Which is the correct label of the parallel lines?
liq [111]

Answer:

a ∥ b

Step-by-step explanation:

The symbol "∥" means parallel lines.

Taking a look at the figure above, we have 2 parallel lines, labelled a and b.

A and B are two points on line "a", forming segment AB. However, segment AB is part of line "a".

Same applies to line "b", which has 2 points forming segment CD.

Therefore, the correct label if the parallel lines is a ∥ b

-5 (-1 + 6)need help ​
suter [353]

Answer:

-25

Step-by-step explanation: When you multiply to negatives together you get a positive thus being shown in the problem -5 times -1 =5 then you multiply 6 times -5 and whenever you multiply a positive number by a negative you'll always get a negative number so 6 times -5 =-30 then you add 5 and -30 and you get -25. I hope this is right :D

slamgirl [31]

Answer:D

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 8.5%/100 = 0.085 per year

putting time into years for simplicity

6 months ÷ 12 months/year = 0.5 years

then, solving our equation

I = 10000 × 0.085 × 0.5 = 425

I = $ 425.00

on a principal of $ 10,000.00

at a rate of 8.5% per year

for 0.5 years (6 months) is $ 425.00
