if f(x)=3-2x and g(x)= 1-x+5, what is the value of (f/g) (8)?
Answer: -169
Step-by-step explanation:
There are two ways to answer this question, and one is a lot easier than the other. The first is to divide f(x) by g(x) and then substitute 8 for x, which could take a very long time and would be a huge pain.
On the other hand, you can substitute 8 into the equation f(x), and get
f(8) = 3- 2(8) = 3-16 = -13
Then substitute 8 into g(x) and get
g(8) = 1 /(8 +5) = 1/(13)
Then you simply divide the two to get -13/(1/13). Here, you can multiply the numerator and the denominator of the larger fraction by 13, so you would end up with -169/1, or, the answer to your problem: -169.
what numbers have a sum of 20 and the difference is 4
Answer:
16 and 2
Step-by-step explanation:
I'm not sure honestly if this is correct, but I hope this helps.
Answer:
The numbers are 12 and 8
Step-by-step explanation:
let the numbers be x and y :
[tex]x + y = 20 - - - (a) \\ x - y = 4 - - - (b)[/tex]
add (a) and (b):
[tex]2x + 0y = 24 \\ 2x = 24 \\ x = 12[/tex]
find y:
[tex]x + y = 20 \\ 12 + y = 20 \\ y = 20 - 12 \\ y = 8[/tex]

Step-by-step explanation:
Answer:
The GCF is going to be 9
Step-by-step explanation:
When finding the GCF, you want to do prime factorization of each number.
18's prime factorization is, 2 × 3 × 3, which equals 18
36's prime factorization is 2 × 2 × 3 × 3, which equals 36
45's prime factorization is 5 × 3 × 3, which equals 45
Now all you have to do is find the factors common in each one, which is 2 three's. You then multiply 3 × 3 = 9. That is your answer

Measuring the speed of sound in the ocean is an important part of marine research. One application is the study of climate change. The speed of sound depends on the temperature, salinity, and depth below the surface. For a fixed temperature of 25 degrees Celsius and salinity of 35 parts per thousand, the speed of sound is a function of the depth. At the surface, the speed of sound is 1534 meters per second. For each increase in depth by 1 kilometer, the speed of sound increases by 17 meters per second.
What increase in the speed of sound is caused by a 4-kilometer increase in depth?
Step-by-step explanation:
speed of sound in x depth = 1534 + 17x
4 × 17 = 68 is the increase of sound speed caused by 4 km increase in depth

Consider the given line segment. If AC is 39cm long, answer the following questions:
A
B
9x+7
-3x+20
AB -
BC =
Is point B the midpoint? (yes or no)
The point which is equidistant from the endpoints of a line segment, hence, marking the middle point of the line is called the midpoint. Therefore, Point B is not the midpoint
AB + BC = AC
9x + 7 + (-3x + 20) = 39
9x + 7 - 3x + 20 = 39
6x + 27 = 39
6x = 39 - 27
6x = 12
x = 12 / 6
x = 2
9x + 7 = - 3x + 20
9(2) + 7 = - 3(2) + 20
25 = 15
Hence,
Since, AB ≠ BC, then B is not the midpoint
