Find the slope of the line graphed below.

Mathematics
1 answer:
RUDIKE [14]3 years ago
3 0

Given:

The graph of a line.

To find:

The slope of the graphed line.

Solution:

From the given graph it is clear that the line passes through the points (-2,2) and (2,5). So, the slope of the line is:

m=\dfrac{y_2-y_1}{x_2-x_1}

m=\dfrac{5-2}{2-(-2)}

m=\dfrac{3}{2+2}

m=\dfrac{3}{4}

Therefore, the slope of the given graphed line is m=\dfrac{3}{4}.

The sum of two rational numbers is -2. If one of the numbers is -14/5, find the other.
Marat540 [252]

Answer:

\frac{4}{5}

Step-by-step explanation:

\frac{ - 14}{5}  + x =  - 2 \\ x =  - 2 +  \frac{14}{5 }  \\ x =  \frac{ - 10 + 14}{5}  \\ \: x =  \frac{4}{5}  \\ therefore \: the \: other \: number \: is \:  \frac{4}{5}

Two airplanes leave an airport at the same time, flying in the same direction. One plane is flying at twice the speed of the oth
olasank [31]

Answer:

One plane has a speed of 450 km/h and the other has a speed of 900 km/h.

Step-by-step explanation:

I am going to say that:

The speed of the first plane is x.

The speed of the second plane is y.

One plane is flying at twice the speed of the other.

I will say that y = 2x. We could also say that x = 2y.

Two airplanes leave an airport at the same time, flying in the same direction

They fly in the same direction, so their relative speed(difference) at the end of each hour is y - x = 2x - x = x.

If after 4 hours they are 1800 km apart, find the speed of each plane

After 1 hour, they will be x km apart. After 4, 1800. So

1 hour - x km apart

4 hours - 1800 km apart

4x = 1800

x = 1800/4

x = 450

2x = 2*450 = 900

One plane has a speed of 450 km/h and the other has a speed of 900 km/h.

Vicky ran 5⁄14 of a mile and walked 1⁄7 of a mile. how much further did vicky run than walk?
raketka [301]
To solve, we need to subtract from these two fractions. In order to do this, we will change one of them to have the same denominator as the other.

We have 5/14 and 1/7
Let us change 1/7

Multiply 2/2 (a form of 1 so it does not change the value of the fraction)

2/2 • 1/7 = 2/14

Now subtract from 5/14
5/14 - 2/14 = 3/14

ANSWER: Vicky ran 3/14 of a mile more
