Please help with this.........

lyudmila [28]

Answer:

Step-by-step explanation:

Use the formula of a midpoint:

$\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)$

We have the points P(-2a, 0) and Q(0, 2b). Substitute:

$x=\dfrac{-2a+0}{2}=\dfrac{-2a}{2}=-a\\\\y=\dfrac{0+2b}{2}=\dfrac{2b}{2}=b$

A family of 3 children and 2 adults visited a health club. The club charges $y an hour for each child and $x an hour for each ad

vovikov84 [41]

Solution:

A family of 3 children and 2 adults visited a health club. The club charges $y an hour for each child and $x an hour for each adult.

First we make inequality according to question.

In a family number of children 3

Charge for 1 child = $y per hour

Charge for 3 children = 3y

Charge for 1 Adult = $x per hour

Charge for 2 adults = 2x

If the family does not want to s[end more than $30 an hour at health club.

$\therefore 2x+3y\leq 30$

Where, x and y should be greater than 0.

$\therefore x\geq 0,y\geq 0$

Now we make the graph of this inequality.

First we take equality of equation and then find x and y table.

2x+3y=30

x y

0 10

6 6

15 0

Here we have inequality. So, we have to take a test point (0,0)

$2(0)+3(0)\leq 30\Rightarrow 0\leq 30$

This statement is true. So, Graph will shade towards the test point (0,0)

Please see the attachment for graph.
