Answer:
17
Step-by-step explanation:
The circle is open if the inequality is greater than (>) or less than (<) and closed if the inequality is greater than or equal to (≥) or less than or equal to (≤)
If the arrow points to the right (—>) towards bigger numbers, x (whatever number is on the line) will be GREATER (> or ≥)
If the arrow o points to the left (<—) towards smaller numbers, x will be LESSER (< or ≤)
1. Starts at -2 with a closed circle and goes in the positive direction —>
So x ≥ -2
2. Starts at 2 with an open circle and goes in the negative direction <—
So x<2
And the rest use the same method.
Answer: 5
Step-by-step explanation:
D = √(x₂ - x₁)² + (y₂ - y₁)²
x₁ =2 y₁ =6 x₂ =7 y₂ =6
D =√(7-2)² +(6-6)²
D=√(5)² +(0)²
D =√25
D=5
Answer:
$2.48
Step-by-step explanation:
He paid $20 and got $12.56 back so you subtract
20-12.56=7.44
So his total was 7.44 and he bought 3 bags so divide to find the individual price
7.44/3=2.48
So $2.48
