How do i add and subtract polynomials?(4v-6v)-(v-5v^3)+(5v^3+4)

1 answer:

7 0

Distribute and add like terms and you are good

alirghty

we can make it easier by simplifying what we can

(4v-6v)=-2v so

(-2v)-1(v-5v³)+(5v³+3)=
-2v-v+5v³+5v³+3=
10v³-3v+3

a car dealer buys a luxury car for $65,200 and sells it for 85,650. What is the percent increase in the price of the cara car de

nika2105 [10]

Answer:

The percent increase in the price of the car is <u>31.36%</u>.

Step-by-step explanation:

Given:

A car dealer buys a luxury car for $65,200 and sells it for $85,650.

Now, to find the percent increase in the price of the car.

Cost price of the luxury car = $65,200.

Sell price of the luxury car = $85,650.

So, the price of the car increased by:

Sell price of the luxury car - Cost price of the luxury car.

$=\$85,650-\$65,200\\\\=\$20,450.$

<em>Thus, the price of car increased by $20,450.</em>

Now,to get the percent increase in the price of the car:

$\frac{20450}{65200} \times 100$

$=0.3136\times 100$

$=31.36\%.$

Therefore, the percent increase in the price of the car is 31.36%.

Given line LM and point R that lies on line LM, identify the following ratios given that point R lies a/b of the way along line

gavmur [86]

Answer:

See explanation

Step-by-step explanation:

If point R lies $\frac{a}{b}$ of the way along line LM, closer to L than M, then

$LR=ax\\ \\LM=bx$

Find all needed ratios:

1. $\dfrac{LR}{LM}=\dfrac{ax}{bx}=\dfrac{a}{b}$

2. By segment addition postulate,

$LR+RM=LM\\ \\RM=bx-ax=(b-a)x,$

$\dfrac{RM}{LM}=\dfrac{(b-a)x}{ax}=\dfrac{b-a}{a}$

3. $RL=LR=ax\\ \\RM=(b-a)x,$

then

$\dfrac{RL}{RM}=\dfrac{ax}{(b-a)x}=\dfrac{a}{b-a}$
