Find the slope of the line that passes through the points (2,4) and (-4,2)

Mathematics
1 answer:
Nat2105 [25]2 years ago
8 0

Answer:

The slope is 1/3.

Step-by-step explanation:

The formula for slope is \frac{y_{2} -y_{1}}{x_{2}-x_{1}  } where y_{1} and x_{1} are the y- and x-coordinates of the first point, and y_{2} and x_{2} are the y- and x-coordinates of the second point, respectively.

Inputting our values into our formula, we get  \frac{2-4}{(-4)-2}. Solving for the numerator first, we get \frac{-2}{(-4)-2}. Solving for the denominator, we get  \frac{-2}{-6}. This simplifies to 1/3.

Lucy is a dress maker. She sews 4/7 of a dress in 3/4 hour. Lucy sees at a constant rate. At this rate, how many dresses does lu
IgorLugansk [536]

Answer:

Lucy sews \frac{16}{21} dresses in 1 hour.

Step-by-step explanation:

Given:

Lucy sews \frac{4}{7} of a dress in \frac{3}{4} hour.

She sews at constant rate.

We need to find the number of dresses she makes in 1 hour.

In \frac{3}{4} hour = \frac{4}{7} dress

So in 1 hour = Number of dresses in 1 hour

By using Unitary method we get;

Number of dresses in 1 hour= \frac{\frac{4}{7}}{\frac{3}{4}} = \frac{4}{7}\times \frac{4}{3}= \frac{16}{21}

Hence Lucy sews \frac{16}{21} dresses in 1 hour.

Two trains leave Stations 396 miles apart at the same time and travel towards each other. One train travels at 95 mph while othe
PolarNik [594]

It will take 2.2 hours for the trains to meet.

Step-by-step explanation:

Given,

Distance between two trains = 396 miles

Speed of one train = 95 mph

Speed of other train = 85 mph

Combined speed of trains = 95+85 = 180 mph

Distance = Speed * Time

Time = \frac{Distance}{Speed}

Time = \frac{396}{180}

Time = 2.2 hours

It will take 2.2 hours for the trains to meet.
