Answer:
1. Equal. 2. 1500
Step-by-step explanation:
6 x 16 = 96 + 11= 117
3/4 x 2000 = 1500
8, because the two minuses add up and turn into positive and 1/5 adds to 4/5 and turns into a whole 1 and adds 7 equal 8
Answer:
-7/4
Step-by-step explanation:
<span>This must be your answer:
Expanded: 1/5 x 10x + 1/5 x -25 </span>
You can turn 5 into 10/2 and add to x/2
then you need to use simple algebra to left the x alone in the equation so you need to multiply both sides by 2 so you get
2y=10+x
then you need to subtract both sides a 10 so
2y-10=x
now change the x to f'(x) and y to x so:
f'(x)=2x-10
