Hello there, and thank you for posting your question here on brainly.
Something I noticed right away is that 4/8 can be simplified.
4/8 ===> 2/4
So now we have 2/4 - 1/4
Just subtract the numerators only.
2/4 - 1/4 = 1/4
1/4 cannot be simplified, so 1/4 is your final answer.
Hope this helped!! ☺♥
6[13-2(4+1)]
Solve what is in the bracket first.
Parenthesis first.
6[13-8-2]
6(3)

Answer:
The answer is 2
Step-by-step explanation:
Rate of change of function is given by :

For function y = 6,
rate of change =

because the function is independent of x.
For function y = 2·x + 7,
rate of change =

So, the rate of change of 2 is greater than rate of change of function 1 by 2 - 0 = 2.
Answer:
1.49 hrs or 1 hr and 30 minutes approximately
Step-by-step explanation:
if fran go 2.8m up then the river flow at a rate of 0.8m; the since we are taking the speed of fran and river to be constant. the ratio between their speed will always remain constant. that is if 0.8/2.8 = 0.286≈ this will be always constant.
so if he go up 4m then the horizontal length has to be 1.143 because 1.143/4 = 0.286.
now we find the distance between frans initial positon and final position. to find it we use pythagoras theorem.

to find the time divide distance traveled by speed;
4.160/2.8 = 1.49 hrs
The answer to the question is D. It took me so long cuz' my phone died. *sry*
