Step-by-step explanation:
Answer:
g(f(-4)) = -8
f(g(x)) = 13-10x
Step-by-step explanation:
g(f(-4)):
Plug in the equation f(x) into the variable x of g(x), we have:

Plug in x = -4 and the answer is -8
f(g(x)):
Plug in the equation g(x) into the variable x of f(x), we have:

Answer:
the answer is x = -6 and x =5

Answer:
The correct answer is D. (1,6)
Step-by-step explanation:
When plugged into the equations, it is written 10(1) + 2(6) = 22 and 3(1) - 4(6) = -21. For the first one, 10 x 1 = 10 and 2 x 6 = 12. 10 + 12 = 22. For the second one, 3 x 1 = 3 and 4 x 6 = 24. 3 - 24 = -21. This makes both equations correct, making (1,6) the answer.
Answer: Option A
P(B and V)=10%
Step-by-step explanation:
To solve this poroblema we use the formula of combinations:

Where n is the number of objects that can be chosen and you choose r from them.
There are 5 colors of shirts.
The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:



The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:

Then the probability is:
