Answer:
b = 7 1/4
Step-by-step explanation:
7 = -1/4 + b
Add 1/4 to both sides
7 1/4 = b
b = 7 1/4
Step-by-step explanation:
The solution can be found by identifying the point of intersection of the 2 graphed lines.
As we can see, they intersect each other at the point (2, -3). This is our solution for the equations.
Answer:
C: 9076.3 cm^3
Step-by-step explanation:
Use the formula for the volume of a cylinder.
V=πr^2 times h
h=25
Here, I'm assuming 21.5 cm is the diameter, so divide 21.5 cm by 2 to get 10.75 as r.
V=(10.75^2)π times 25
115.5625π times 25
This is about 2889π
This simplifies best to choice C, which is about 9076.3 cm^3
However, if I was wrong about 21.5 cm being the diameter, my answer is wrong. If 21.5 cm is r, choice D is the correct answer. If 21.5 cm is the diameter, C is the answer.
<span>15x + 3y = 10.
you have to solve for y.
isolate the variable.
15x + 3y = 10
start by subtracting 15x on both sides.
3y = -15x +10
then divide both sides by 3
y = -15/3x + 10/3
simplify.
y = -5x + 10/3
10/3 can be written as 3.33
or 3 and 1/3</span><span>
