Answer:
12
Step-by-step explanation:
let x = number of 3 wheel stollers
let y = number of 4 wheel strollers
x + y = 28
y = 28 - x
3x + 4y = 100
3x + 4(28 - x) = 100
3x + 112 - 4x = 100
-x = -12
x = 12
And there you go, your answer is 12.
The Exponent tells you how to move the decimal to the right. So
-2.56 x 10^3 says move the decimal 3 places to the right:
-2560 is the original number ~ Which Im guessing is the standard form...
The composite function of the paintings Jenny completes in a year is
<h3>What is a composite function?</h3>
A composite function is a function made of other functions, where the output of one function is the input to the other function.
An example of the composite functions 2x+3 and together make the composite function
We have
Here, P(w) represents the number of paintings Jenny completes in some w weeks. and
J(y) represents the number of weeks per year.
As J(y) is the number of weeks spent per year in painting, we can calculate the paintings completed in a year by substituting
w as J(y) in the equation we have
Then the equation becomes:
Hence this is the composite function that would represent the number of paintings Jenny completes in a year.

Answer:
C. c = (xv - x) / (v - 1).
Step-by-step explanation:
v = (x + c) / (x - c)
(x - c) * v = x + c
vx - vc = x + c
-vc - c = x - vx
vc + c = -x + vx
c(v + 1) = -x + vx
c = (-x + vx) / (v + 1)
c = (-x + xv) / (v + 1)
c = (xv - x) / (v + 1)
So, the answer should be C. c = (xv - x) / (v + 1).
Hope this helps!
