Graph the inequality y> 2x +3

Graph the inequality y> 2x +3

Solution

Step 1: To graph the inequality, we need to find a few coordinates and form the table.

Step 2: Forming the table.

Let's take x = -1 and find the value of y.

Plug in x = -1 and find the value of y.

y = 2(-1) + 3 = -2 + 3 = 1

When x = -1, the value of y is 1.

So the coordinates are (-1, 1)

Plug in x = 0 and find the value of y.

y = 2(0) + 3 = 3

The coordinates are (0, 3)

Plug in x =1 and find the value of y.

y = 2(1) + 3 = 2 + 3 = 5

The coordinates are (1, 5)

Steo 3: Now let's plot the points and draw the graph.

Since the graph is greater than, we have to draw the dotted lines and shade the region above.

Note: You can find the graph in the attachment.

Thank you :)

n = 100 (or) 10²

Solution:

Given equation is 1.6 ÷ n = 0.016.

Part A:

To simplify the equation and find the value of n.

1.6 ÷ n = 0.016

$$\frac{1.6}{n}=0.016$

Do cross multiplication.

$1.6=0.016n$

Divide by 0.016 on both sides of the equation.

$$\frac{16}{0.016}=n$

To remove decimal point multiply and divide by 1000 on left side.

$$\frac{1.6\times1000}{0.016\times1000}=n$

$$\frac{1600}{16}=n$

$100=n$

Switch the sides.

n = 100

n = 10²

Hence the value of n is 10².

Part B:

$$1.6\div10^2=\frac{1.6}{100}$

= 0.016

Hence the answer is true.
