The nickles and dimes are worth 13.90 
<span>Since nickles are worth 5 cents and dimes worth 10 cents, we'll take the number of nickles, x and multiply by 5, and likewise the number of dimes, y and multiply by 10. Since we are using cents, we'll convert 13.90 to cents by moving the decimal two places.and making it 1390 </span>

<span>5x + 10y = 1390 </span>

<span>There are 196 coins. </span>
<span>When counting them we'll just take the number of nickles, x, and add them to the number of dimes, y. </span>

<span>x+y=196</span>

fiasKO [112]

The price per ticket, excluding the convenience charge, is  $65.

<h3>How to solve for the privce per ticket</h3>

the rush delivery is given as $15.

The total cost of the tickets is said to be put at $352.50

Then the value that we would have for the the 5 tickets wpould be 352.50 - 15 = $337.50.

There is the convenience charge of $2.50 per ticket. This charge is excluded from the convenience charge that is to be paid.

Hence you would have to make the payment of

337.50 - 5*2.50

= 325.

Next we are to solve for the price of the ticket whioch is independent of the convenience charge

= 325 / 5

= $65

Hence the price per ticket is given as 65 dollars

Is a vertical line a function
topjm [15]

Answer:

No

Step-by-step explanation:

Explanation 1)A vertical line can be represented by the equation x=a, where a can be any number. If you think about it, there is no y in the function, this making it not a function.

Explanation 2) For a line to be a function it has to pass the vertical line test, so you will draw a vertical line through the function and if it touches more than one point then it is not a function. In this case if you draw a vertical line through a vertical line there are an infinite number of places where the lines intercept, so it is not a function.

PLEASE HELP I'LL MARK YOU BRAINLIEST IF YOU'RE CORRECT I don't understand this​

The y-intercept of the function is at y = -3 so the options that don’t include it are off the table. The only possible answer is option C. Option A doesn’t work because plugging in positive values would give negative numbers within the square root which isn’t defined in the real numbers.
