Answer:
7 x - 8 y = 5
x - 8 y = -13
6 x = 18 subtract equations
x = 3
7 (3) - 8 y = 5
8 y = 16 solve for y
y = 2
Solution : (3, 2)
Check:
3 - 8 * 2 = -13 agrees with second equation
Answer:
The first one is true. 3/6 is greater than 5/12
Step-by-step explanation:
I hope this helps :)
The answer is the first one.

Answer: 2
Each time x increases by 2, the outputs are multiplied by 4 (eg: 3 to 12 is times 4, or 12 to 48 is times 4)
Take the square root of 4 to get 2. So each time x increases by 1, y is doubled
x = 0, y = 3
x = 1, y = 6 <<-- y is doubled
x = 2, y = 12 <<-- y is doubled
and so on
Answer:
,
Step-by-step explanation:
For a single solution, you must have a perfect square trinomial.
