The equation is not setup properly, possibly it is your teacher's fault.
From external research, I would say the answer is x = -12.
Ircuit contains a 1.5 volt battery and a bulb with a resistance of 3 ohms. Calculate the current. I = V ÷ R = 1.5V ÷ 3Ω = 0.5A. 5. What current flows through a hair dryer plugged into a 120 Volt circuit
Answer:
B) 4
Step-by-step explanation:
We can solve this by observing some pattern.
The powers ending in 4 as unit digit are:
The exponents form the sequence:
2,6,10,14,20,...
We need to check if 62 belongs to this sequence.
This is an arithmetic sequence with a common difference of 4 and a first term of 2.
The explicit formula is
We equate this to 62 and solve for n.
Since n is a natural number, 62 belongs to the sequence.
Hence
will have a unit digit of 4.

The slope of a perpendicular line is the opposite of the given line.
x -> -x
Find a y-intercept that crosses through the point (0, -2).
y = -x - 2 works!
Now change the equation from slope-intercept form to standard form [ Ax + By = C ].
y = -x - 2
y + x = -2
x + y = -2
Best of Luck!
