I believe the answer might be:
x = 28/19
Steps:
Expand
3(5 - x)/2 - 4(3 + 2x)/5
-3x + 15 - 8x + 12
------------ -----------
2 5
Find the LCD for the equation above:
(15-3x) * 5 - (12+8x) * 2
------------- --------------
10 10
Now we combine them since the denominators are equal:
5(-3+15) - 2(8x+12)
--------------------------
10
We expand above:
-31x+51
-----------
10
8
Suppose f(x) = ----------
sqrt(x)
8
What if we let x = 16 (just an example)? We'd get f(16) = ------------- = 2.
sqrt(16)
What if we let x = g(x) = 2x+4?
We'd get the following:
8
f(g(x)) = -------------- = y
sqrt(2x+4)
So...the correct answer is the fourth one.
Answer:
A and E
Step-by-step explanation:
-3(x - y) = -3x + 3y = 3y - 3x
A. E
(x + y = 125)3
5x - 3y = 41
3x - 3y = 375
8x = 416, x = 52
52 + y = 125, y = 73
Solution: the numbers are 52 and 73
Answer:
f(x) = -5x + 4
Domain refers to the values of x that would result to a defined value of y. Since the given f(x) is a linear function, then all the values of x would give a corresponding value of y. So, the domain of f(x)=-5x+4 are all real numbers.
Or, plot the given equation to check.
The graph of f(x)=-5x+4 is shown below.
Since the graph is a straight line and can be extended continuously on both ends, this indicates that every values of x, there is a corresponding value of y.
Hence, the domain of the given function are all real numbers.Step-by-step explanation:
