Answer: C

Step-by-step explanation:

If a line is perpen to another line, then the other line has the opposite reciprocal of the slope.

PLEASE HELP FAST I NEED 100% Contractor 3 gives Mrs. Solar the following fee table showing her charges for the contract work. a)

NARA [144]

rate of change is the slope

slope = (y2-y1)/(x2-x1)

m= (180-120)/(3-2)

m = 60/1

m = 60

b. point slope form

y-y1 = m(x-x1)

y-120 = 60 (x-2)

c see attached graph. x>=0 since it is hours

d the y intercept is

y -120 = 60x-120

add 120 to each side

y = 60x

2(x-1) ≥ 10 or 3-4x > 15<br> Solve the compound inequality, and show work!

Veseljchak [2.6K]

Answer:

$x\geq 6\text{ or } x$

Step-by-step explanation:

We have the compound inequality:

$2(x-1)\geq10\text{ or } 3-4x>15$

Let's solve each of them individually first:

We have:

$2(x-1)\geq10$

Divide both sides by 2:

$x-1\geq5$

Add 1 to both sides:

$x\geq6$

We have:

$3-4x>15$

Subtract from both sides:

$-4x>12$

Divide both sides by -4:

$x$

Hence, our solution set is:

$x\geq 6\text{ or } x$

The volume of a cylinder is 500pi cm. The radius of the base of the cylinder is 5 cm. What is the height of the cylinder?

patriot [66]

Answer:

20cm

Step-by-step explanation:

Volume of cylinder = (pi) r^2 x height.

Rearrange:

500pi/5^2 pi = height

500pi/25pi = 20

Height = 20cm

Hope this helped!
