The square root of 16 is 4.
The formula for slope is: m = (y2 - y1) / (x2 - x1)
For this problem: x1 = -3 y1 = 4 x2 = 2 y2 = -1
m = (y2 - y1) / (x2 - x1) ---> m = (-1 - 4) / (2 - -3) = -5 / 5 = -1
Problem find the slope of: 2x + 3y = 12
To find the slope of a line, you can place the equation into y-form, the slope will be the coefficient of x.
2x + 3y = 12
3y = -2x + 12
y = (-2/3)x + 4
The slope is -2/3.
Problem: find the x- and y-intercepts of 8x - 2y = 24.
To find the x-intercept, substitute 0 for y: 8x - 2(0) = 24
8x - 0 = 24
8x = 24
x = 3 ---> (3, 0)
To find the y-intercept, substitute 0 for x: 8(0) - 2y = 24
0 - 2y = 24
-2y = 24
y = -12 ---> (0, -12)
3u - 7 = -37
3u = -30 (Add 7 to both sides.)
u = -10 (Divide both sides by 3.)
-v + 5 + 6v = 1 + 5v + 3
5 + 5v = 5v + 4 Now, subtract 5v from both sides:
5 = 4
Since this is impossible, the original expression really isn't an equation; therefore, there is no solution.
One standard deviation from the mean (both larger than and smaller than) holds approximatedly 68% of the population.
That means that 32% of the population is farther than one standard deviaiton from the mean, half of that (16%) is larger than one standard deviation above the mean and the other half (the other 16%) is smaller than one standard deviation below the mean.
Just use the slash button.
You just either type in you problem or press the buttons. Does that help?

aX + 7 =4X
aX - 4X = -7
X(a-4) =-7
X= -7/(a-4) or 7/(4-a)
Is this an assignment or something you cooked in your head?
last three digits of 1011*2012*3013*4014*5015*6016= 742,222,980,525,152,885,760
Huh. Cool.
im doing math BAD
Well, technically it would be a multiple of itself, wouldn't it?
Multiply the exponents together and cube the numerals to get
27x^6y^9
8.9*1.5 = 13.35 <---This is Kareem's pay
7.1*2 = 14.2 <---This is Cheryl's pay.
As we can see, 14.2>13.35, so Cheryl gets paid more for 1 hour of overtime.
Right now, you cannot simplify the problem further because there is nothing to simplify. The equation is x2.
if 3t - 7 = 5t then 6t = what?
3t - 7 = 5t subtract 3t from both sides
-7 = 2t divide both sides by 2
-7/2 = t = -7/2
So...6t = 6(-7/2) = -42 / 2 = -21
3t-7=5t
Subtract 3t from both sides
2t=-7
Divide by 2
t=-3.5
So now that we know what t is equal to, we can substitute it into the second equation.
6t
6(-3.5)
-21
So, 6t=-21
