Solve the inequality: 3z−1≤−7

Select one:

z≥2

z≥−2

z≤−2

z≤2

Step-by-step explanation:

1) Add 1 to both sides.

2) Simplify -7 + 1 to -6.

3) Divide both sides by 3.

4) Simplify 6/3 to 2.

Therefor, the answer is Option C.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
