Which linear inequality is represented by the graph?

Art [367]

Answer: The graph is represented by the inequality y>3x+2

Step-by-step explanation:

Linear inequality is like linear equation just we have inequality signs (<,>,≤,≥) instead of equal sign(=).

In the given question we have the linear inequality represented by graph

We can see the line in the graph passing through the point (-3,-7)

Let's check which option satisfy the point

1) y<3x+2 for this the line should be y=3x+2

⇒ -7=3(-3)+2

⇒-7= -9+2⇒-7=-7,which is true.

2) y>3x+2 which similar as first.

3) y<x+2 for this the line should be y=x+2

⇒ -7= -3+2

⇒-7=-1 which is not true.

4) y > x + 2 is similar to third.

Option 3) and 4) cannot be the required linear inequality.

Now from 1) and 2) , 2) should be the required linear inequality as the graph is shaded above the line and that must be for y (>) greater than inequality. [ for y (<) less than inequality the graph must be shaded below the line]

Therefore, 2) y > 3x + 2 is the required linear inequality which is represented by the graph.

Matthew has recorded the amount he's saved every three months. Months Savings 3 $1,800 6 $3,600 9 $5,400 Christopher saves $550

sammy [17]

The correct answer is:

Matthew's rate is higher by $50 per month.

Explanation:

We know that Christopher's rate is $550 per month.

To find Matthew's rate, we will treat the data we have as ordered pairs:
(3, 1800)
(6, 3600)
(9, 5400)

We find the slope of the line between these points. The formula for slope is:

$m=\frac{y_2-y_1}{x_2-x_1}$

Using the first two points, we have:
$m=\frac{3600-1800}{6-3}=\frac{1800}{3}=600$

To verify Matthew saves the same amount each month, we will find the slope between the second two points and make sure they're the same:

$m=\frac{5400-3600}{9-6}=\frac{1800}{3}=600$

Matthew's rate is $600 per month.
This is higher than Christopher's by 600-550=$50 per month.

Simplify the expression 3a+4+b+2a+5+b

ss7ja [257]

3a + 4 + b + 2a + 5 + b

Group like terms:

3a+2a+b+b+ 4+ 5

5a + 2b + 4 + 5

= 5a+2b+ 9

hope this helps!
