Y2-y1=6-4=2
x2-x1=2-1=1
2/1=2
The slope is 2
y=2x+b
4=2(1)+b
4=2+b
-2
2=b

y=2x+2

Solve for u -2/9u=10

Nata [24]

Answer:

$u = -45$

Step-by-step explanation:

Step 1: Multiply both sides by -9/2

$-\frac{2}{9}u = 10$

$-\frac{9}{2} *-\frac{2}{9}u = 10 * -\frac{9}{2}$

$u = -\frac{90}{2}$

$u = -45$

A cylinder has a volume 1200 cubic inches and radius 5 inches. What is the height of the cone to the nearest tenth inch

mihalych1998 [28]

Answer: 15.3 in

Step-by-step explanation:

First, the formula for the volume is: $V=\pi r^2h$

If you solve for h,

$h=\frac{V}{\pi r^2}$

$h=\frac{1200in^3}{(3.14)(5in)^2}$

$h=15.3in$

Hello from MrBillDoesMath!

Answer:

Domain restriction: -3 <= x <= 0

Range restriction: -4 <= y <= 0

Discussion

These numbers came directly from the graph. I am assuming the endpoints such as x = -3 are included in the domain.
