(18-7x)+1= -9 Hope this helps ^^
Answer:
D. 4 x minus 3 y = 16. 8 x minus 6 y = 34
Step-by-step explanation:
A. 2 x + 8 y = 15. 4 x + 16 y = 30.
Multiply the first equation by 2
4x+16y = 30 This is identical to the second equation so there are infinite solutions
B. 2 x - y = 18. 4 x + 2 y = 38.
Multiply the first equation by 2
4x -2y = 36. Add to the second equation 8x = 74 so there is one solution
C. 4 x + 7 y = 17. 8 x minus 14 y = 36.
Multiply the first equation by 2
8x +14y = 34 Add this to the second equation 16x = 70 There is one solution
D. 4 x minus 3 y = 16. 8 x minus 6 y = 34.
Multiply the first equation by 2
8x - 6y = 32 Subtract this from the second equation 8x - 6y = 34
0 = 2
This is never true so there is no solution
Answer:
I dont have one
Step-by-step explanation: I just need these 50 points srry :((((((((((
Option C:

Solution:
Sample space for two dice

Number of sample space = 36
Pair getting sum of 12 = (6, 6)
Number of pair getting sum of 12 = 1
Pair getting doublet = (1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6)
Number of pair getting doublet = 6
Total number of pair getting sum of 12 or doublet = 1 + 6 = 7
Probability of getting sum of 12 or doublet


Hence,
is the probability of getting a sum of 12 or doublet when rolling a pair of dice.
Answer: OPTION A.
Step-by-step explanation:
You can rewrite it as following:
a. 
This means that you must substitute x=10 into the limit.
There is not x, therefore the result is 10:

b. 
This means that you must substitute x=-1 into the limit. Then:
