Evaluate the function when x=5 F(5)=?

Mathematics
1 answer:
kenny6666 [7]2 years ago
7 0

Step-by-step explanation:

When evaluating piecewise function, make sure the x value satisfies the function we use.

since 5>3, we use the second equations

That function is a constant function, this means at any x>3, exclusive, we will have a y value of -1.

So

f(5) =  - 1

Is 5 in the solution of x+3>8?
Ivan

Answer: D) No; If x is 5, the expression on the left simplifies to 8, making the inequality false.

In other words, if x = 5, then x+3 becomes 5+3 which ultimately becomes 8, but this is not greater than 8 on the right side.

Your steps could look like this

x+3 > 8

5+3 > 8 ... replace x with 5

8 > 8 ... this is a false inequality

Phoebe is concerned that it the error is not fixed, her pay increase wll be less in future
SSSSS [86.1K]

The difference in the pay rate of Phoebe in 5 years will be $11850

<h3>How to calculate the pay? </h3>

Your information is incomplete. Therefore, an overview will be given. Let's assume that the pay rate is $20000. When there is a 5% increase, the new pay rate will be:

= $20000 + (5% × $20000)

= $20000 + $1000

= $21000

When there is $0.75 increase per hour, the new pay rate on 5 years will be:

= (0.75 × 43800)

= $32850

The difference will be:

= $32850 - $21000

= $11850
