1) -x + 4 = -2x - 6

Add(2x)

x+4=-6

Subtract(4)

x = -10

<u>Check your work</u>

-(-10)+4=-2(-10) - 6

10+4=-2(-10) - 6

14=-2(-10)

14=20 - 6

14=14

Correct :)

2) 4R - 4 = 3R + 10

Add 4

4R=3R+14

Subtract 3R

R = 14

<u>Check your work</u>

4(14)-4=3(14)+10

56-4=3(14)+10

52=3(14)+10

52=42+10

52=52

Correct :)

3) 2Y - 3 = Y - 4

Add 3

2Y = Y - 1

Subtract Y

Y = -1

<u>Check your work</u>

2(-1)-3=-1-4

-2-3=-1-4

-5=-5

Correct :)

<em>Hope it helps <3</em>

The value of a boat if depreciating at at a rate of 9% per year. In 2006 the boat was worth $17,800. Find the worth of the boat
svetlana [45]

Answer:

The worth of boat in 2013 will be $9202.6

Step-by-step explanation:

Rate of depreciation = 9% = 0.09

Cost of Boat in 2006 =$ 17,800

Cost of Boat in 2013 = ?

Years = 2013-2006= 7 years

The formula used is: \mathbf{A=P(1+r)^{t}}

Since the value of boat is depreciating the value of r will be r=-0.09

Here P = 17,800 , r=-0.09 and t = 7 years Finding A

A=P(1+r)^{t}\\A=17,800(1+(-0.09))^7\\A=17,800(0.91)^7\\A=17,800(0.517)\\A=9202.6

So, the worth of boat in 2013 will be $9202.6

For what value of x would the expression below be undefined? 2x − 15 x + 9
Naddik [55]
Hey there!

I'm assuming your expression is actually \frac{2x - 15}{x + 9}. If it's not, let me know and I'll be happy to help you out further. 

If x were equal to –9, your expression would be undefined. If you solve it with this value plugged in for x, you will get the following: 

\frac{2x - 15}{x + 9}

\frac{2(-9) - 15}{(-9) + 9}

\frac{-18 - 15}{0}

\frac{-33}{0}

error

You can't divide anything by zero. This expression would be undefined if x were –9 since it makes the denominator zero. Therefore, x ≠ –9. 

Hope this helped you out! :-)
