1 YEAR = 365 days
365 days * 24 hours = 8760 hours
8760 hours * 60 minutes = 525,600 minutes
=> 1 year has 525,600 minutes
now take 2,720,000 miles / 525,600 minutes = 5.17 miles per minutes
Let us assume the unknown number to be = x
Then, based on the information's already given in the question the equation can be written as
7x - 12 = 16
7x = 16 + 12
7x = 28
x = 28/7
= 4
So from the above deduction we can conclude that the unknown number in the question is 4. I hope the procedure is simple enough for you to understand.You can always use this method in future for solving similar problems.
1. The function of this graph is f(x) = 0.5x + -2
Plug (-2) into the x variables so it looks like:
f(-2) = 0.5 (-2) + -2
Then solve.
Answer: f(-2) = -3
**I'm not as sure about this one, so I might be wrong
2.
For #8, the y-intercept is 4 (you're right) and it represents the initial distance before she started hiking (D)
I tried to figure #9 out, but I couldn't find the answer. I came across a website that might help though: https://sciencing.com/determine-practical-domain-range-10052000.html
**I can't see #s 6 or 7
Answer: x=-2
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
Hope this helps you out.
