Answer:
(-(23/3), -(11/3))
Step-by-step explanation:
x=y-4
2x-5y=3
=====
2x-5y=3
2(y-4)-5y=3 [Substitute (y-4) for x in the 2nd equation]
2y - 8 -5y = 3
-3y = 11
y = -(11/3)
y = -3 2/3
Use this in the 1st equation to find x:
x=y-4
x=-(11/3)-4
x = -(11/3)-(12/3)
x = -(23/3)
x = -7 2/3

Answer:
A. a + b = 180 is the correct option.
7/(b-36)=28/b
28b-1008=7b
21b=1008
b=48
a/72=28/b
a=72x28/48
a=42
if we deffine the first week as w₁ = 55, the recursive relation that tells us the number of tomatoes on week n will be:
wₙ = 55 + (n - 1)*14
<h3>How to find the recursive formula?</h3>
We know that, at the moment, the tomato plants produced 55 tomatoes, so that is our first element.
We also know that the tomato plants give 14 tomatoes each week, so in week 2 the number of tomatoes is:
w₂ = 55 + 14
On week 3:
w₃ = 55 + 14 + 14
And so on, so if we deffine the first week as w₁ = 55, the recursive relation that tells us the number of tomatoes on week n will be:
wₙ = 55 + (n - 1)*14
