Answer:
7k
____________________________________________________
Step-by-step explanation:
We are trying to combine like terms with the expression: -k - ( - 8k)
We are pretty much solving it.
Solve:
-k - ( - 8k)
The "- ( -" turns into a plus sign.
So it would look like:
-k - -8k or -k + 8k
Now, you would finish solving
-k + 8k = 7k

when it’s parallel it has the same slope!
Answer: y = 2
Explanation:
When x = 3, y = -15
And x and y are directly proportional.
thus x + k ==> y + k
when x = 3 + 17 ==> y = -15 + 17
=> x = 20 ==> y = 2
Step-by-step explanation:
I don't know if it's correct
A quarter and a dime are equal to 25 cents and 10 cents, respectively. Let x and be the number of quarter and dime coins. The equations that best expressed the condition are,
x + y = 29
0.25x + 0.10y = 5
The values of x and y are equal to x = 14 and y = 15. Thus, the answer is letter A. 15 dimes and 14 quarters.
