Dafna1 [17]2 years ago
6 0

Answer:

1 real solution

Step-by-step explanation:

y=2x^2−8x+8

We can use the discriminant to determine the number of real solutions

b^2 -4ac

a =2  b = -8  c=8

(-8)^2 - 4(2)(8)

64 - 64

0

Since the discriminant is 0 there is 1 real solution

>0 there are 2 real solutions

< 0 two complex solutions

elena-s [515]
16 divided by 1/8 - 1

first, you would make 16 into a fraction, making the new equation 16/1 divided by 1/8 -1. you'd then flip 1/8 to 8/1 making the new equation 16 divided by 8 - 1. 16 divided by 8 is 2, and 2 - 1 = 1.

11B. Long Beach Towing Company charges $40 plus $5 per mile to
gavmur [86]

Answer:

The charges will be the same after 10 miles.

Step-by-step explanation:

Long Beach Towing Company:

Charges $40 plus $5 per mile. So after x miles, the charge will be of:

L(x) = 40 + 5x

Five-Star Towing Company:

Chargers of $70 plus $2 per mile. So after x miles, the charge will be of:

F(x) = 70 + 2x

After how many miles the charges for the two companied will be the same?

This is x for which:

L(x) = F(x)

So

40 + 5x = 70 + 2x

5x - 2x = 70 - 40

3x = 30

x = \frac{30}{3}

x = 10

The charges will be the same after 10 miles.
