Step-by-step explanation:
Which reflection will produce an image of ARST with a
vertex at (2, -3)?
O a reflection of ARST across the x-axis
O a reflection of ARST across the y-axis
O a reflection of ARST across the line y = x
O a reflection of ARST across the line y=-x
Answer: D- a reflection of ^RST across the line y=-x
Step-by-step explanation:
The solution is, O a reflection of RST across the line y=-x, is the reflection which will produce an image of RST with a vertex at (2, -3).
What is reflection?Reflection is a type of transformation that flips a shape in a mirror line (also called a line of reflection) so that each point is the same distance from the mirror line as its reflected point.
here, we have,
from the given figure,
we get,
Triangle RST has,
vertex R ( -1,3)
vertex S ( 3, -2)
vertex t (1, -4)
now we know that,
the rule of a reflection across the line y=-x,
(x, y) ⇒ (-x, -y)
so, we get, here,
vertex S ( 3, -2) ⇒ vertex at (2, -3)
so, there is O a reflection of RST across the line y=-x.

The function f(x) = 0.5x + 3 is used to estimate the number of pounds of potatoes a caterer plans to make depending on the number of
people being served, X. The mathematical domain for the function is the set of real numbers.
Which statement describes the limitation for the reasonable domain compared to the mathematical domain?
Options:
The reasonable domain contains only positive real numbers.
The reasonable domain contains only positive whole numbers.
The reasonable domain contains only real numbers greater than 3.
The reasonable domain contains only rational numbers greater than 3.
Answer:
(b) The reasonable domain contains only positive whole numbers.
Step-by-step explanation:
Given
[tex]f(x) = 0.5x + 3[/tex]
Required
True statement about the limitation of the domain
Since the domain (x) represents people, then it must be a positive whole numbers
This eliminates options (a) and (c)
The range of the function is not given. So, we can assume that any number of people can be present.
This eliminates option (d).
Hence: (b) answers the question

Answer:
b. 5z-10 = 5(z-2) c. c-2c^2= c(1-2c) d. r+r+r+r= r(1+1+1+1)= 4r e. 2x-(1/2) = (1/2)(4x-1)
Explanation:
you just need to find a common factor that you can divide out of each term. ex. with the 5z-10 both 5z and 10 are divisible by 5, so you can factor that out. to check the answers just multiply it. if you still don't get it, look up "factoring binomials"
A school offered its students an optional field trip. If 15 or fewer students went on the field trip, the charge for each student would be $11.50. If more than 15 students chose to go on the field trip, the charge for each student would be $10.25. 18 students opted to go on the tour, but each pre-paid $11,50. The students agreed to put the extra amount toward dinner on the trip. How much total money will be put toward dinner on the trip?

A student bought some markers in a pads of paper if the marker cost $2 each in the pads of paper cost $4 each he brought a items and all and spent $26 how many markers and how many pads of paper did he buy?
Answer:
$4
Step-by-step explanation:
We need to set up an algebraic expression to solve this problem:
Let n= cost of a notepad
Let p= cost of a pen
First set up an expression for Cynthia's purchase:
cost of notepads*number of notepads + cost of pens*number of pens = total cost
n*2 + p*3 = 40.30
Rewrite as:
2n + 3p = 40.30
Next, set up an expression for Annie's purchase:
Here we will be using the same variables
n*3 + p*5 = 61
Rewrite as:
3n + 5p =61
Now, set up a system of equations:
2n + 3p = 40.30
3n + 5p =61
A system of equations can be solved in several ways, here I will use the addition/elimination method
For this method one of the variables must be able to be eliminated
Step 1: Pick a variable to eliminate
Here I will eliminate n
Step 2: make the selected variables in the equations equal and opposite so that they cancel out when the equations are added together
(2n + 3p = 40.30)(-3)
(3n + 5p =61)(2)
-6n - 9p = -120.90
6n + 10p = 122
Step 3: add vertically
-6n - 9p = -120.90
6n + 10p = 122
p = 1.10
Step 4: Figure out the other variable by inputting the answer you just got back into the original equation
2n + 3(1.10) = 40.30
2n + 3.30 = 40.30
-3.30 37
2n = 37
/2 /2
n = 18.5
One notebook = $18.50
One pen= $1.10
18.50+1.10= $19.60
2nd step
We must first set up an algebraic expression
total=15 pencils
total=9 pens
The total amount is the price of one pencil*15
To figure out one pencil:
10 pencils are $24
1 pencil is $2.40
Total= $36
9 pens = 36
Therefore 1 pen is $4
Here are the diameters of four coins. A dime rolls 41.8 cm. How many rotations did it make?
Will give brainliest,
Answer:
i believe the answer is 10.5
Step-by-step explanation:
dime = 3.14 (1.8) =5.62 cm
Since the coin rolled about 10.5 cm in 4 rotations, it means that the circumference of the coin (x) multiplied by 5 is equal to the distance rolled.
4x=41.8
x =41.8/4 =10.5cm
good luck :)

Savannah had 400 chocolate chips. She saved x chips for a garnish, and mixed the rest of the chocolate chips evenly into 3 pans of brownies.
How many chocolate chips were in each pan of brownies?
Answer:
( 400-x)/3
Step-by-step explanation:
Total chocolate chips Savannah had = 400
Number of chocolate chips she saved for garnishing =x
Number of chocolate chips remain = 400-x
Number of brownie pans = 3
Chocolate chips were spread evenly in 3 pans,
Chocolate chips were in each pan of brownies =( 400-x)/3
The following data points represent the number of chicken nuggets on each family member's plate.
1,3,0, 6, ?
If the mean of the data set is 3 chicken nuggets, find the missing number of chicken nuggets.
nuggets
Answer:
The missing number of chicken nuggets is 5.
Step-by-step explanation:
To find the mean of this data set, we must add every number together, then divide the sum by how many numbers are present.
Like this,
1 + 3 + 0 + 6 = 10
10 / 4 = 2.5
There are 4 present numbers in this data set, and one is missing.
Since the only number divided by 5 that would give you a quotient of 3 is 15, the missing number is 5.
Because,
1 + 3 + 0 + 6 + 5 = 15
15 / 5 = 3
Therefore, 5 is the missing number of the data set.

How do I find the area of this?
Answer:
Area of the given right triangle = 24 square units.
Step-by-step explanation:
Given triangle in the picture is a right triangle.
Area of a right triangle is given by,
Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
Height of the given triangle = 8 unit
Base of the given triangle = 6 unit
Area of the triangle = [tex]\frac{1}{2}(6)(8)[/tex]
= 24 square units
Therefore, area of the given right triangle is 24 square units.

a) What is the diameter of bacteria species B in metres?
b) Based on your answer in (a), is the value obtained less than, greater than or equal to 1 nanometre?
Answer:
Bacteria A has diameter size of 1 micrometer = 1 × 10⁻⁶ m
a) B is 1× 10⁻³ size of A:
1 × 10⁻⁶ * 1 × 10⁻³ = 1 × 10⁻⁹ mb) 1 nanometer = 1 × 10⁻⁹ m

Which Equation best matches the graph shown below?
Answer:
.2(x+1)(x+5)
Step-by-step explanation:
Well first lets start with the x intercepts which are -1 and negative 5 so the equation must be either -0.2(x+1)(x+5) or .2(x+1)(x+5)
Notice how the graph is going upwards this means the number in front of the equation -.2 or .2 must be positive making .2(x+1)(x+5) this is because if .2 was negative the graph would be going downwards
