by 4. You do this because you want to find out what x equals. If you divide by 16, you find out what 1/4X equals, and that isn't much good to you. x=4 is the answer.
What is 20x plus 80y equals 0 in y equals mx plus b?
20x + 80y = 0
Subtract 20x from each side of the equation:
80y = -20x
Divide each side by 80:
y = -1/4 x
m = -1/4
b = 0
Which line lies completely between y equals 4x-5 and y equals 4x plus 1?
y = 4x -2.5
----------------
The slope has to be the same as the two original equations, in this case 4. This way the lines are parallel. And the y-intercept has to lie between the two original equations (0,1) & (0,-5) on the y-axis.
Some of these points include:
(0,0) y=4x
(0,-1) y=4x-1
(0,-2) y=4x-2
(0,-3) y=4x-3
(0,-4) y=4x-4
...and so on for any point in between, including (0, -2.5) as the previous poster listed.
What is an equation composed of?
An equation is composed of mathematical statements, which can be arranged to result in a series of equations/inequalities which can be solved for each unknown.
What does x equal if 3 equals 2x plus 5?
3 = 2x + 5
Subtract 5 from each side:
-2 = 2x
Divide each side by 2:
-1 = x
What is the answer to x plus 2 equals 7?
X is a variable. So you subtract 7 minus 2 to find the variable answer.So your answer is 5
How do you factor the trinomial 3z2 plus 45z plus 42?
3z2 + 45z + 42 = 3(z2 + 15z + 14)
= 3(z + 1)(z + 14).
What are the x intercepts of the parabola x2 plus 4x minus 12?
x=2,-6
x^2+4x-12
(x^2-2x)(+6x-12)
x(x-2)+6(x-2)
(x-2)(x+6)=0
How do you graph the linear equation X-Y equals -2?
If: x-y = -2 then the x intercept is -2 and the y intercept is 2
So the points are: (-2, 0) and (0, 2)
What are the symbols used in a set?
A set is a collection of number, letters or things denoted as {things}. for ex. {2,5,6} meaning that x is either 2, 5 or 6.
A = {1,4,5} U {1,2, 3} means A = {1,4,5,2,3} while
B = {1,2,3} ∩ {5, 2, 3} means B = { 2, 3}

Which of the following is equal to the rationa experssion when x equals -4 or 16?
None of the folloing - following even!
How many degrees is 0.875 turn?
That would be 7/8 (seven-eighths) of 360 degrees, which would be 315 degrees. Hope this helps!
What would the answer be if you did elimination for -x 2y4 and 3x-3y-3?
Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question. Please edit your question to include words for symbols and resubmit.
There are no equations in the question, simply a couple of expressions.
How many cubic centimeters are in .00317 cubic meters?
0.00317 cubic meters = 1000000 x 0.00317 cubic centimeters = 3170 cubic centimeters
What is 70.5metersdivided by 60meters equals X divided by 80 centimeters?
70.5 m/60 m = X/80 cm
meters in majority, so
80 cm (1 meter/100 cm) = 0.8 m
restate
70.5 m/60 m = X/0.8 m
easy multiplication, multiply through by 1/0.8 m
70.5 m/48 m = X
1.46875 meters = X

How do you find the volume of the solid between x-y equals 1 and y equals x2-4x plus 3?
Both of those equations represent two-dimensional graphs, so they're not the boundaries
of a solid.
They do, however, enclose an area between them, in the interval between x=1 and x=4.
Evaluating the area takes a little bit of calculus. It's "beyond the scope" of a usual WikiAnswer,
I don't think you want to see that explained in detail, and I don't feel like it right now anyway.
