Find the slope of the line passing through the points (-2,5) and (3/2, 2).
sveticcg [70]

Answer:

The answer is

<h2>-  \frac{6}{7}</h2>

Step-by-step explanation:

The slope of the line passing through two points can be found by using the formula

<h3>m =   \frac{y2 - y1}{x2 - x1}</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question

The points are (-2,5) and (3/2, 2)

The slope is

<h3>m =  \frac{2 - 5}{ \frac{3}{2}  + 2}    \\  =   -  \frac{3}{ \frac{7}{2} }  \\  = -  3 \div  \frac{7}{2}  \\  =  - 3 \times  \frac{2}{7}</h3>

We have the final answer as

<h3>-  \frac{6}{7}</h3>

Hope this helps you

A student is selling small and large frozen pizzas for a school fund-raiser.
dexar [7]

System of equations:

We'll need one equation for the amount of pizzas, and another for the total cost of the pizzas. In this case, x will represent small pizzas, and y will represent large pizzas.

3x + 4y = 100

x + y = 30

Solving the system of equations:

First, we need to solve for one variable in one equation.

x + y = 30

x = 30 - y

Then, we'll take our equation that is solved for x and plug it into the other equation from above.

3(30 - y) + 4y = 100

Next, we solve for y.

90 - 3y + 4y = 100

90 + y = 100

y = 10

Finally, we take our value for y and plug it back in to the very first equation and solve for x.

x = 30 - 10

x = 20

Answer:

The student has sold 10 large pizzas and 20 small pizzas.

Hope this helps!! :)
