check out the document I have uploaded, and the things I have done in blue; that's how you should show the inequality x>5/2

I have colored the right side because x is greater than 5/2, so instead of coloring the left side because if I color the left side it means that x is less but mow you get the inequality as x greater so you should color the side which increases

the left side means that it decreases

(I wanted to help you with the drawing since you already go help with solving and finding the inequality) Have a great day and I hope this helps

John is paid $35 plus 15% of his groups

lara [203]

The answer would be y=0.15x + 35 because 35 is like the base, the lowest he’ll pay, and then he’ll pay 0.15 which is 15% of the groups tips which is where the x comes in!

hope this helps!!

True or false is a relation in which each y value has only 1 x value

boyakko [2]

Answer:

The statement is true that a function is a relation in which each y value has ONLY 1 x value.

Step-by-step explanation:

The statement is true that a function is a relation in which each y value has ONLY 1 x value.

The reason is very clear that we can not have the repeated x-values (two same x-values).

For example, given the set of the ordered pairs of a relation

{(3, a), (6, b), (6, c)}

As the same x values (x=6) has two different Y values. Hence, the stated relation is not a function.

In order to be a function, a relation must have only 1 x-value for each y-value.

Therefore, the statement is true that a function is a relation in which each y value has ONLY 1 x value.

The price of a new car is $42,500. If the sales tax rate is 6%, what is the total cost for the car including tax?

ozzi

Answer: $45,050

Step-by-step explanation:

First we multipy 0.06 (6%) by 42,500

$42,500 * 0.06 = $2550

This is the tax that must be applied to $42,500

Now all we need to do is add $2,550to $42,500 and we get:

$42,500 + $2,550 = $45,050
