Answer:
d, x=5
Step-by-step explanation:
1) get photo math the app. amazing.
2) remove parenthaeses 6x+24=12x-6
move terms 6x-12x=-6-24
collect the like terms,calculate
-6x=-30
divide both by -6
x=5
Answer:
D. y= 4x + 13
Step-by-step explanation:
the slope would have to be 4 to be parallel
so plug the points in
1=4(-3) + b
1= -12 +b
13 = b
Answer:
A. 1, 287 ways
B. 154,440 ways
Step-by-step explanation:
A. We want to choose 5 objects from a total 13, without considering the order in which they are chosen.
The correct way to do this is by using the combination formula since order is not considered;
Thus we have ; 13 C 5 read as 13 combination 5;
Mathematically, n C r is ; n!/(n-r)!r!
Thus, we have ;
13!/(13-8)!8! = 13!/5!8! = 1,287 ways
B. By considering order, we shall be using the permutation formula;
Mathematically n P r = n!/(n-r)!
Read as n permutation r;
Using the numbers involved, we have ; 13 P 5
= 13!/(13-5)! = 13!/8! = 154,440 ways

Answer:
74%
