Answer:
reflected across the x axis
Step-by-step explanation:
The solution is x = 6
Step-by-step explanation:
Let us revise some rules of the exponents
- If
, then n = m 
∵ 
∵ 9 = 3 × 3
∴ 9 = 3²
- Substitute 9 by 3² in the equation above
∴ 
- Use the second rule above for the left hand side
∵ 
∴ 
∴ 
- By using the first rule above
∴ 2x + 30 = 7x
- Subtract 2x from both sides
∴ 30 = 5x
- Divide both sides by 5
∴ 6 = x
The solution is x = 6

Answer:
D. y=70x
Step-by-step explanation:
The cheetah was clocked running 70 miles per hour.
i.e. in 1 hour cheetah covered 70 miles
in 2 hours cheetah covered 140 miles
in 3 hours cheetah covered 210 miles
in general, in n hour cheetah covered 70n miles
If y denote the distance covered
and x denotes the time cheetah runs
Then, y=70x
Hence, the equation which shows the relationship between the distance, y, and time, x, the cheetah runs is:
D y=70x

Answer:
The answer is 5.
Step-by-step explanation:
Total number of people noticed by author = 28
Total number of black haired people = 27
So, total number of non black haired people = 1
Also given that 6 people had whole row of seats to themselves.
Let x be the number of non black haired people who had a whole row to themselves.
Since there is only one person with non black hair and has a whole row to himself because it is mentioned that one person had a row to himself which is non black haired.
Looking at above information we can say that x = 1.
Now we can say that the number of black haired people who had a whole row to themselves = 6-x
or 
Hence, the answer is 5.
