Answer:

The graphs are posted.

Step-by-step explanation:

the method to solve such inequalities is assume the line and then draw the line then search for the inequality

The y < 0.5x-3

First plot the line y=0.5x-3

Now all the values of y which are below the line satisfies the inequality.

similarly for the second question x+y ≥ 5.

Now assume the line x+y=5

All the values of (x , y) above the line satisfies the equation including the points on the line .

Answer:

Step-by-step explanation:

I gotchu fam. The first thing that you would want to do is find the slope. The slope is the change in y divided by the change in x. Based on the points on the line, the change in y is 2 because it goes up two, and the change in x is one because it goes over 1. This would make your slope 2/1, or just 2! Now we have our slope, so we want to find our y-intercept. There are two ways that we can do this. The first way is just eyeballing it, but sometimes that's not always accurate. We're just going to do that because its faster (lol). It looks around -2. With this information, we have our entire equation! y=mx+b. we can plug in our information. y=2x-2. And that's how your answer's A! Hope this helps.

There are 40Student in a class. If the number of boys is 4less than the number of girls.find the number of boys.

svp [43]

Answer:

Step-by-step explanation:

Let number of girls be 'x'.

So, Number of boys = Number of girls - 4

= x - 4

Total number of students in a class = 40

Number of girls + Number of boys = Total number of students in a class

$\longrightarrow$ x + x - 4 = 40

$\longrightarrow$ 2x - 4 = 40

$\longrightarrow$ 2x - 4 + 4 = 40 + 4

$\longrightarrow$ 2x = 44

$\longrightarrow$ $\sf \dfrac{2x}{2} = \dfrac{44}{2}$

$\longrightarrow$ x = 22

$\therefore$ Number of boys = 22 - 4

= 18
