Answer:

The slope is -50. The slope means that the amount of money in the account is decreasing at a rate of  $50 every week.

Step-by-step explanation:

Given coordinates are (4,2400)\ and\ (12,2000)

We need to find the slope of the graph, and explain what does slope means for this graph.

The formula for computing slope (m) is  

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

Where (x_1.y_1) and (x_2,y_2) are the point on the line.

Let us plug points (4,2400)\ and\ (12,2000) in the equation

m=\frac{2000-2400}{12-4}\\ \\m=\frac{-400}{8}\\\\m=-50

Here, the negative sign of slope (m) represents that the value of the function (budget) is decreasing, with an increase in time (week).

The slope is -50. The slope means that the amount of money in the account is decreasing at a rate of  $50 every week.

Nookie1986 [14]

Answer:

There are 3 adults in the family.

Step-by-step explanation:

The equations 8x + 4y = 32 and 16x + 12y = 72 represent the cost of lunch and dinner for a family in which x is the number of adults and y is the number of children.

We have to find the number of adults or the value of x by solving these equations.

equations are 8x + 4y = 32 -------(1)

16x + 12y = 72 --------(2)

Now we will multiply equation 1 by 3 and subtract it by equation 2.

(16x + 12y) -3(8x + 4y) = 72 - 96

16x + 12y - 24x - 12y = -24

(16x - 24x) + (12y - 12y) = -24

-8x = - 24

8x = 24

x = 3

Therefore, there are 3 adults in the family.
