Step-by-step explanation:
line 1 and 2 : parallel
as line 2 is actually
6x + 2y = 8
2y = -6x + 8
y = -3x + 4
so, they have the same slope (factor of x).
line 1 and 3 : neither
the slopes -3 and 3 are not parallel not perpendicular (90°).
line 2 and 3 : neither
as line 2 is parallel to line 1, it has the same relationship to line 3 as line 1.
For this all you need is to balance the equation out with the variables (a) on one side and the number on the other. Also remember that what you do to one side you do to another. So here we have 4=3a-14. You should add the 14 to both sides, on one side to cancel out the 14 and add the 14 on the other side to balance it out. Now you have 18=3a. Divide by 3 on both sides to isolate the variable a and you have your answer. A=6
Answer:
$21.44 or answer D
Step-by-step explanation:
68.99-57=11.99
37.80 x 25/100=9.45
9.45+11.99=21.44
hope this helps you
Answer:
No.
Step-by-step explanation:
Because 4/7=8/14 and 1/2=7/14. 4/7>1/2.
I guess a lot of formatting is missing on your question, so these are the correct steps: using the inverse Pythagorean theorem, we know that the length of the missing side is the square root of the difference of the squares of the hypotenuse and the other leg.
Let x be the length you're looking for, we have

So, it looks like Mike's missing the last step: what he found is the square of the missing leg's length, not its actual length.
