If f(x) = x + 4 and g(x) = x, what is (gºf)(-3)?

Mathematics

(gºf) means solve f(x) first, then use that for g(x)

In the equation for f(x) replace x with -3:

f(x) = x +4 = -3 +4 = 1

Now replace the x in the equation for g(x) with 1

g(x) = x = 1

Set of integers x such that x - 5 ​
My name is Ann [436]

The set of integers that satisfy the inequality is x ∈ (-∞, 30) where x is an integer.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

The question is incomplete.

The complete question is:

Set of integers x such that x - 5 is less than 25​.

We have an inequality:

x - 5 < 25

Adding 5 both sides:

x - 5 + 5 < 25 + 5

x < 30

x ∈ (-∞, 30) where x is an integer.

Thus, the set of integers that satisfy the inequality is x ∈ (-∞, 30) where x is an integer.

A CD player is on sale for $90 at an electronics store. If the original price was $125, what was the percent of discount
krek1111 [17]
This is the working of how it is 28% discount

Find the amount of discount : $125 - $90 = $35
Divide by the original price : $35/125 = 0.28
Change in to percentage : 0.28 x 100 = 28%

Therefore the percentage discount is 28% off

Bill can hit a bucket of 323 gold balls in 17 hours.
yanalaym [24]
It is important to clearly understand all the important information's already given in the question. Based on those details the answer to the question can be easily determined.
In 17 hours the number of golf balls hit by Bill = 323
Then
In 1 hour the number of golf balls hit by Bill = (323/17) * 1
                                                                     = 19
So
The number of golf balls hit by Bill in 23 hours = 23 * 19
                                                                          = 437
So 437 balls will be hit by Bill in 23 hours. I hope the procedure is clear enough for you to understand. This procedure will help you to solve similar problems in future without requiring any outside help.
