Algebra II question, urgent!!

Mathematics

GalinKa [24]3 years ago

Hey!
So (f-g)(x) just means f(x) - g(x). So f(x) would come first, so it would look like (4^x-1 + 6) - (2x-5).
Distribute the minus sign and it would come out to be 4^x-1 + 6 - 2x + 5
Then combine like terms: 4^x-1 - 2x +11.
Your answer is A!
Hope this helps!

Write the equation that describes the following variation. Don't forget "k"!
rosijanka [135]

Answer:

x=(k√x)/(w^2)(cube√z)

x varies directly with square root of y is:

x = k √y

And inversely with the square of w and cube root of s is:

/(w^2)(cube√z)

Now put those together:

x=(k√x)/(w^2)(cube√z)

The formula is:

x=ky/wz but add the specific info like square, roots, or etc

A pharmacist has an 18% alcohol solution and a 40% alcohol solution. How much of each should he mix together to make 10 liters o
TiliK225 [7]
Lets call x the amount of 18% solution and y the amount of 40% solution, and write as equations the info of the problem:
18x + 40y = 10(20)
x + y = 10
lets multiply the second equation by -18 and add to the first:
 18x + 40y = 200
-18x -<span> 18y = -180
</span>----------------------
0 + 22y = 20
y = 20/22 = 10/11
and substitute in the original equation:
x <span>+ y = 10
</span>x = 10 - y
x = 10 - 10/11
x = 110/11 - 10/11
x = 100/11
so they have to use 100/11 liters of 18% solution and 10/11 liters of 40% solution
