Answer:
-22k - 67m
Step-by-step explanation:
You have to use the Distributive property:
8(k + m) - 15 (2k + 5m)
8k + 8m - 30k - 75m
Now simplify:
8k - 30k + 8m - 75m
-22k - 67m
Be careful with positives and negatives!
Hope this help!
Answer:
This is a proportional relationship because for every increase in x there is an increase of 2 in y starting out x=1 y=4

Answer:
y = -4/5x + 2 & y = -2/7x - 4/7
Step-by-step explanation:
(4x) - 5y = -10 (2x) - 7y = 4
Move 4x on the same side as -10 Move 2x on the same side as 4
-5y = 4x -10 -7y = 2x + 4
Divide -5 to both sides Divide -7 by both sides
That should isolate the y for both equations.
4x/-5 = -4/5x....-10/-5 = 2 2x/-7 = -2/7x....4/-7 = -4/7
y = -4/5x + 2 y = -2/7x - 4/7
If that wasn't the answer to your question, I'm sorry.
But if it did, then your welcome.
Answer:
2: 45 3: 45 4: 135 5: 135 6: 45 7: 45
Step-by-step explanation:
they are vertical angles meaning they will mirror each other, subract 135 from 180 and you will get the other angle
