Answer:
(2, 5)
Step-by-step explanation:
The x coordinate is the number inside the parentheses, but with the opposite sign, 2
The y coordinate is the number at the end
Answer:
Step-by-step explanation:
x = 4
=> y = 3
x = 8
=> y = -2
x = 12
=> y = -5

Answer:
see below
Step-by-step explanation:
For your convenience, the odd numbers are shaded in the attached.
You can use a bit of number logic to determine that the most-significant digit of the 2-digit multiplier must be 2 or 4. Anything larger will not give a 3-digit product. Then the odd digit in the 3-digit multiplicand must be 1 or 3.
Any carry from the product of the least-significant digits must be even in order for the overall product to have an even 10s digit. That is, the two least-significant digits must be 4 and 6 or 8 and 8.

I found the answer by trial and error. The above narrows down the number of possibilities.
Simplifying
8(x + 3) + -2x
Reorder the terms:
8(3 + x) + -2x
(3 * 8 + x * 8) + -2x
(24 + 8x) + -2x
Combine like terms: 8x + -2x = 6x
24 + 6x
30,100= 2,150x
Total x=number per minute
divide 2,150 0n both sides
30,100= 2,150x
____
2,150
Cross it out. Your only left with x.
Then divide 30,100 by 2,150 = 14
x= 14 minutes it will take to completely descend
Your welcome.
