It would be a horizontal line (dotted line) at the y intercept 3. Make a line 3 units up, and it is dotted. Shade below the dotted line, to show the "less than" part. Hope this helps
Answer:
x < 5
Step-by-step explanation:
-7x + 14 > -3x - 6
Collect like terms
-7x + 3x > -6 -14
-4x > -20
Divide both sides by -4
-4x/-4 < -20/-4
Note : dividing both sides of an inequality by negative or minus the inequality sign changes.
Therefore
x < 5

12.6 (simplified to the tenths)
12.57(simplified to the hundredths)
Step-by-step explanation:
The diameter of a circle is always double of the radius
π is always ≈ 3.14
π * 2^2 = π * 4 ≈ 12.566
Answer:
Notebooks: $2.75 each; pens: $1.10 each
Step-by-step explanation:
Let n and p represent the unit cost of notebooks and the unit cost of pens.
Then 3n + 2p = $10.45, and 4n + 6p = $17.60.
Let's use elimination by addition/subtraction to find n and p.
Multiplying the first equation by -3, we get -9n - 6p = -$31.35
and then combine this with the second: 4n + 6p = $17.60
-----------------------------
Then, -5n = -$13.75
Dividing both sides by 55, we get n = $13.75 / 5, so we now know that n = $2.75. Each notebook costs $2.75.
Subbing $2.75 for n in the first equation, we get:
3($2.75) + 2p = $10.45, or
$8.25 + 2p = $10.45
Solving for p, we get p = $2.20 / 2 = $1.10.
Each pen costs $1.10.
