Can someone provide a detailed, step by step explanation on proving the following equivalence theorem? Since this is a proof of an equivalence theorem, we are required to prove all statements, in such a way that, proving the next statement, assuming the previous statement. That is in the order (a)==>(b), (b)==>(c), . , (t)==>(u), (u)==>(a) . We cannot assume (b) and then prove (d), (e) etc. We can assume (b) is true and only prove that (c) is true. The order must be preserved. This is proof and hence the proof would only be valid if ALL the statements are proved in the correct.

Hope you will be kind enough to address follow-up questions, just in case.

Thank you very much!

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

u get 2 big as balls

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
