Answer:

Slope and a point that is not an intercept

Step-by-step explanation:

This is because 3/8 becomes your slope, and the 28 represents how much he had left, which makes it a random point on the graph due to the fact that it is not what time Hiro started, nor a meter either, making it not an intercept.

Carlos's restaurant check is for $24.50. If he wants to add a 17% tip, what total amount should he pay?
Licemer1 [7]
First, convert the 17% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 17%) by 100%.So, the conversational term "17%" becomes 17% / 100% = 0.17 in terms of a real mathematical number.
Second, you need to find out what 17% of your $24.50 meal cost is.This is always done by multiplying 0.17 by $24.50

0.17 x $24.50=$4.16.
So, the amount of tip you are going to leave is $4.16.

This makes the total cost of your meal (to write on your charge slip or other payment)

$24.50 + $4.16 = $28.67.

State the value of the discriminant for <br><br>y = <img src="https://tex.z-dn.net/?f=5x%5E2%2B9x-3" id="TexFormula1" title="5x^
Nostrana [21]

Answer:

141, meaning that there will be two real solutions

Step-by-step explanation:

The discriminant of a quadratic is b^2-4ac, which in this case is:

9^2-4(5)(-3)=81+60=141

Since the discriminant is positive and not zero, there will be two real solutions to this equation. This is because when the discriminant is negative, and you take the square root of it, you get a negative number. If you take the square root of 0, you get 0, which means that there will only be one solution to the equation.

Hope this helps!
