Find the domain and range of the relation, and determine whether it is a function.

1 answer:

7 0

The domain is all the x values so {2,-4, 1, 2, -1}
The range is all the y values so {1, 5, 7, -3, 2}

Yes, it is a function because each item in the domain matches one item in the ranges.

I need help. how do i write 4=(-8)+3x as a decimal

Vanyuwa [196]

This is an equation, you can't write equations as decimals. I think you're asking for x (as a decimal)?

Add 8 to each side: 4+8= 8+(-8)+3x
12=3x
x=4
This is a whole number so it's already in decimal form

No Alan did not break even

Alan incured a loss of 6.25 %

<em><u>Solution:</u></em>

Given that,

Alan bought two bikes

He sold one to Beth for $300 taking a 25% loss

He also sold one to Greta for $300 making a 25% profit

When a person sells two similar items, one at a gain of say x%, and the other at a loss of x%, then the seller always incurs a loss

Which is given as:

$loss\ \% = (\frac{x}{10})^2$

Here, x = 25

$loss\ \% = (\frac{25}{10})^2\\\\loss\ \% = 2.5^2\\\\loss\ \% = 6.25$

Thus the loss percentage is 6.25 %
