Plot the image of point Q under the translation (x, y) + (x - 3, y + 4).
Answer:
( 2, -1 )
Step-by-step explanation:
The image of the assumed point Q(2, 3)) under the translation is Q'(-1, 7).
What is Translation?Translation is a type of transformation of geometrical figures. After translation, the original figure is shifted from a place to another place without affecting it's size.
Translation of a point (x, y) indicates that the point is moved x units along the X axis and y units along the Y axis,
Here we have to translate the point Q(2, 3).
Point (x, y) is translated as (x - 3, y + 4).
That is the point (x, y) moves 3 units to the left along the X axis and 4 units upwards along the Y axis.
Q(2, 3) after the translation becomes,
Q'(2 - 3, 3 + 4) = Q'(-1, 7)
Hence the point Q(2, 3) under the translation (x - 3, y + 4) is the point Q'(-1, 7).

The length of a rectangle is (5x − 1) cm and the width is (11 − 2x) cm. If the perimeter of the rectangle is 44 centimeters, what is the area of the rectangle?
Answer:
57 cm²
Step-by-step explanation
l = length
w = width
p = perimeter
(5x - 1) = length
(11 - 2x) = width
44 = perimeter
Formula for the perimeter of a rectangle:
l + l + w + w
2l + 2w = p
Substitute the variables for the length and width with the values given to you by the problem, then solve.
2(5x - 1) + 2(11 - 2x) = 44
(10x - 2) + (22 - 4x) = 44 (Distributive property)
6x + 20 = 44
6x = 24
x = 4
Plug x = 4 back into the length and width.
Length = (5x - 1), (5(4) - 1), (19)
Width = (11 - 2x), (11 - 2(4)), (3)
Area for a rectangle: Length × Width = Area.
19 × 3 = 57 cm²
This is all in cm so answer with cm²

Answer:
FG = 9BF = 27GD = 7CG = 14Step-by-step explanation:
Point G is the intersection of medians, the centroid. That point divides each median into parts with a 2:1 ratio. The "2" part is the distance between the centroid and the vertex. The "1" part is the distance between the centroid and the side.
FG : GB : BF = 1 : 2 : 3 = 9 : 18 : 27 . . . . . where 18 is given
GD : CG : CD = 1 : 2 : 3 = 7 : 14 : 21 . . . . . where 21 is given

How do you decide in what way to reorder the terms of expression when simplifying it
We use the PEMDAS to reorder the terms of expression when simplifying it.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
We use the PEMDAS to reorder the terms of expression when simplifying it.
The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
Therefore, use PEMDAS to simplify any expression.

Brayden just lit a new candle and then let it burn all the way down to nothing. The
candle burned at a rate of 0.75 inches per hour and its initial length was 6 inches.
Write an equation for L, in terms of t, representing the length of the candle
remaining unburned, in inches, t hours after the candle was lit.
Answer:
L = -0.75t + 6
Step-by-step explanation:
L = length (this is what equation you are looking to solve for
-0.75t because the candle burns at 0.75 in per hour so the value decreases, hence the (-)
+6 because the candle has a positive value of 6 inches to begin with
The standard form of what you are writing is called slope intercept form y = mx + b, learn it because it is very important for future math.
The equation of the candle remaining unburned at any given time is L(t) = 6 - 0.75t.
What is a function ?A function is a set of values of the dependent variable for specified independent variable.
According to the given question Brayden just lit a new candle and then let it burn all the way down to nothing.
The candle burned at a rate of 0.75 inches per hour and its initial length was 6 inches we have to write an equation for L in terms of t where t represents time in hours and L(t) represents length of the candle remain unburned.
∴ L(t) = 6 - 0.75t.
At t = 0 the length of the unburned candle L(t) will be 6 inches and at t = 8 L(t) will be 0,So the candle can burn for 8 hours.

A baking mix consists of powdered milk, sugar, and flour in a ratio of 3:4:13.
How many pounds of each ingredient do you need to make 4 lb of baking mix?
Answer:
Sugar = 0.8 lb
milk = 0.6 lb
Flour = 2.6 lb
Step-by-step explanation:
Firstly, we add the ratios = 3 + 4 + 13 = 20
For milk, we have 3/20 * 4 = 12/20 = 0.6 lb
For sugar l, we have 4/20 * 4 = 16/20 = 0.8 lb
For flour = 13/20 * 4 = 52/20 = 2.6
You will need:
[tex]Milk = 0.6 $ lb\\Sugar = 0.8 $ lb\\Flour = 2.6 $ lb[/tex]
Given:
Milk : Sugar : Flour = 3 : 4 : 13
To find the number of pounds of each ingredient required to produce 4 lb of baking mix, solve as follows:
Amount of each ingredient needed = ratio of each ingredient / total ratio value x 4 lb
Thus:
Total ratio value = [tex]3 + 4 + 13 = 20[/tex]
Amount of milk needed = [tex]\frac{3}{20} \times 4 = 0.6 $ lb[/tex]
Amount of Sugar needed = [tex]\frac{4}{20} \times 4 = 0.8 $ lb[/tex]
Amount of Flour needed = [tex]\frac{13}{20} \times 4 = 2.6 $ lb[/tex]
Therefore, you will need the follow amounts to make 4 lb of baking mix:
[tex]Milk = 0.6 $ lb\\Sugar = 0.8 $ lb\\Flour = 2.6 $ lb[/tex]

Rita just bought a car for 15,000. She paid 20% down and borrowed the remainder at an annual interest rate of 9.0%. The loan will be repaid over four years with monthly payments of $298.62. How much is rita's down payment and how much did she borrow?
Answer:
Rita's down payment is $3000 and she borrowed $12000.
Step-by-step explanation:
The cost of the car is $15000.
Given that she paid 20% down and borrowed the remainder.
So, Rita's down payment= 20% of $15000
[tex]=\frac{20}{100}\times 15000[/tex]
= $3000
As she borrowed the remainder cost, so,
the borrowed amount = 15000-3000
= $12000
Hence, Rita's down payment is $3000 and she borrowed $12000.
If n divided by m equals 7/8,
what does m divided by n equal?
Step-by-step explanation:
1,
It is found that m divided by n is equal to 8/7.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, a/ b = a divided in b equal parts.
If n divided by m equals 7/8, then m divided by n equal.
n / m = 7/8
Then m/n = 8/7
Therefore, m divided by n is equal to 8/7.
