1. In the diagram, AA'B'C' is an image of AABC. Which rule describes this translation?
O(x, y) → (x-5,y-3)
O(x, y) + (x + 5, y + 3)
O(x,y) → (x-3, y-5)
O(x, y) (x+3, y + 5)
Answers
Option B: [tex](x, y) \rightarrow(x+5, y+3)[/tex] is the rule for the translation
Explanation:
The coordinates of A,B,C are [tex](-3,2)[/tex] ,[tex](-3,-3)[/tex] , [tex](0,-2)[/tex]
The coordinates of A',B',C' are [tex](2,5)[/tex] , [tex](2,0)[/tex] , [tex](5,1)[/tex]
We need to determine the rule for the translation
The rule for the translation is given by
[tex]P(x, y) \rightarrow P^{\prime}(x+a, y+b)[/tex]
Let us determine the translation from A to A'
[tex]A(-3,2)\rightarrow A^{\prime}(-3+a, 2+b)\rightarrow A'(2,5)[/tex]
Thus, we have,
[tex]\begin{aligned}-3+a &=2 \\a &=5\end{aligned}[/tex] and [tex]\begin{array}{r}2+b=5 \\b=3\end{array}[/tex]
Thus, the rule is given by
[tex](x, y) \rightarrow(x+5, y+3)[/tex]
Therefore, Option B is the correct answer.

Triangle ADE is similar to triangle ABC. Which statement is TRUE concerning the slope of the line formed by the hypotenuse of each triangle? A) EA DE = CB AC B) DE EA = CB AC C) DE EA = AC CB D) EA DE = AC CB
Answers
Answer:
[tex]B) \frac{DE }{EA} =\frac{CB}{AC}[/tex]
Step-by-step explanation:
If ant two given triangles are SIMILAR, then they have equal corresponding angles and their corresponding sides are PROPORTIONAL.
For example: if Δ ABC ≈ Δ PQR, then
∠A = ∠P , ∠B = ∠Q and ∠C = ∠R
and [tex]\frac{AB}{PQ} = \frac{BC}{QR} = \frac{AC}{PR}[/tex]
Now, here given: Δ ADE ≈ Δ ABC
Then by the SIMILAR postulate their corresponding angles are equal and their corresponding sides are Proportional.
[tex]\implies \frac{AD}{AB} = \frac{DE}{BC} = \frac{AE}{AC}[/tex] ............. (1)
Consider from above:
[tex]\frac{DE}{BC} = \frac{AE}{AC}\\\implies \frac{DE}{AE} = \frac{BC}{AC}[/tex] ............. (2)
Here, the given options are:
[tex]A) \frac{EA }{DE} =\frac{CB}{AC}[/tex] FALSE
[tex]B) \frac{DE }{EA} =\frac{CB}{AC}[/tex] TRUE (from 2)
[tex]C) \frac{DE }{EA} =\frac{AC}{CB}[/tex] FALSE

6. The population of a town is 680 000 correct to the nearest 10 000. Write down
(a) The least possible population of the town.
(b) The greatest possible population of the town.
Answers
Answer:
a) 675 000
b) 685 000
Step-by-step explanation:
The population of a town is 680 000 correct to the nearest 10 000.
a) To find it lower bound, we level of accuracy by 2 and then subtract from 680 000
The lower bound is:
680 000-5000=675,000
Therefore the least possible population of the town is 675 000
b) We repeat the same process to find the upper bound
680 000+5000=685,000

The solutions to f(x) = 64 is x = 7 and x = –7.
Solution:
Given data:
[tex]$f(x)=x^{2}+15[/tex] and [tex]f(x)=64[/tex]
To find the solutions when f(x) = 64.
Both are equations of f(x), so equate the given equations, we get
[tex]x^2+15=64[/tex]
Subtract 15 from both sides of the equation.
[tex]x^2+15-15=64-15[/tex]
[tex]x^2=49[/tex]
49 can be written as 7².
[tex]x^2=7^2[/tex]
Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.

Cost of paint brushes= Total cost - cost of paint
= 71 - 50 = $21
No.ofpaint brushes =21/3.50 = 21*10/3.5*10
= 210/35 = 6
Answer:
Natasha paid $6 per paintbrush
Step-by-step explanation:
Cost for paint brusheswe can make use of variables
p = paint
b = brushes
bought paintbrushes and paint for a total of $71. . The brushes cost $3.50 per brush and the paint cost $50
we can create an equation from the information
3.5b + 50p = 71
since 1 paint is bought
3.5 b + 50 (1) = 71
3.5b = 71 - 50
3.5b = 21
b = 21/3.5
b = 6

-8x+5y=43
-8x+4y=36
Answers
Answer:
[tex]x=-1\\y=7[/tex]
Step-by-step explanation:
Given equations:
[tex]-8x+5y=43[/tex] Equation:1
[tex]-8x+4y=36[/tex] Equation:2
As the coefficients of 'x' are same which will eliminate the terms of 'x':
Subtracting Equation:2 From Equation:1
[tex]-8x+5y-(-8x+4y)=43-36\\\\-8x+5y+8x-4y=7\\\\5y-4y=7\\\\y=7[/tex]
Putting value of 'y' in either equation:1 or 2
Putting y=7 in equation:2
[tex]-8x+4y=36[/tex]
[tex]-8x+4(7)=36\\\\-8x+28=36[/tex]
Subtracting '28' from both side:
[tex]-8x+28-28=36-28\\\\-8x=8\\[/tex]
Changing the sides:
[tex]8x=-8[/tex]
[tex]x=\frac{-8}{8} \\\\x=-1[/tex]
The values are :

z varies directly as x². If z=8 when x=2, find z when x=7
Answers
Answer:
98
Step-by-step explaination:
For this question, it is a direct variation. Hence, the equation would be formed accordingly, and the constant k would also be used.
z varies directly as x²
z= kx² where k is the constant
z = 8
x = 2
Putting the figures in the equation, we have
8=2²(k)
8= 4k
Dividing both sides by 4, we have
k = 8/4
k = 2
Solving for z now, we substitute k with 2. And x with 7
z=kx²
z = 2(7²)
z= 2(49)
z= 98
If it were indirect variation, the constant would have been 1/k. We also have other types of variation, Indirect variation, partial variation and joint variation.

A cylindrical water tank has a radius of 5 feet and a height of 10 feet. The volume of water in the tank is 565.2 cubic feet.
What percent of the tanks volume is filled with water?
Answers
About 71.96% of the cylindrical water tank, with a radius of 5 feet and a height of 10 feet, is filled with water when it contains 565.2 cubic feet of water.
To determine what percent of the tank's volume is filled with water, we must first calculate the total volume of the cylindrical tank using the formula for the volume of a cylinder: V = (pi)r²h. Here, the radius r is 5 feet, and the height h is 10 feet.
The total volume V of the tank is:
V = (pi)(5 feet)²(10 feet) = 3.14159 times 25 times 10 = 785.398 cubic feet
Now, since the volume of water in the tank is given as 565.2 cubic feet, we can calculate the percent of the tank's volume that is filled with water by dividing the volume of water by the total volume of the tank and then multiplying by 100 to convert to a percentage. So the calculation becomes:
Percent filled = ([tex]\frac{565.2}{785.398}[/tex]) times 100
Percent filled approx 71.96%
Therefore, about 71.96% of the tank's volume is filled with water.

Marcy would not reveal her equation, but she said that she could multiply the left side by 4 and the right side by 8 and still maintain its balance. mr. kim verified she was correct . What is Marcys equation
Answers
Answer:
4x=8y
Step-by-step explanation:
Ok so a number multiplied by 4 equal a number multiplied by 8.
Both numbers can't have the same variable because if they had the same varable that means they are the same number which in that case means Marcy is wrong but we know she is right because Mr.Kim said so.
let's plug in numbers. If they had the same variable it would be:-4x=8x
let x=2, 4(2)=8(2)
8=16 not true
if the variables were not the same:-4x=8y
let x=4
let y=2 4(4)=8(2)
16=16 true
The sum of two numbers is 14. The larger number minus three times the lesser number is -2. What is the lesser number?
A) 10
B) 12
C) 4
D) 3
Answers
Answer:
c) 4
Step-by-step explanation:
The sum of two numbers is 14. The larger number minus three times the lesser number is -2
To solve this question, we need to write the statement mathematically;
Let the two numbers be x and y
"The sum of two numbers is 14" can be mathematically written as x+y = 14
and
"The larger number minus three times the lesser number is -2" can be mathematically written as x - 3y = -2
x + y = 14 ------------------(1)
x - 3y= -2 -------------------(2)
Subtract equation (2) from equation (1)
[x - x = 0 y - (-3y)=4y 14-(-2)=16]
4y = 16
To get the value of y divide both-side of the equation by 4
4y/4 = 16/4
y = 4
Substitute y=4 into equation (1)
x + y =14
x +4 =14
Subtract 4 from both-side of the equation
x + 4 -4 = 10]-4
x = 10
x=10 and y =4
Therefore the lesser number is 4

The Pythagorean Theorem was used on a right triangle with sides of length 4 to find that the hypotenuse has a length approximately equal to 5.7.
Explanation:Here, your task is to apply the Pythagorean Theorem which states that in a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). In this case, both a and b are given as 4. We can therefore calculate c as follows:
First, square the lengths of both a and b: 4^2 + 4^2 = 16 + 16Combine like terms: 16 + 16 = 32Find the square root of the sum to find c: sqrt(32) is approximately 5.7 (to the nearest tenth).Learn more about Pythagorean Theorem here:https://brainly.com/question/19649203
