Answer:
E = (-2, -1.5), see attached for a plot
Step-by-step explanation:
We want point E such that ...
EC/DC = 3/4 . . . . . . . . the ratio of segment lengths is 3/4
(E -C)/(D -C) = 3/4 . . . . the ratio of coordinate differences is 3/4
4(E -C) = 3(D -C) . . . . . cross multiply
4E = 3D -3C +4C . . . . isolate E term
E = (3D +C)/4 . . . . . . . divide by 4 to find E
__
E = (3(-3, -4) +(1, 6))/4 = (-9+1, -12 +6)/4
E = (-2, -1.5)
The point is plotted in the attached graph.

Answers
Answer:
$5,000
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.
Solving our equation:
A = 2500(1 + (0.05 × 20)) = 5000
A = $5,000.00

?/1 If a test is worth 45 points, how many points would a student need to earn to get a score of 90%?
Answers
Answer:
40.5 points
Step-by-step explanation:
To start off, I would set up a proportion. You're trying to find how many points out of the total 45 would give you a 90%.
90% as a fraction would be [tex]\frac{90}{100}[/tex].
When you set the two equal to one another, you get this:
[tex]\frac{x}{45} = \frac{90}{100}[/tex]
The bottom numbers are the total amount of points, and the top is how many points a student got.
To solve for x, which is the number of points a student would need to earn, you can cross multiply.
After you do that, you should get:
100x = 4050
To isolate x, you can divide by 100 on both sides.
x = [tex]\frac{4050}{100}[/tex] = 40.5 points
To check your answer, all you have to do is divide.
40.5 ÷ 45 = 0.9
0.9 as a percent is 90%.

n=3+4n
subtract 4n from each side to get

B.

C.
13.2 feet x 8.2 feet
D.
10 feet x 8 feet
Answers
Answer:
A
Step-by-step explanation:
Percentage increment means the part of original value is added to the value. The new length of the living room is 14.4 feet long and new width of the living room is 1.6 feet long. The option A is the correct option.
What is the percentage of a number?Percentage of a number or ratio is fraction of hundred. It is expressed with the sign "%".
Given information-
The length of the living room is 12 feet.
The width of the living room is 8 feet.
The owner increases the 20 percent of length and 20% width.
Suppose new length is [tex]l[/tex] feet long. As the owner increases the 20 percent of length. Thus the new length will be sum of original length and the 20 percent of it. Hence,
[tex]l=12+\dfrac{20}{100}\times12 \\l=12+2.4\\l=14.4[/tex]
Thus the new length of the living room is 14.4 feet long.
Suppose new width is [tex]w[/tex] feet long. As the owner increases the 20 percent of width. Thus the new width will be sum of original width and the 20 percent of it. Hence,
[tex]w=8+\dfrac{20}{100}\times8 \\w=8+1.6\\w=9.6[/tex]
Thus the new width of the living room is 1.6 feet long.
Hence the new length of the living room is 14.4 feet long and new width of the living room is 1.6 feet long. The option A is the correct option.

Determine if the relation is a function if so state the domain and range
Answers
Answer:
Function - Yes
Domain - [-3,0,3,4]
Range - [1,2,2,5]
Step-by-step explanation:
In a function, x-values cannot repeat and in this relation, x's do not repeat, therefore it is a function. The domain is the x-values on the graph from least to greatest; so to find the domain, simply take the first value of each coordinate and order them from least to greatest. Then, the range is the y-values, so to find the range take the second value from each coordinate and order them from least to greatest.

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of EqualityStep-by-step explanation:
Step 1: Define
2x - 12 = -52
Step 2: Solve for x
Add 12 on both sides: 2x = -40Divide 2 on both sides: x = -20Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 2(-20) - 12 = -52Multiply: -40 - 12 = -52Subtract: -52 = -52Here we see that -52 does indeed equal -52.
∴ x = -20 is the solution to the equation.
Answer:
[tex]2x - 12 = - 52 \\ 2x = - 52 + 12 \\ 2x = - 40 \\ \boxed{x = - 20}[/tex]
-20 is the right answer.
