Number of students N, y years

N = 700 + 50y   

N = 700 + 50 x 10 = 1200   (C)

Left not painted percentage = 100 - 60 = 40 %

Left = 40/100 x 45 =  18 (H)

A coordinate plane linear graph shows inequalities. A line goes through (0, 1) and (2, minus 1). Another line goes through (0, m
Alborosie

The region in the graph that represents the solution of the system of linear inequalities y ≥ 2x − 3 and y ≤ -x + 1 is given by C region , This can be clearly understood from the graph attached.

<h3>What is Inequality ?</h3>

When two algebraic expressions are equated by an inequality operator then the mathematical statement formed is called inequality

It is given that a line passes through the points  (0, 1) and (2, minus 1)

The equation of the line representing this is given by

y = mx+c

m = -1

y = -x+1

and the other line passing through the points of (0, minus 3) and (2, 1) is

m = 2

y = 2x -3

These are plotted on the graph

From intersection, region to the right of it is A, below is D, to the left is C, and above is B.

These are noted ion the graph

Then the inequalities are plotted y ≥ 2x − 3 and y ≤ -x + 1

The region in the graph that represents the solution of the system of linear inequalities y ≥ 2x − 3 and y ≤ -x + 1 is given by C region , This can be clearly understood from the graph.

How many lines can you draw using 3 non-collinear points A, B and C on a plane?​
patriot [66]

Answer:3 lines could be used

Step-by-step explanation:

You need 2 points to draw a line. The order doesn't really matter. Line AB is the same as line BA. The problem is to select 2 points out of 3 to draw different lines. If we do the same to the others, we get the following pairs of points to draw lines.

AB , AC

BA , BC

CA , CB

which is only 3 lines

Kailey plays video games for x hours a month. Trent plays video games four hours more than Kylie and Megan plays two times more
Mazyrski [523]

Answer:

8 + 2x

Step-by-step explanation:

Given that :

Kyle's game time = x

Trent's game time = 4 hours more than Kylie = 4 + x

Megan's game time = 2 times more than Trent ; this equals ; 2 * (4 + x) = 2(4 + x) = 8 + 2x
