Combine like terms-- you can combine the k's:
Now you have:
Simply divide both sides by 2.5 to find the value of k:
The answer to 9+10 is 19 because if you add 9 to the number 10, you get 19
Answer: $34.50
Step-by-step explanation
If you multiply .75=3/4 x 10 it will will be 7.50 so 10x 3.45= 34.50 or 7.50 x 3.45= 25.875
25.875/.75 = $34.50
Vary Directly: y = k*x
Vary Inversely: y = k/x
Because x and y vary directly, our equation will look like the first one.
y = k*x
With the inputted values:
-16 = k * 4
Now, to find k, isolate the variable
k = -16/4 = -4
Your final equation will then look like this:
y = -4 * x
Answer:
C.
Step-by-step explanation:
you want a negative x intercept in order for you to get a lower number for your outcome hope this helps polz mark me brainliest
