How do you factor x squared minus 2x minus 10 minus 5 equals 0?
x2-2x-10-5 = 0
x2-2x-15 = 0
(x+3)(x-5) = 0
x = -3 or x = 5
Converting square feet to square yards?
The conversion of one yard to feet is three feet per yard. Thus, in a single-dimensioned space, you can simply divide whatever distance is given by 3 to get yards. However, adding a second dimension means you have feet x feet and thus, must convert both dimensions to yards, meaning you have to divide by 3 twice or once by 9.
What is the logarithm of log -1?
Assuming you are asking about the natural logarithms (base e):
log (-1) = i x pi
therefore
log (log -1) = log (i x pi) = log i + log pi = (pi/2)i + log pi which is approximately 1.14472989 + 1.57079633 i
What is the slope of 7x plus 3y equals 9?
Solve for y
3y=-7x+9
y=-7/3x+3
the slope is the coefficient of x
in this case, it is -7/3
Negative x to the second power positive five x plus twenty-four?
x to the second power +11x+24 (x+_)(x+_)
Is there a question here?
What does the variable y equals mx plus b?
That is the equation of a line.
y = m*x + b
x is a changing variable to plot on the x-axis.
m is the slope of the line, or how slanted the line is.
b is the y-intercept, or where the line crosses on the y-axis.
What is the graph for x plus y equals 1 Need a step by step explanation?
The line x + y = 1 will be defined by the points that satisfy that equation. The x-axis travels horizontally, the y-axis travels vertically.
Step 1. Draw the axes on graph paper. Each line should be an integer.
Step 2. Plot points that satisfy the equation, like (0,1)(1,0)(2,-1)(1,-2)(3,-2)(-2,3)
Step 3. Draw a line through them with a pencil using a straight edge of some sort.
When one of the numbers is zero, that's where it crosses the other axis. You'll find that the line crosses the x-axis at 1 on the y-axis and crosses the y-axis at 1 on the x-axis.
What is the factor expression of x2-9x plus 4 equals 0?
That equation can not be factored. It can however be solved for x:
x2 - 9x + 4 = 0
x2 - 9x + 81/4 = 81/4 - 4
(x - 9/2)2 = 81/4 - 16/4
(x - 9/2)2 = 65/4
x - 9/2 = ± √65 / 2
x = (9 ± √65) / 2
2x to the 3 power times 5x to the 3 power?
(2 x3) times (5 x3)= 10 x6
Of course, it could also mean (2x)3 (5x)3 =(8x3 )(125x3 )=1000x6
It all depends on weather you mean the quantity 2x to the third or 2 multiplied by x to the third.
What is even and odd wave function?
A basic wave function is a sine or cosine function whose amplitude may have a value other than 1.
The cosine function is an even function because it is symmetrical about the y-axis. That is, f(-x) = f(x) for all x.
The sine function is an odd function because it is antisymmetrical about the y-axis. That is, f(-x) = -f(x) for all x.
How do you subtract a whole number from a mixed number?
You can do this by temporarily ignoring the fraction part of the mixed number as long as you put it back again when finished!
For example,
For 3 1/4 - 2:
Here we can simply do 3 - 2 which is 1, and then add the fraction back again = 1 + 1/4 = 1 1/4
What is the slope of 2x plus 4y equals 8?
Convert the function into the general form y = mx + c, where 'm' is the slope.
2x + 4y = 8 : 4y = -2x + 8 : y = -x/2 + 2 :
The slope is therefore -1/2.
