Simplifying
5y + -1 = y + 9
Reorder the terms:
-1 + 5y = y + 9
Reorder the terms:
-1 + 5y = 9 + y
Solving
-1 + 5y = 9 + y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-1y' to each side of the equation.
-1 + 5y + -1y = 9 + y + -1y
Combine like terms: 5y + -1y = 4y
-1 + 4y = 9 + y + -1y
Combine like terms: y + -1y = 0
-1 + 4y = 9 + 0
-1 + 4y = 9
Add '1' to each side of the equation.
-1 + 1 + 4y = 9 + 1
Combine like terms: -1 + 1 = 0
0 + 4y = 9 + 1
4y = 9 + 1
Combine like terms: 9 + 1 = 10
4y = 10
Divide each side by '4'.
y = 2.5
Simplifying
y = 2.5
Give the six trigonometric function of 120?
sin(-120)=sqrt(3)/2
cos(-120)=-1/2
tan(-120)=-sqrt(3)
csc(-120)=2/sqrt(3)
sec(-120)=-2
cot(-120)=-1/sqrt(3)
What is the derivative of f of x equals 1?
f(x)=1
f'(x)=0 because the derivative of a constant is ALWAYS 0.
Is 3 a solution of 4x plus 2 minus 3c equals negative1 plus 6?
Since your equation has two variables in it ( 'x' and 'c' ), a "solution" is a number for each of them
that makes the equation true.
Sure, if you want 'x' to be 3, I can figure out what 'c' has to be.
And if you want 'c' to be 3, then I can figure out what 'x' has to be.
But the "solution" is a pair of numbers that tells you what they BOTH have to be.
And in order to figure that out for two variables, you need two equations.
M divided by X is M/X, except when X is zero, in which case it is invalid. Other than that, since insufficient information was given in the question, no other answer can be given.
What is y²-12y plus 36 equals 9?
y^2 - 12y + 36 = 9
subtract 9 from each side
y^2 - 12y + 27 = 0
easy factoring by inspection
(y - 3)(y - 9)
y = 3
y = 9
x+y = 8
-x+2y = 7
Add both equations together:
3y = 15
Divide both sidea by 3 to find the value of y:
y = 5
Substitute the value of y into the original equations to find the value of x:
Therefore: x = 3 and y = 5
How do you solve the equation 6x-3x plus 8 equals x-9 plus 17?
6x-3x+8=x-9+17 -write out the equation
3x+8=x-9+17 - bring whole numbers to the right by subtracting it from
-8 -8 both sides if it is positive. If it is negative, add it to both
______________ sides
- Bring variables to left by repeating the same steps as the
3x=x-9+9 steps taken for the whole numbers.
-x -x - divide your whole number by the coefficient or multiply by 2
_________
2x=-9+9
2x=0
x=0
How do you solve 2x plus 3 equal 9 X equals?
The equation is 2(x) +3= 9. X would equal 3. The equation would now look like this, 2x3+3=9.
Can 20 over 132 be simplified?
20/132
factor out a 4
4*5/4*33
as the factor 4 appears in both numerator and denominator once each it can be eliminated
= 5/33
======
If: 850 = 0.30x
Then: x = 850/0.30 = 2833.333 ... recurring
What number is missing out of the first thrity digits of pi?
There is no 0 in pi until the 32nd digit.
x+x/2 = 700
Multiply all terms by 2 to eradicate the the 2 denominator:
2x+x = 1400
3x = 1400
Divide both sides of the equation by 3 to find the value of x:
x = 466 and 2/3
What is an inverse of a function?
The opposite of another function - if you apply a function and then its inverse, you should get the original number back. For example, the inverse of squaring a positive number is taking the square root.
