Answer:
the answer is 68.397
Step-by-step explanation:
becasue you round 3 down on the 4 digit after the decimal
(a) The y-intercept is when x=0, so the answer is (0,3).
(b) Perpendicular lines have gradients that multiply to -1, so the gradient of B is 1/4.
So, the equation is y = ¼x + 3.
Answer:
g(f(3)) = 0
Step-by-step explanation:
f(x) = 2x - 9
f(3) = 2(3) - 9
f(3) = -3
g(-3) = 9 - (-3)^2
g(-3) = 9 - 9
g(-3) = 0

0.6n = 84
Solve
By:
Move all terms containing n to the left, all other terms to the right.
Divide each side by '0.6'.
n = 140
