In the diagram, AC and PR are vertical lines, while CB is a horizontal line segment. If CR : RB = 2 : 3, what are the coordinates of point Q? A. (-2, -4) B. (-1, -5) C. (-3, -3) D. (0, -6)
Answer:
A. (-2,-4)
Step-by-step explanation:
If CR:RB is 2:3, and C is (-4,-7), then R is (-2,-7)
You can stop here because only A has the x value as -2.
If you want to look at the y value also, -4 is 2/5 of the way between -2 and -7, which has the same 2:3 proportion.

Andrea has a $25 gift card
to a art store. She buys four
canvases that are each the same
price. If she now has $2.20 on
her gift card,
what was the price of
each canvas?
Equation:
Solution:
Answer:
$5.70
Step-by-step explanation:
First we have to find out how much she spent. SO we do 25-2.20 which is 22.80. Then we have to divide by 4 since she buys four canvases that are the same price. SO 22.80/4=$5.70
Answer: 5.70
Step-by-step explanation:
Gift card = 25
Canvases = x
Since Andrea is buying four canvases, we can say that it is 4x.
Remaining balance = 2.20
Let's set up our equation. To set it up, we can write it like this
4x+2.20= 25
Now, subtract 2.20 on each side
4x = 22.8
Now divide, and you get around 5.70
So, each canvas was $5.70

Solve |3x + 9| + 6 = 6 Question 5 options: A) x = 3 B) x = 3 or x = –3 C) No solutions D) x = –3
Answer:
Hey there!
We have |3x + 9| + 6 = 6. Subtracting 6 from both sides gives us |3x + 9| = 0.
3x+9=0
3x=-9
x=-3
Hope this helps :)
Answer:
-3
Step-by-step explanation:
Subtracting 6 from both sides yields |3x + 9| = 0. For this to be true, 3x + 9 must be 0, and so x must be -3.

Answer:
x = 29/20 or x = 1.45
Step-by-step explanation:
6/x + 5/(4x) = 5
Multiply all terms by x and cancel.
6 + 5/4 = 5x
Combine terms on the left side of the equation.
29/4 = 5x
Divide both sides by 5.

Mr. Weaver invested part of his $6000 inheritance in an account that earns 4%
simple interest and the other part in an account that earns 7% simple interest.
How much did he invest in each account if the two accounts earned $360 after
the first year?
Answer:
Mr. Weaver invested $ 2,000 in the 4% simple interest account and $ 4,000 in the 7% simple interest account.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of the inheritance = $ 6,000
Interest rate of the first part = 4% simple
Interest rate of the second part = 7% simple
Interest of the accounts after the first year = $ 360
2. How much did he invest in each account?
For answering the question, we will use the following equation:
x = Amount invested in the first account
6,000 - x = Amount invested in the second account
0.04x + 0.07 * (6,000 - x) = 360
0.04x + 420 - 0.07x = 360
-0.03x = 360 - 420 (Subtracting 420 at both sides)
-0.03x = -60
x = -60/-0.03
x = 2,000 ⇒ 6,000 - x = 4,000
Mr. Weaver invested $ 2,000 in the 4% simple interest account and $ 4,000 in the 7% simple interest account.

According to the data from the U.S. Census Bureau for 1990-2009, the number of
commercially owned automobiles in the United States can be modeled by the function
A(x) = 1.4x – 130.6x² + 1831.3x + 128,141, where x is the number of years after 1990
and A(x) is the number of automobiles in thousands. The number of privately-owned
automobiles in the United States can be modeled by the function
P(x) = -x + 24.9x² – 177.9x + 1709.5, where x is the number of years after 1990 and
P(x) is the number of automobiles in thousands. Estimate the total number of automobiles
owned in 2005.
Answer: 130875 automobiles
Step-by-step explanation:
To estimate the total number of automobiles owned in 2005, let's first find the number of years
2005 - 1990 = 15 years
Given that the Commercially owned automobiles in the United States can be modeled by the function
A(x) = 1.4x – 130.6x² + 1831.3x + 128,141, where x is the number of years after 1990
and A(x) is the number of automobiles in thousands.
Substitute 15 for x in the function
A(x) = 1.4(15) – 130.6(15)² + 1831.3(15) + 128,141
A(x) = 21 - 29385 + 27469.5 + 128141
A(x) = 126246.5 automobiles
The number of privately-owned automobiles in the United States can be modeled by the function
P(x) = -x + 24.9x² – 177.9x + 1709.5, where x is the number of years after 1990
Substitute 15 for x in the function
P(x) = -(15) + 24.9(15)² – 177.9(15) + 1709.5
P(x) = -15 + 5602.5 - 2668.5 + 1709.5
P(x) = 4628.5 automobiles
The total automobile = A(x) + P(x)
Substitutes for A(x) and P(x)
The total automobile = 126246.5 + 4628.5
= 130875
Therefore, the total number of automobiles owned in 2005 is 130875 automobiles

A 2-digit number is increased by 36 when the digits are reversed. The sum of the digits is 10. What is the original number?
====================================================
Work Shown:
T = tens digit of the original number
U = units digit of the original number
U+T = 10 since the digits add to 10. Solve for U to get U = 10-T
10T+U = original number
10U+T = new number where digits are reversed
-----------
new number = (old number) + 36
10U+T = (10T+U)+36
10U+T = 10T+U+36
10(10-T)+T = 10T+10-T+36 ... plug in U = 10-T
100-10T+T = 10T+10-T+36
-9T+100 = 9T+46
100-46 = 9T+9T
54 = 18T
18T = 54
T = 54/18
T = 3 is the tens digit of the original number
U = 10-T
U = 10-3
U = 7 is the units digit of the original number
10T+U = 10*3+7 = 30+7 = 37 is the original number
73 is the reversed number.
73-37 = 36 is the difference, showing that 37 increased by 36 leads to 73. The answer is confirmed.

(x, y) - (x + 5, y + 3)
(x,y) - (x-3, y + 5)
O (x,y) - (x + 3, y + 5)
Answer:
[tex](x,y)\rightarrow(x-3,y+5)[/tex]
Step-by-step explanation:
"5 units up" would be "5 added to the current y-value".
"3 units to the left" would be "3 subtracted from the current x-value".
So, the translation rule is:
[tex](x,y)\rightarrow(x-3,y+5)[/tex]
Therefore, Option C should be the correct answer.
Brainilest Appreciated.
The Rule describes the translation is : (x, y) - (x - 3, y + 5)
We have a rectangle on a coordinate plane is translated 5 units up and 3 units to the left.
We have to determine which of the given rules describes the translation.
A point P(3, 3) is translated 10 units up and 4 units to the left. What will be the new coordinates of this point P?The new coordinates of this point P will be - P'( - 1, 13).
According to the question, we have -
Upward translation = 5 units
When the upward translation will take place then, each and every point that lies on that rectangle will have its y - coordinate shifted upwards by +5 units.
Leftward Translation = 3 units
When the leftward translation will take place then, each and every point that lies on that rectangle will have its x - coordinate shifted by - 3 units
to the left.
Hence, rule describes the translation is : (x, y) - (x - 3, y + 5).

If you're good at bearings pls help mee
What is the true bearing of Milton from Binji?
The leading 0 is important with true bearings. Any true bearing must be three digits.
======================================================
Explanation:
It's not stated, but I'm assuming that Binji and Congo form a flat horizontal line.
B = Binji's location
M = Milton's location
C = Congo's location
The given angles are M = 76 and C = 38. The missing angle is
B = 180-M-C
B = 180-76-38
B = 66
Subtract this from 90 to get 90-66 = 24
The true bearing of Milton from Binji is 024 degrees
In other words, if you are at Binji's location, face directly north, and turn 24 degrees clockwise (turn to the right), then you'll be facing Milton's location.
-------------
Extra info:
In terms of compass notation, the true bearing of 024 degrees converts to N 24 E. This is the same as E 66 N, though convention usually has north used more often (since it's a common reference point with compasses).
N 24 E = start facing north, turn 24 degrees to the east
E 66 N = start facing east, turn 66 degrees to the north

Using everyday knowledge, indicate whether the if-then statements are correct forward-only or both forward and reverse.
Statement 1: If Bo is Mel's sibling, then Melis Bo's sibling.
Statement 2: If the sprinklers are on, then the grass is wet.
Answer:
1. Both forward and backward
2. Only forward
Step-by-step explanation:
The reason Statement 1 can be both forward and reverse is because is Bo and Mel are related then it will word forward and backward.
The reason Statement 2 can be only forward is because is the sprinklers are on then the grass is wet will work since it is saying ONLY the sprinklers are on. If it is reverse and the grass is wet if the sprinklers are ONLY on than that is false since if it rains than the grass can also be wet. So there are multiple ways that the grass can be wet hence the answers.
