Answer:
4x + 4
Step-by-step explanation:
(4, 5) and (8, 6) are points on the line.
Using delta method:
4 to 8 = +4
5 to 6 = +1
Slope = 4
The line intercepts the y-axis at (0, 4)
Y-int = 4
Answer : 12.8
Step-by-step explanation: if u round the 7 it is going to be eight because it is bigger than four
Answer:
A is f ", B is f, C is f '.
Step-by-step explanation:
Your answer is correct. B is the original function f. It has a local maximum at x=0, and local minimums at approximately x=-3/2 and x=3/2.
C is the first derivative. It crosses the x-axis at each place where B is a min or max. C itself has a local maximum at approximately x=-3/4 and a local minimum at approximately x=3/4.
Finally, A is the second derivative. It crosses the x-axis at each place where C is a min or max.
The area of a circle is pi times radius^2
So if you use 3.14 x 16, it gives you approximately 50.264
-8x+3y=28
4x-y=-12
<u><em>Step-by-step explanation:</em></u>
Let's find x and y from matrices and then check for this systems.
Simplify, so we got
7-9
28-24
------
So x=-2
y=4
So we need to put those values and check system.
