The correct option is A, which is {(5/7, 12/7)}.
<h2>Given to us,</h2>
equation 1, 5x + 2y = 7,
equation 2, y = x+1
To solve the question, as given in equation 2 the value of y which is equal to x+1, Substitute the value of y in equation 1,

<h3>substituting,</h3>

Now, we have the value of x, substitute the value in equation 2, to get y,

Taking LCM,

Hence, the correct option is A, which is {(5/7, 12/7)}.

Answer:
f(x) = 4.35 +3.95·sin(πx/12)
Step-by-step explanation:
For problems of this sort, a sine function is used that is of the form ...
f(x) = A + Bsin(2πx/P)
where A is the average or middle value of the oscillation, B is the one-sided amplitude, P is the period in the same units as x.
It is rare that a tide function has a period (P) of 24 hours, but we'll use that value since the problem statement requires it. The value of A is the middle value of the oscillation, 4.35 ft in this problem. The value of B is the amplitude, given as 8.3 ft -4.35 ft = 3.95 ft. Putting these values into the form gives ...
f(x) = 4.35 + 3.95·sin(2πx/24)
The argument of the sine function can be simplified to πx/12, as in the Answer, above.
If you divide 8 by three and you'd get 26 but the 6 keep reapeting
“a” would equal 7!! hope this helps :)
