Answer:

$1)13x - 15 = 12x + 16 \\ 13x - 12x = 15 + 16 \\ x = 31$

$2)9x - 19 = 2x - 5 \\ 9x - 2x = 19 - 5 \\ 7x = 14 \\ \frac{7x}{7} = \frac{14}{7} \\ x = 2$

$3)16x - 35 = 7x - 8 \\ 16x - 7x = 35 - 8 \\ 9x = 27 \\ \frac{9x}{9} = \frac{27}{9} \\ x = 3$

$4)6x - 5 = 13 - 3x \\ 6x + 3x = 5 + 13 \\ 9x = 18 \\ \frac{9x}{9} = \frac{18}{9} \\ x = 2$

$5)4x - 9 = 6 - x \\ 4x + x = 9 + 6 \\ 5x = 15 \\ \frac{5x}{5} = \frac{15}{5} \\ x = 3$

$6)5x - 2 = 10 - x \\ 5x + x = 2 + 10 \\ 6x = 12 \\ \frac{6x}{6} = \frac{12}{6} \\ x = 2$

hope this helps

Write equation of these in point slope form.

Rufina [12.5K]

1. m=2/5 point= (3,9)

y - 9 = 2/5(x - 3)

2. m= -5 point= (-6,8)

y - 8 = -5(x + 6)

3. m= 0.5 point= (-3,-3)

y + 3 = 0.5(x + 3)

4. m= -4 point= (1,2)

y - 2 = -4(x -1)

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
