Which linear inequality is represented by the graph?

laiz [17]

<h2>Answer</h2>

$y\leq \frac{1}{2} x+3$

<h2>Explanation </h2>

First we are going to find the equation of the solid line passing trough the points (0, 3) and (2, 4).

Using the slope formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{4-3}{2-0}$

$m=\frac{1}{2}$

Now we can use the point slope formula to complete the line equation:

$y-y_{1}=m(x-x_{1})$

$y-3=\frac{1}{2} (x-0)$

$y-3=\frac{1}{2}x$

$y=\frac{1}{2}x+3$

Since the shaded region is bellow the line $y=\frac{1}{2}x+3$ , the inequality represented in the graph is $y\leq \frac{1}{2} x+3$ .

1) $400 interest is earned on a principal of $2,000 at a simple interest rate of 5%

Kitty [74]

Answer:

4 years

Step-by-step explanation:

I = $ 400

R = 5%

P =$ 2000

I = Prt

400 = 2000 * $\frac{5}{100}$ * t

400 = 20 * 5 * t

400 = 100 t

$\frac{400}{100}=t$

t = 4 years
