Answer:
Yes (3,9) is a solution.
Step-by-step explanation:
Substitute 9 for y and 3 for x then do the equation and you should get 9=9 for both.
Answer:
<h3>4.1</h3>
Step-by-step explanation:
The quotient id the output of the value when 29 is divided by 118.29
On dividing;
118.6/29 = 4 + {26/29}
4 + {26/29} = 4 + 0.08966
4 + 0.8966 = 4.08966
Hence the best estimate will be the estimate of the value to the nearest one decimal place and that is 4.1.
Answer:
6 ± i and 6 ± i
Step-by-step explanation:
Let x be the first number.
Let y be the second number.
x + y = 12
x × y = 37
Solve for x in the first equation.
x = 12 - y
Put x as 12-y in the second equation and solve for y.
(12- y)y = 37
12y - y² = 37
- y² + 12y - 37 = 0
y = 6 ± i
Put y as 6 ± i in the first equation and solve for x.
x + 6 ± i = 12
x = 12 - 6 ± i
x = 6 ± i
