How do you solve the equation 132 equals 11z?
It is the same as: 11z = 132
Divide both sides by 11: z = 12
What word problems can be written with x plus 13 equals 25?
Identify the number which, when increased by 13, equals 25.
Thirteen more than a number is 25.
How do you integrate of e -2x for x0?
The integral of e-2x is -1/2*e-2x + c but I am not sure what "for x0" in the question means.
Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.
Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.

What does b mean in y equals m times x plus b?
Y = mX + b This is the general form of the equation of a straight line graphed on X-Y coordinates. 'm' is the slope of the line 'b' is the Y-intercept, that is, the number on the Y-axis where the line crosses it
What is 8x cubed plus 4x squared plus 6x plus 3?
8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
Solve and check the system Y-2x equals 0 x-2y equals 6?
y - 2x = 0 so y = 2x; x - 2(2x) = 6 ie -3x = 6 so x = -2, making y = -4
Check:
1. does -4 - 2 (-2) = 0? yes ,-4 + 4 = 0
2. does -2 - 2 (-4) = 6? yes, -2 + 8 = 6
a = 8, b = 14.
How do you find graph cordinates in this problem 5x-9y equals 43 3x plus 8Y equals 68?
5x - 9y = 43 (A)3x + 8y = 68 (B)
(A)*3: 15x - 27y = 129
(B)*5: 15x + 40y = 340
Subtracting the first from the second gives
67y = 211 => y = 211/67 = 3.15 approx
Substituting the [rational] value of y in (B)
5x - 9*211/67 = 43 => 5x = 43 + 1899/67 = 4780/67
therefore x = 956/67 = 14.27 approx.
What is answer for x divided by 3 equal 27?

How do you sole X when logx-3 plus logx-2 equals log2x plus 24?
We can't see the parentheses, and there are at least two ways to read this.
Here are solutions for the most likely two:
--------------------------------------------------------
log(x) - 3 + log(x) - 2 = log(2x) + 24
Add 5 to each side:
log(x) + log(x) = log(2x) + 29
Subtract log(2x) from each side:
log(x) + log(x) - log(2x) = 29
Combine the logs on the left side, and massage:
log( x2/2x ) = log( x/2 ) = 29
Take the antilog of each side:
x/2 = 1029
Multiply each side by 2:
x = 2 x 1029
------------------------------------------------
log(x - 3) + log(x - 2) = log(2x + 24)
Combine logs on the left side:
log[ (x-3) (x-2) ] = log(2x + 24)
Take antilog of each side:
(x-3) (x-2) = 2x + 24
Expand the left side:
x2 - 5x +6 = 2x + 24
Subtract (2x+24) from each side:
x2 - 7x - 18 = 0
Factor:
(x - 9) (x + 2) = 0
Whence:
x = 9
x = -2
We have to discard the solution [ x = -2 ] because one term in the equation
is log(x-2).
If 'x' were -2 then we'd have log(-4) but negative numbers don't have logs.
