For function to be linear , degree(highest power must be 1) like y=2x but here....y=constant which has a degree 0 hence not linear
Answer:
4r + 4(r + 3) = 68
r = 7 miles per hour
r + 3 = 10 miles per hour
Step-by-step explanation:
distance = rate * time
a)
4r + 4(r + 3) = 68
Distribute
4r + 4r + 12 = 68
8r + 12 = 68
8r = 56
r = 7 miles per hour
r + 3 = 10 miles per hour
Answer:
10
Step-by-step explanation:
Answer:
2000
Step-by-step explanation:
1600 is 100% - 20% = 80% of the original price.

So, the marked price is 1600 * 5/4 = 2000
Answer:
Step-by-step explanation:
<u>Given function</u>
<u>Its inverse is</u>
- x = (f^-1(x) - 3)/5
- 5x = f^-1(x) - 3
- f^-1(x) = 5x + 3
The second option is correct
