Answer:
[tex]\frac{4}{3}[/tex]hrs/house
Step-by-step explanation:
Rate is the amount of work done per unit of time;
Let Cara's rate = C
Let Jena's rate = J
C + J = 4 ------ i
Now;
Working alone:
Jena takes twice as long as Cara
J = 2C ---- i
How long does it take Cara to clean a house alone
C + J = 4
J = 2C
C + 2C = 4
3C = 4
C = [tex]\frac{4}{3}[/tex]hrs/house

ABC is a straight line.
The length of AB is four times the length of BC.
AC = 75 cm.
Work out the length of AB.
Answer:
60
Step-by-step explanation:
so 4 of BC will make a AB, so AC =5 of BC =75
therefore BC=75/5=15
If BC=15 and AB=4*BC=4*15=60

what is the question?
Step-by-step explanation:
The value of the function f(4) is 11.
We have,
To find the value of f(4) for the given function f(x) = 2x + 3,
We substitute x = 4 into the function.
f(4) = 2(4) + 3
= 8 + 3
= 11
We can also see that,
4 is the input and 11 is the output of the function.
Therefore,
The value of the function f(4) is 11.

4 (6 – x) + 4 = 2 (3x + 1) - 6
Answer:
x = 2.4
Step-by-step explanation:
Simplify.
24 - 4x + 4 = 6x + 2 - 6
Combine like terms (24 + 4 = 28, sorry for the confusion!)
28 - 4x = 6x - 4
Add x and add 4 to both sides.
10x = 32
x = 3.2

Which two answer choices below would give you a value of 3 times larger than (820 + 220)?
A) 3(820 + 220)
B) 3(820) + 2(220)
C) 2460 + 660
D) 820 x 220 x 3
The expression that gives you a value of 3 times larger than (820 + 220) are:
3(820 + 220)
2460 + 660
Options A and C are the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(820 + 220)
= 1040
Now,
3 x 1040
= 3120
Now,
A)
3(820 + 220)
= 3 x 1040
= 3120
B)
3(820) + 2(220)
= 2460 + 440
= 2900
C)
2460 + 660
= 3120
D)
820 x 220 x 3
= 541200
Thus,
3(820 + 220) and 2460 + 660 give the value of 3 times larger than
(820 + 220).

The graph the formula representing the compound interest will be exponential function.
What is graph?
In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".
Given is the equation representing compound interest.
The equation representing the compound interest is -
C = P( 1 + r/n )ⁿˣ
Where -
[P] is principle amount.
[r] is rate.
[x] is time.
The exponential function is eˣ, where [x] is a variable. Similarly, we can graph the formula representing the compound interest as shown in the figure attached. The graph will be exponential in nature.
Therefore, the graph the formula representing the compound interest will be exponential function.

Which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of 1/3?
Answer:
Option 2: [tex]y - 2 = \frac{1}{3}(x-3)[/tex] is the correct answer.
Step-by-step explanation:
The equation of a line with given point(x1,y1) and slope m is given by:
[tex]y-y_1 = m(x-x_1)[/tex]
The line passes through (x1,y1)
Given
[tex](x_1,y_1) = (3,2)\\m = \frac{1}{3}[/tex]
=> x1 = 3
=> y1 = 2
Putting the values of x1, y1 and slope(m) in the point-slope form, the equation of line is:
[tex]y - 2 = \frac{1}{3}(x-3)[/tex]
Hence,
Option 2: [tex]y - 2 = \frac{1}{3}(x-3)[/tex] is the correct answer.

What is the image point of ( 8 , − 2 ) after a translation right 5 units and up 2 units?
Answer:13,0
Step-by-step explanation:
A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points. The coordinates of point (8,−2) after translation will be (13,2) and (13,4).
What are coordinates?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
The coordinates of a point (x,y) can be translated by right 5 units and up 2 units as,
Translation right by 5 units → (x+5, y)Translation up by 2 units → (x+5, y+2)Now, the given coordinate (8, -2) can be translated as shown below,
Translation right by 5 units → (8+5, 2) = (13, 2)Translation up by 2 units → (8+5, 2+2) = (13, 4)Hence, the coordinates of point (8,−2) after translation will be (13,2) and (13,4).

Answer: B
Step-by-step explanation:
To find the result of the dilation, multiply each x and y coordinate by the scale factor, which in this case, is 1.5. I started out with the coordinate P, which had an original coordinate of (-2,1). In this case, I multiplied -2 by 1.5, and 1 by 1.5 to get (-3, 1.5). Since this is multiple choice, the only one with P as (-3, 1.5) is B, so we don't have to check the others.
The answer is B.
1) Apply dilation
2)Find each one x coordinate (x,y)
3) Find the y coordinate for each one
4) See which one matches your answers
