Answer:
B
Step-by-step explanation:
Cand D: A= bh
A: A = (a+b)/2h
E: A= 6a^2
Answer:
Step-by-step explanation:
To find the inverse of y=4x+12, all you need to is swap x an y and then remake y the subject.
y=4x+12
Swap x and y:
x=4y+12
Solve for y:
Subtracting 12 on both sides:
x-12=4y
Dividing 4 on both sides:
So
9514 1404 393
Answer:
B. -1
Step-by-step explanation:
The relevant points on the graph are (1, 3) and (4, 0). The average rate of change can be found using the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (0 -3)/(4 -1) = -3/3 = -1
The average rate of change from x = 1 to x = 4 is -1.

Answer: Choice A</h3>
The -3 out front of that function means |-3| = 3 is the amplitude, which is the largest of the four functions.
In general, the sine function is
y = A*sin(B(x-C)) + D
where |A| is the amplitude. In the first answer choice, A = -3 so |A| = |-3| = 3.
Cosine has the same format since cosine is just a phase shift of sine.
