F= -1 2/3 or 5/3

In order to find the answer all you have to do is multiply both sides by -4/3.

-3/4f × -4/3 = f

-4/3 × 5/4 = -20/12

-20/12 simplified is -5/3 or -1 2/3

What us the value of the discriminant of the quadratic equation -2^2=-8x+8 and what does its value mean about the number of a re
svlad2 [7]

ANSWER

The discriminant is zero.

The given equation has one real root.

EXPLANATION

The given quadratic equation is:

- 2 {x}^{2}  =  - 8x + 8

We rewrite this in the form;

a {x}^{2}  + bx + c = 0

- 2 {x}^{2}  + 8x  - 8 = 0

This means that,

a=-2, b= 8, c=-8

The discriminant is given by;

D=b² - 4ac

That is:

D =  {8}^{2}  - 4( - 2)( - 8)

D =  64  - 64 = 0

Therefore the discriminant is zero.

This tells us that the quadratic equation has one real root.

In order words, the given quadratic equation has a repeated real root.

A small airplane flies 750 miles with an average speed of 250 miles per hour. 1.75 hours after the plane leaves, a Boeing 747 le
sleet_krkn [62]

Answer:

The average speed of the 747 was of 600 miles per hour.

Step-by-step explanation:

A small airplane flies 750 miles with an average speed of 250 miles per hour.

Velocity is distance divided by time, and here, we find the time of the small airplane. So

v = \frac{d}{t}

250 = \frac{750}{t}

250t = 750

t = \frac{750}{250}

t = 3

1.75 hours after the plane leaves, a Boeing 747 leaves from the same point. Both planes arrive at the same time;

This means that it traveled 750 miles in 3 - 1.75 = 1.25 hours.

What was the average speed of the 747?

v = \frac{d}{t} = \frac{750}{1.25} = 600

The average speed of the 747 was of 600 miles per hour.

1/2 inch= 3 feet what is the length for 7 inches
Mrrafil [7]
If \frac{1}{2} inch is equal to 3 feet, then 1 inch = 6 feet because \frac{1}{2} * 2 = 1 and 3 * 2 = 6.

Thus 1 x 7 = 7, and 6 x 7 = 42.

42 feet.
