15x - 10 = -9x + 2 <br> please help me !!!!!

DerKrebs [107]

15x - 10 = -9x + 2

15x +9x -10 = -9x + 9x + 2

15 x + 9x - 10 + 10 = 2 + 10

15 x + 9 x = 2 + 10

24x = 12

24x/24 = 12/24

x = 1/2

hope this helps

The average discharge at the mouth of the Amazon River is 4,900,000 cubic feet per second. How much water is discharged from the

Misha Larkins [42]

Answer: Average discharge at the mouth of the Amazon River in 1 hour = $1.764\times 10^{10}$ cubic feet

Average discharge at the mouth of the Amazon River in 1 year= $3.66912\times10^{13}$ cubic feet[/tex]

Step-by-step explanation:

Given : The average discharge at the mouth of the Amazon River =4,900,000 cubic feet per second.

i.e. The average discharge at the mouth of the Amazon River in 1 second= 4,900,000 cubic feet

Since 1 hour = 3600 seconds

Then , the average discharge at the mouth of the Amazon River in 1 hour =

$4900000\times3600=17640000000$ cubic feet

Since , there are 2080 hours in a typical year.

Then, the average discharge at the mouth of the Amazon River in 1 year=

$2080\times17640000000\\\\=36,691,200,000,000=3.66912\times10^{13}$ cubic feet

Please help! Given the function problem

dedylja [7]

Answer:

Step-by-step explanation:

So we have the function:

$f(x)=\frac{9}{5}x+32$

To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:

$x=\frac{9}{5}f^{-1}(x)+32$

Subtract 32 from both sides:

$x-32=\frac{9}{5}f^{-1}(x)$

Multiply both sides by 5/9. The right side will cancel. Thus:

$f^{-1}(x)=\frac{5}{9}(x-32)$

Our answer is B.

And we're done!
