Please help me with this

Masja [62]

Answer:

c = a - 16

Step-by-step explanation:

Given

a = b + 12 ( subtract 12 from both sides )

a - 12 = b

Substitute b = a - 12 into b = c + 4

a - 12 = c + 4 ( add 12 to both sides )

a = c + 16 ( subtract 16 from both sides )

c = a - 16

Nathan has just bought a new car. He models the value, V, in dollars, of the car after t years as V(t) = 21,000(0.861)t. Based o

UkoKoshka [18]

Answer:

13.9%

Step-by-step explanation:

The value of car is modeled as:

$V(t)=21,000(0.861)t$

Here we can see that, each year Nathan has considered 0.861 of the previous year value or we can say that Nathan has considered 86.1% of the previous year value. So,

$100-86.1=13.9$

We subtract the percentage value considered from 100 to find out the percentage decrease in the value of the car.

The value of new car is decreasing by 13.9% each year.

Please Help!!<br> f(x) = square root of x plus 7 ; g(x) = 8x -11 <br> Find f(g(x))

Sonja [21]

I'm not sure if you mean ( $\sqrt{x + 7}$ ) or ( $\sqrt{x} + 7$ ) I solved it both ways .

$f(x) = \sqrt{x + 7} \\ \\ f( \: g(x) \: ) = \sqrt{(8x - 11)+ 7} \\ = \sqrt{8x - 11 + 7} \\ = \sqrt{8x - 4} \\ = 2 \sqrt{2x - 1}$

____o_____o______

$f(x) = \sqrt{x} + 7 \\ \\ f( \: g(x) \: ) = \sqrt{(8x - 11)} + 7 \\ = \sqrt{8x - 11} + 7\\$

I hope I helped you^_^
