What is comparing decimals

1 answer:

7 0

Say if one decimal is a higher number in the Tenths place, then it is larger than a decimal with fewer tenths. If the Tenths are equal compare the hundredths to thousandths and ect. Until one decimal is larger or there are no more places to compare. If each decimal place value is the same then the decimals are equal. Hope that helped! :)

Determine which of the lines, if any, are parallel. Explain.

amid [387]

Answer:

Line A and Line C are parallel

Step-by-step explanation:

Slope Equation: $m=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Step 1: Find the slope of the first line

Line a passes through (-1, -2) and (1, 0).

$m = \frac{(0- (-2))}{(1 - (-1))}$

$m=\frac{2}{2}$

$m=1$

Step 2: Find the slope of the second line

Line b passes through (4, 2) and (2, -2).

$m = \frac{(-2- 2)}{(2 - 4)}$

$m = \frac{-4}{-2}$

$m=2$

Step 3: Find the slope of the third line.

Line c passes through (0, 2) and (-1, 1).

$m=\frac{(1-2)}{(-1 - 0)}$

$m=\frac{-1}{-1}$

$m=1$

Answer: Line A and Line C are parallel
