Third, expand your problem. / Your problem should look like: -3x + 15 - 8y - 16 - 18 + 12b
Fourth, simplify. / Your problem should look like: -3x - 8y + 12b - 19

−3(x−5)−8(y+2)−3(6−4b)

Distribute:

=(−3)(x)+(−3)(−5)+(−8)(y)+(−8)(2)+(−3)(6)+(−3)(−4b)

=−3x+15+−8y+−16+−18+12b

Combine Like Terms:

=−3x+15+−8y+−16+−18+12b

=(12b)+(−3x)+(−8y)+(15+−16+−18)

=12b+−3x+−8y+−19

An investment of $8500 increases in value by 4.5% every year. How long until the investment
riadik2000 [5.3K]

Answer:

16 years

Step-by-step explanation:

Given data

Principal= $8500

Rate= 4.5%

Final amount=  $17,323

The expression to find time in compound interest is given as

t= ln(A/P)/r

substitute

t= ln(17323/8500)/0.045

t= ln(2.038)/0.045

t=0.711/0.045

t= 15.8 years

Hence the total time is about 16 years

Rufina [12.5K]

Answer:

I say the answer is ball 4

Step-by-step explanation:

The reason why I chose ball 4 was because ball 4 has less mass and the mass for ball 4 is only 300 and I'm pretty sure if you rolled ball 4 it would've went the farthest because it's mass is lesser than the others.

Required

The domain of the graph

To do this, we simply write out the range of value of the x-coordinate.

From the attached graph, the x values are:

x = [0,40] i.e. from 0 to 40 (both inclusive)

So, the domain is:

\{x: 0 \le x \le 40 \}
