How can you tell whether an ordered pair is a solution of a linear inequality?

sweet-ann [11.9K]

Hello from MrBillDoesMath!

Answer:

Suppose the ordered pair is (x.y). Substitute these values in the linear equality to see if it is true,

Example. Consider the point (7, -4). Is it a solution of the linear inequality

3x < 4y - 9? Let's check to find out.

Check:

Is 3 (7) < 4 (-4) - 9 true ?

Is 21 < -16 -9 = -25 ??

NO!

So (7,-4) is NOT a solution of the linear inequality.

Thank you,

MrB

Choose the equation that represents the graph.

sveticcg [70]

Answer:

Answer: Option D

Step-by-step explanation:

Hey there!

From the above question;

The line passes through (-3,0) and (0,3).

Use double point formula;

$( y - y1) = \frac{(y2 - y1)}{(x2 - x1)} (x - x1)$

Keep all values;

$(y - 0) = \frac{(3 - 0)}{(0 - ( - 3))} (x + 3)$

Simplify it;

$y = \frac{3}{3} (x + 3)$

Therefore, y = x+3.

Hope it helps!

The cost of a company picnic varies directly as the number of employees attending the picnic. If a company picnic costs $487.50

Drupady [299]

The company picnic cost $ 1300 for 80 employees

Solution:

Given that cost of a company picnic varies directly as the number of employees attending the picnic

Let "c" be the company picnic cost

Let "n" be the number of employees attending the picnic

Therefore,

$cost \propto \text{ number of employees attending picnic }$

$c \propto n\\\\c = kn$

Where "k" is the constant of proportionality

c = kn ---------- eqn 1

Given that company picnic costs $487.50 for 30 employees

Therefore substitute c = 487.50 and n = 30

$487.50 = k(30)\\\\k = \frac{487.50}{30} = 16.25$

How much does a company picnic cost for 80 employees?

Substitute n = 80 and k = 16.25 in eqn 1

$c = 16.25(80) = 1300$

Thus $ 1300 is the cost for 80 employees
