Hey there!
The answer to your question is the third option: 2n + 7 = 5; n = -1
"twice a number increased by 7" would represent 2n + 7, and if it's equal to 5, it would be 2n + 7 = 5. That rules out the last option, and the second option. Now, we have to solve for "n":
2n + 7 = 5 Step 1: Write the equation.
2n = -2 Step 2: Subtract 7 from both sides.
n = -1 Step 3: Divide both sides by 2.
Therefore, "n" is equal to -1, and the third option would be correct.
Hope it helps! Have a great day, and good luck on your assignment!
Answer:
non liner
Step-by-step explanation:
the second differences are the same
This is an example of a Circle Graph, a circle graph is like a Pie chart, and In graph theory, a circle graph is the intersection graph of a set of
chords of a circle. That is, it is an undirected graph whose vertices
can be associated with chords of a circle such that two vertices are
adjacent if and only if the corresponding chords cross each other.
Look at the graph I showed you

Answer:
89.7% is your answer
<u>or 90% if you round it.</u>
City hall to post office = 6 1/2 miles = represented by f
city hall to library site = 1 1/4 miles = represented by d
library site to post office = unknown. = represented by e
City hall to library site PLUS library site to post office IS EQUAL to city hall to post office
d + e = f
1 1/4 + e = 6 1/2
find e.
e = 6 1/2 - 1 1/4
e = 13/2 - 5/4
e = (13*2)/(2*2) - 5/4
e= 26/4 - 5/4
e = (26-5)/4
e = 21/4
e = 5 1/4 distance from library site to post office.
To check:
d + e = f
1 1/4 + e = 6 1/2
1 1/4 + 5 1/4 = 6 1/2
6 2/4 = 6 1/2
6 1/2 = 6 1/2
