I’m afraid that it is already written in standard form.
There’s nothing you can do any further then that.
Answer:
C. 3
Step-by-step explanation:
2x+6
Divide 2 on both sides
x=3
Answer:
Step-by-step explanation:
x = -4 and x=1
The solutions to the equation x^2 +3x -4 = 0 will be given by the points at which the graph intercepts the x-axis.
By looking at the graph, we can clearly see that the graph intercepts the x-axis at x=-4 and x=1.
One of the roots is located between -4 and -3, and the other one between 0 and 1.
Answer:
(0,-3)
Step-by-step explanation:
The y digit changes when flipping over the x-axis
Double angle formula for cos(2x) is
cos(2x)=cos^2(x)-sin^2(x)
Substitute x=4theta, then
cos(8theta)=cos^2(4theta)-sin^2(4theta)
=>
cos^2(4theta)-sin^2(4theta) = cos(8theta)
