This question, by asking which graph is decreasing for all values of x, basically asks you to pic the graph that is ALWAYS decreasing. remember that you must read graphs from left to right, the same way you read a book.
the second two graphs you attached can't possibly be your answer. the third graph is constant, until it sharply INCREASES. because the x values start increasing at some point, it's wrong--you only want decreasing x variables. the same thing goes for the fourth graph--it's increasing, then levels out, then continues increasing.
for the first two graphs, follow the shape of the graph from left to right. graph 1 is inclining, going up, INCREASING. graph 2 is falling, and therefore decreasing. graph 2 is the graph that decreases for all values of x.
17/30 of her fish are either testras or guppies :)
(1/6) + (2/5)
(5/30) + (12/30) = 17/30
Answer:
x=4
Step-by-step explanation:
2x+3=11
2x+3-3=11-3
2x=8
x=4
2x+3=11
2(4)+3=11
8+3=11
11=11
<span>As its name implies, an adjustable rate mortgage (ARM) is one in which the rate changes (adjusts) on a specified schedule after an initial “fixed” period. An ARM is considered riskier than a fixed rate mortgage because your payment may change significantly. plz mark me as brainliest im really trying to earn a new rank :(</span>
