIvide 4 on both sides to get the variable "x" by itself
x < 5 [x is less than 5, so x represents the numbers that are less than 5]
[Note:
If the sign is < or >, you use an open circle.
If the sign is ≤ or ≥, you use a closed circle.]
Your answer is the 1st option because the solution is any number that is less than 5
Answer:
<em>it is False</em>
Step-by-step explanation: <em>i also did this test </em>
Answer:
12
Step-by-step explanation:
2 : 6 pencil : eraser
? : 36
36 divided 6 = 6
so to get to the unknown value u multiply 2 x 6
which equals 12
Option A
If f(x) =
and g(x) =
then 
<em><u>Solution:</u></em>
Given that f(x) =
and g(x) = 
To find: (f - g)(x)
We know that,
(f – g)(x) = f (x) - g(x)
Let us substitute the given values of f(x) and g(x) in above formula,

For solving the brackets in above expression,
There are two simple rules to remember:
When you multiply a negative number by a positive number then the product is always negative.
When you multiply two negative numbers or two positive numbers then the product is always positive.
So the expression becomes,

Combining the like terms,

Thus option A is correct
