Answer: 2(0) + 8 does not equal 12, not a solution.
2(2) +8 = 12 yes it is a solution
2(-3) + 8 does not equal 12, not a solution
2(5) + 8 does not equal 12, not a solution.
Step-by-step explanation:
Looks like you need to plug in each y value given and multiplied by 2 and add 8
2(0) + 8 does not equal 12, not a solution.
2(2) +8 = 12 yes it is a solution
2(-3) + 8 does not equal 12, not a solution
2(5) + 8 does not equal 12, not a solution.
r = 255
r = R-2RF/W
R = 1,750
F = 63.2
W = 148
Now, we need to plug the values in to substitute the variables with real numbers.
r = 1750-2(1750 x 63.2)/148
First, solve for the parentheses.
r = 1750-2(110600)/148
Second, multiply by 2.
r = 1750-221200/148
Next, divide by 148.
r = 1750 - 1494.594
Then, we subtract.
r = 255.406
Lastly, we round it to the nearest whole number.
r = 255

x = 24
Step-by-step explanation:
Answer:
The length of the prism is 4.87 inches
The width of the prism is 2.87 inches
The height of the prism is 2.87 inches
Step-by-step explanation:
Let
l -----> the length of the prism in inches
w ----> the width of the prism in inches
h---> the height of the prism in inches
we know that
The volume of the prism is
we have
so
-----> equation A
----> equation B
-----> equation C
substitute equation B and equation C in equation A and solve for l
Solve the cubic equation by graphing
using a graphing tool
The solution is l=4.87 in
see the attached figure
Find the value of w
The approximate dimensions of the prism are
The length of the prism is 4.87 inches
The width of the prism is 2.87 inches
The height of the prism is 2.87 inches
Answer:
This can be solved like this:
4x-3x+9=20
<em>Solving 4x-3x</em>
x+9=20
Transposing +9
x=20-9
And now we have, x=11
