F(x^2) = x^2 - 3
5f(x^2) = 5x^2 - 15 = 2x - 8
Placing all the terms on the left side, we get:
5x^2 - 2x - 7 = 0 which factorises to
(5x - 7)(x + 1) = 0
So, x = 7/5 or x = -1
But x is non-negative, so x = 7/5 = 1 2/5
C is the answer.
Answer:
The answer is B
Step-by-step explanation:
Answer:
y = 2sinx + 2
Step-by-step explanation:
∵ y = Asin(Bx - C) + D
∵ D is the vertically shift
∵ It moves 2 units up
∴ D = 2
∴ y = 2sinx + 2
The rate of change is equal to the slope of a line. Given any 2 points on a line and you can calculate the slope (rate of change) of that line. The formula for rate of change is given by Δy/Δx which equals (y2-y1)/(x2-x1). Therefore, using the points given in the question and simply input them into our formula, we get ((4)-(3))/((-2)-(0)) = -1/2
Sometimes
LCM of 3 and 4 is 12....(3 x 4)
LCM of 10 and 6 is 30.....not (10 x 6) = 60
