Answer:

(C). {3}

Step-by-step explanation:

$\frac{x}{2(x+1)}$ = $\frac{-2x}{4(x+1)}$ + $\frac{2x-3}{x+1}$ ( x ≠ - 1 )

$\frac{x}{2(x+1)}$ - $\frac{2x-3}{x+1}$ + $\frac{x}{2(x+1)}$ = 0

$\frac{2x-3}{x+1}$ - $\frac{x}{(x+1)}$ = 0

$\frac{x-3}{x+1}$ = 0 ⇒ x = 3

PLEASE Help!

klio [65]

Two triangles are congruent if they have: exactly the same three sides and; exactly the same three angles. the information above is not sufficient for telling there are congruent triagles
so the possible answer is 
-none of the triangles

An object, which is at the origin at time t=0, has initial velocity V0= (-14.0i - 7.0j)m/s and constant acceleration a=(6.0i + 3

sesenic [268]

I am pretty sure the first thing we should do is to integrate acceleration into velocity
And we will have: $a(t) = \ \textless \ 6,3\ \textgreater \$ $v(t) = \ \textless \ (6t+C),(3t+C)\ \textgreater \ ; where -- v(0) = \ \textless \ -14,-7\ \textgreater \$
Then calculate v : $
v(t) = \ \textless \ (6t-14),(3t-7)\ \textgreater \$
As you can see, velocity is zero and none of the objects is moving. It happens when t=7/3 which means we can calculate this in the way we did (integrating) :
 $p(t) = \ \textless \ (3t^2-14t+C) , ((3/2)t^2-7t+C) \ \textgreater \ 
$
The product is p(0) = 0 that makes us to reduce vector function to $p(t) = \ \textless \ (3t^2-14t) , ((3/2)t^2-7t) \ \textgreater \ where t = 7/3$ $p(7/3) = \ \textless \ -49/3 , -49/6 \ \textgreater \$

A local movie theater charges $12 for an adult ticket and $10 for a child's ticket. a group of eight people spent a total of $86

oksian1 [2.3K]

3 adults and 5 kids.

You can get this by setting up the following system of equations.

x + y = 8 (number of people)
10x + 12y = 86 (cost)

When a plant does not get enough water, the turgor pressure inside of the cells?

vivado [14]

Vacuoles are storage bins that are kinda like storage bubbles in plants and animal cells and turgor pressure happens when the water inside the plant cell vacuole starts to expand which pushes the cell memebrance or walls so when a plant doesn't get enough of water the plant will wilt which means the plant ends up losing it turgor pressure as well.
