Which graph shows the solution to the inequality -3x-7<20
2 answers:
Answer:
Step-by-step explanation:
Solve the inequality for x
To get rid of -7, add 7 on both sides
now we divide both sides by -3. Whenever we divide by any negative number we flip the inequality sign
We use number line
x is greater than -9. So we shade the number line to the right of -9
Use open circle at -9 and shade to the right.

4x + 6 < -6
First, subtract 6 from both sides. / Your problem should look like: 3x < -6 - 6
Second, simplify -6 - 6 to -12. / Your problem should look like: 3x < -12
Third, divide both sides by 4. / Your problem should look like: x <
Fourth, simplify
to 3. / Your problem should look like: x < -3

Answer:
≈ 15.08 units²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × ( r is the radius )
= π × 6² ×
= 36π × = π ×
=
≈ 15.08
