What is tan x degrees equals 90?
tan0.15
Evaluate the expression 3x2y when x equals 3 and y equals 5?
(3 * 3)(2 * 5) (9)(10) 90
15x plus 75 and 6xFind the value of x?
set formula:15x +75 = 6xbring x to left side:15x - 6x + 75 = 09x = - 75x = - 75/9
Is x equals 3 a solution of x-7 equals 4?
no.. x equals 11
How would you find x when 0 equals 2sinxcosx-cosx?
2sinxcosx-cosx=0 Factored : cosx(2sinx-1)=0 2 solutions: cosx=0 or sinx=.5 For cosx=0, x=90 or 270 degrees For sinx=.5, x=30 degrees x = {30, 90, 270}
What is the answer to 75 x equals 750?
If 75x = 750, then (1/75)75x = (1/75)750, or x = 750/75 = 10.
What percent of 75 equals 33?
75x = 33 75x/75 = 33/75 = 0.44 x = 0.44 0.44 x 100 = 44%
How do you find the intercepts of F of X equals 6000 - 75x?
It is 6000.
How do you find the x-intercept of f(x) 6000 - 75x?
my bad its f(x) = 6000 - 75x
What is the slope of y equals .75X plus 7?
.75 (it's simply the number being multiplied by x)
How do you graph f of x equals 75x?
y = f(x) = 75x has a slope of 75 (steep) and an x,y intercept of (0,0). Graph it as a very steep, straight line passing through the origin from lower left to upper right.
Y equals .75x plus 3?
y = 0.75x + 3 (-3) -3 = 0.75x (/0.75) -3/0.75 = x x = -4
What is -x3 plus 75x-250 divided by x plus 10?
(-x3 + 75x - 250) / (x + 10) = x2 - 10x - 25
0.25 x 360 equals?
90
Cos square 90-x equals?
Cos(90 - x) = sin(x) so cos2(90 - x) = sin2(x)
How many solutions do the following equations have in common 8y equals -75x - 22 and 75x equals -8y plus 22?
I notice that the ratio of the y-coefficient to the x-coefficient is the same in both equations. I think that's enough to tell me that their graphs are parallel. So they don't intersect, and viewed as a pair of simultaneous equations, they have no solution.
What does 90 x 12 equals?
90 * 12 = 1080
