Answer:

$\boxed{\bf \cfrac{\boxed{c}}{\boxed{a }+ b}}$

Step-by-step explanation:

Given:

$\tt (x_1,y_1) : A (0,0)$

$\tt (x_2,y_2) : C (a+b, c)$

$\boxed{\tt Slope= \cfrac{y_2,y_1}{x_2,x_1}}$

$\tt \cfrac{c - 0}{a + b - 0}$

Add zero (Anything plus zero gives itself).

$\tt \cfrac{c}{a + b + 0}$

$\tt \cfrac{c}{a + b}$

A company that offers tubing trips down a river rents tubes for a person to use for $20 and “cooler” tubes to carry food and wat

aivan3 [116]

The group rent 11 river rent tubes and 4 cooler tubes.

Step-by-step explanation:

Rent for river rent tube = $20

Rent for cooler tubes = $12.50

Total spent = $270

Total tubes rented = 15

Let,

x be the number of river rent tube.

y be the number of cooler tubes.

According to given statement;

x+y=15 Eqn 1

20x+12.50y=270 Eqn 2

Multiplying Eqn 1 by 20

$20(x+y=15)\\20x+20y=300\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(20x+20y)-(20x+12.50y)=300-270\\20x+20y-20x-12.50y=30\\7.50y=30$

Dividing both sides by 7.5

$\frac{7.5y}{7.5}=\frac{30}{7.5}\\y=4$

Putting y=4 in Eqn 1

$x+4=15\\x=15-4\\x=11$

The group rent 11 river rent tubes and 4 cooler tubes.

Divide x^3+2 by x+1 long division ppleeease! :)

anzhelika [568]

Long division: (x³ + 2) ÷ (x + 1)

 x² – x + 1 
x³ + 0x² + 0x + 2 | x + 1
– x³ – x² ⋮ ⋮
– x² + 0x ⋮
+ x² + x ⋮
+ x + 2
 – x – 1
+ 1

 Quotient: Q(x) = x² – x – 1;

Remainder: R(x) = + 1.

I hope this helps. =)
