This is problem #9. I'm not sure how to solve #10, although the solution may be found in a similar way.
Answer: Integer
Step-by-step explanation: The answer would be integer
Answer:
B
Step-by-step explanation:
x + 3y = 7 → (1)
3x + 2y = 0 → (2)
Multiplying (1) by - 3 and adding to (2) will eliminate x
- 3x - 9y = - 21 → (3)
Add (2) and (3) term by term to eliminate x
0 - 7y = - 21
- 7y = - 21 ( divide both sides by - 7 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 3(3) = 7
x + 9 = 7 ( subtract 9 from both sides )
x = - 2
solution is (- 2, 3 ) → B
Answer: its not showing the
Step-by-step explanation:
2•(1/4)^(2-1)= 2•(1/4)= 1/2
2•(1/4)^(3-1)= 2• (1/4)^2 = 2•1/16=1/8
