True. The midsegment of a triangle is halfway up the triangle, and since the top half and the full triangle are similar triangles, its dimensions are proportional.
This means half the height will give half the base (midsegment). So the midsegment is always half the length of the side it's parallel to.
Answer:
change in the total cost for each book printed = $15
cost to get started (before books are bought) = $1200
Step-by-step explanation:
IF the eqn is y = 15x +1200
where y represent the total cost of publishing a book (in dollars) and
x represent the number of copies of the book printed
then cost to get started (before books are bought) can be found by substitute x=0 into the eqn
y = 1200 + 15*0 = $1200
change in the total cost for each book printed will be the difference in total cost at x=0 and x=1
when x=0, y=1200
when x=1, y=1200+15*1=1215
so the change in total cost=$15
we have
--------> equation A
----> equation B
Substitute equation A in equation B
therefore
<u>the answer is the option B</u>
Answer:
k+1/2 =4
subtract 1/2 from both sides
= k = 3.5 or 3 1/2
Answer: inequality
Step-by-step explanation:
An <u>inequality</u> is a sentence that uses the symbols >, <, ≥, ≤, or ≠ to show a relationship. Here are some different inequalities for an example:
6 < 11
7 > 2
12.5 ≠ 13.5
