Answer:

Step-by-step explanation:
<u>Given polynomial </u><u>function </u>:-

<u>To </u><u>find</u> :-

<u>Solution:-</u>

Here, the value of x is 7(given).
So, <u>Substitute the value of x on the RHS and </u><u>on </u><u>LHS </u>:-

Simplify the RHS:-
<u>Multiply 10 and 7 :-</u>


<u>Add 70 and 45 :-</u>

We're done!
Hence, the value of f(7) would be,


I hope this helps!
Let me know if you have any questions.
Answer:
y=2x/3+3-----------------P
Putting X = -2 in eq P
y=2(-2)/3+3
= -4/3+3=5/3
x,y= -2, 5/3
If k=20 minutes
Each day Sasha will exercise 2 times more. 2 times more than k is 2k.
So first week Sasha will exercise k+2k+3k+4k+5k+6k=20+40+60+80+100+120=440 minutes
The formula to show how long Sasha will exercise each day next week is:
440 + 20*x
where 440 is initial exercise time, and x is number of day in next week.
