Answer:

An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.

Strike441 [17]

Answer:

discount = 9

new price = 36

Step-by-step explanation:

The new price is the original price minus the discount

Answer:

$y = -x+8$

Step-by-step explanation:

The side that is parallel to BC is EF

Find the slope of EF:

$m = \frac{2-4}{6-4} =\frac{-2}{-2} =-1$

Easiest way is just put the formula in point-slope form and simplify.

Let's use point F, which is (6,2)

$y -2=-(x-6)$

Simplify:

$y-2=-x+6$

Add 2 on both sides:

$y = -x+8$

Hope this helped

Juliette [100K]

If you were asked to express the weight in ounces of a ladybug in scientific notation, would the exponent of 10 be positive or negative? Justify your response. The exponent of 10 would be positive because the weight is measured and is attributed to a living organism hence, there’s no living organism measured in a negative value. Unless it was used otherwise.
