What point the equation

Zinaida [17]

Answer:

Step-by-step explanation:

Put the coordinates of the points and check the equality.

2x + 3y = 8

A. (1, 4) → x = 1, y = 4

2(1) + 3(4) = 2 + 12 = 14 ≠ 8

B. (2, 2) → x = 2, y = 2

2(2) + 3(2) = 4 + 6 = 10 ≠ 8

C. (-1, 3) → x = -1, y = 3

2(-1) + 3(3) = -2 + 9 = 7 ≠ 8

D. (-2, 4) → x = -2, y = 4

2(-2) + 3(4) = -4 + 12 = 8 CORRECT

Please help quick!!

Hi !

$∫ \frac{t}{t + 1}dt$

We need to prove that it is equal to

$∫ \frac{u - 1}{u}du$

As per given options, Substitute u by t+1 

$= > ∫ \frac{u - 1}{t + 1} du$

Then given t = u-1

$= > ∫ \frac{t}{t + 1} du$

Then substitue the third given value also

$= > ∫ \frac{t}{t + 1} dt$

Therefore, it's proved

~Hope it helps
