10w-8+6-4w is equal to 6w-2
2(3w-1) = 6w-2
6w-2
(11w-1)-(5w+3)=11w-1-5w-3=6w-2
3w+7+3w-9 = 6w-2
Hope this helps
First lets invert the divisor and chane to a multuplication:-
x + 5 2x^2 - 7x - 4
----------------- * --------------------
2x^2 + 3x + 1 3x^2 + 18x + 15
Now we can factor the 3 trinomials:-
x + 5 (2x + 1)(x - 4)
-------------- * ------------------
(2x + 1)(x + 1) 3(x + 5)(x + 1)
Now we simplify because (2x + 1) and (x + 5) are common to top and bottom:-
1 * x - 4
= ------------- ------------
x + 1 3( x + 1)
= x - 4
--------------
3(x + 1^2
Answer:
2
Step-by-step explanation:
Point c is at (1, 2)
point d is at (2, 4)
rate of change formula
(f(d) - f(c))/2 - 1
f(2) = 4
f(1) = 2
4-2/1 = 2
1. the answer is C
2. the answer is D
