Answer:
1. 5 2. 31 3. 55
Step-by-step explanation:
1. 2(4)-3=8-3=5
2. 4(7)+3=28+3=31
3. 3(4)+8(7)-13=12+56-13=56-1=55
Answer:

1 in 5 times you play, you'll win. every time you play 5 times, you'll win one, so if you play 10 times (double) you'll win double (twice)
Given:
The graph of a translation. X'Y' is a translation of XY.
To find:
The rule of the translation.
Solution:
Let the rule of the translation be
...(i)
So, we need to find the value of a and b.
From the given graph, it is clear that X(-4,-9) and X'(-1,0).
Using (i), the image of X(-4,-9) is
We have, X'(-1,0). So,

On comparing both sides, we get



And,


So, the missing values in the rule of the translation are 3 and 9 respectively.
Therefore, the rule of translation is
.
Answer: If we throw 4 cubes, there are 1296 different outcomes are possible.
Step-by-step explanation:
Given : A cube has faces numbered 1 to 6.
So the number of outcomes for throwing one die = 6
If we throw 4 cubes , then
According to the Fundamental counting principle,
The total number of different outcomes are possible = 
Therefore , The total number of different outcomes are possible 
Hence, there are 1296 different outcomes are possible.
