parallel:
Step-by-step explanation:
original line:
y = -5x + 5
=> 5x + y = 5
m = -5/1 = -5
perpendicular:
m = 1/5
L: x - 5y = k
(7, -5) -> L
7 - 5 * (-5) = k
=> 7 + 25 = 32 = k
L: x - 5y = 32
parallel:
m = -5
L: 5x + y = k
(7, -5) -> L
35 - 5 = 30 = k
L: 5x + y = 30

Given:
Andrea multiplied 6.75 x 10^6 and 0.2 x 10^6 and got 6.95 x 10^6.
Question asked:
Explain Andrea’s mistake and give the correct answer.
Solution:
The above question is of <u>exponential question</u>:
Here Andrea simply <u>added </u>6.75 to 0.2 and got 6.95 and took 10^6 as common and written down wholly 6.95 x 10^6 which is incorrect.
Here we <u>multiply</u> 6.75 to 0.2 and get 1.35 and secondly to multiply 10^6 with 10^6 we have to understand the rule of exponents:-
<u>As we know:</u>
<u></u>
Hence when we multiplied 6.75 x 10^6 and 0.2 x 10^6 originally we got
