How are the real solutions of a quadratic equation related to the graph of the quadratic function?

1 answer:

7 0

The solutions you get when you solve the formula are the corresponding y coordinates to your x value. So say a point on your graph is (2,3). The first number is x and the second is y. (x,y). The number you plug into your function is x,or in this case: 2. The solution to the equation when the x value is plugged in is y, or 3. Therefore, giving you a point on your graph.

Line segment JM has endpoints with coordinates 0 and 25 on a number line. Points K and L are on segment JM. K has a coordinate o

Pepsi [2]

Answer:

D. 216/625

Step-by-step explanation:

The length of the segment JM is 25 units.
The segment JL is between 0 and 12, so is 12 units.
The segment KL is between 5 and 12, so is 7 units.

The probabilities for each point:

P(point on JL) = 12/25
P(point not on KL) = 1 - 7/25 = 18/25

Required probability:

P = 12/25*18/25 = 216/625

Correct choice is D

Brian has 16 yards of chain measured and cut at the. Hardware store. The chain will cost him 47.52$ how much is that per food? _

mojhsa [17]

3 feet= 1 yard

16*3= 48 feet.

47.52/48= 0.99

It will cost Brian $0.99 per foot.

Find the unit rate.

49.50/50= 0.99

No, it wouldn't. It would be the same price

0.99=0.99 It doesn't matter which one Brian chose. 

I hope this helps!
