I’m so bad at this ughhhhhhhhhhhhhhhhhhh

Answer:

a)6

b)v^2-u^2/2a

Step-by-step explanation:

a)Given that,

u=12

a= -6

s=9

We know that,

v^2=u^2+2as

or, v^2=(12)^2+2×(-6)×9

or,v^2=144-108

or,v^2=36

or, v=√36

∴v=6

(Ans)

b)If ,v^2=u^2+2as

then, u^2+2as=v^2

or,2as=v^2-u^2

or, s=v^2-u^2/2a

∴s=v^2-u^2/2a

Answer:

Step-by-step explanation:

for the right side we can just do 14*2 since there are two people per seat and 14 rows

14 *2 is 28

for the left side we just do 14*3 since there are three people per seat and 14 rows

14*3 is 42

Then we have to add the 8 students that can fit in the very back seat

42 + 28 + 8

28 + 8 is 36

42 + 36 = 78

Answer this by 4:20 EST and I will mark brainliest

Alexxandr [17]

Answer:

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (6, a ) and (x₂, y₂ ) = (9, - 4 )

m = $\frac{-4-a}{9-6}$ = $\frac{-4-a}{3}$

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

2x - 3y = 6 ( subtract 2x from both sides )

- 3y = - 2x + 6 ( divide through by - 3 )

y = $\frac{2}{3}$ x - 2 ← in slope- intercept form

with slope m = $\frac{2}{3}$

Parallel lines have equal slopes , then

$\frac{-4-a}{3}$ = $\frac{2}{3}$ , so

- 4 - a = 2 ( add 4 to both sides )

-a = 6 ( multiply both sides by - 1 )

a = - 6 → A
