2. 2x+3y>12
5x-3y<15

1.Given : Inequalities  and

To find : Solve the system of inequalities by graphing ?

Solution :

Let the equation 1 -

Equation 2 -

Plot these equation in the graphing tool,

Equation 1  is shown by red dotted line.

Equation 2  is shown by blue dotted line.

The intersection point of the equations is the solution of the system i.e. (0,-1).

Refer the attached figure below.

The solution of inequalities is at (0,-1).

2. Y=5-2x/3

Step-by-step explanation:

answer: it is d

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
