Answer:
Yes, a ratio can be simplified.
Step-by-step explanation:
An example of this is 5:10, where it can be simplified down to 1:2.
Answer:
3x
Step-by-step explanation:
Value of x is -1
The correct first step to solving the inequality is distributing the -4 into the para thesis
It looks like it goes through (0,-3) and (1,2), so the gradient is (change in y)/(change in x) ->
(-3-2)/(0-1) = 5
So y=5x+b
Then as we know it passes the y axis at (0,-3) so b= -3
So we have y=5x-3
Tan^2x + 1 + tanx - 3 = 0 tan^2x + tanx - 2 = 0 (tanx + 2)(tanx - 1) = 0 tanx = -2 or tanx = 1 x = 2.034 radians or x = 5.176 radians or x = pi/4 radians or x = 5pi/4 radians
