What characteristic is true for all relations that are functions
Ilia_Sergeevich [38]

Answer: First option, the graph of the relation passes the vertical line test.

Step-by-step explanation:

A function is a relation that maps elements from a set (the domain, the x-values) into elements from another set (the range, the y-values)

Where the only condition we have is that each element from the domain can be mapped into only one element from the range.

So if we draw a vertical line at any point of the graph, it can intersect the graph of the function a maximum of one time. (this is known as the vertical line test)

Then the correct option is that the graph of the relation passes the vertical line test.

Veronica has two offers for a $65,000 student loan. The first loan has a 6.3% interest rate for 15 years, and the second loan ha
steposvetlana [31]

The second option has a lower amount of interest paid.

In order to determine the loan option that minimizes loan payment, the future value of both loan options has to be determined.

FV = P (1 + r)^nm

FV = Future value  

P = Present value  

R = interest rate  

m = number of compounding

N = number of years  

<em><u>First loan option </u></em>

65000( 1 + 0.063/12)^300 = 312,707.21

<em><u>Second loan option </u></em>

65000( 1 + 0.048/12)^240 = 169,435.51

You are trying to recreate flubber because you are obsessed with that movie and you thought it was the coolest. you take 70% sli
german

Let x be the amount (gal) of the 40% slime solution you end up using. You want to end up with 120 gal of the 50% solution, so that you would use 120-x gal of the 70% solution.

You want the final solution to consist of 50% slime, or 60 gal of slime. Each gal of the 40% solution contributes 0.4 gal of slime, while each gal of the 70% solution contributes 0.7 gal of slime. This means

0.4x+0.7(120-x)=0.5\cdot120=60

\implies0.4x+84-0.7x=60

\implies24=0.3x

\implies x=80

so the answer is B.
