set formula:15x +75 = 6xbring x to left side:15x - 6x + 75 = 09x = - 75x = - 75/9
no.. x equals 11
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}
If 75x = 750, then (1/75)75x = (1/75)750, or x = 750/75 = 10.
75x = 33 75x/75 = 33/75 = 0.44 x = 0.44 0.44 x 100 = 44%
It is 6000.
my bad its f(x) = 6000 - 75x
.75 (it's simply the number being multiplied by x)
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 = 0.75x + 3 (-3) -3 = 0.75x (/0.75) -3/0.75 = x x = -4
(-x3 + 75x - 250) / (x + 10) = x2 - 10x - 25
90
90 x 90 = 8,100
Cos(90 - x) = sin(x) so cos2(90 - x) = sin2(x)
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.
