Answer:
The order of ordered pairs of a function and its inverse reverse. The graph of the inverse of this function passes through the points (2,-1), (6,0), (-4,3).
Explanation:
I just took the test.
As per the graph, the non-invertible functions pass through the point of (-1, 2)), (0,6), and (3, - 4).
The inverse of the function on the graph will be depicted by the Y = X. The graph of the inverse passes through the vertical line test for the inverse function.

In order to add or subtract matrices, what requirement must the matrices have?
Answer:
The must have the same dimension
Step-by-step explanation:
Two matrice may be added or subtracted only if they have the same dimension; that is, they must have the same number of rows and columns.
When we add 2 matrices the matrices should be of the same size and same dimension
A matrix is referred to as the collection of numbers or variables arranged in a set of rows and columns, where each number or variable is referred to as an "element".
In order to perform addition or subtraction on matrices, they must be of the same size and dimension ie. two matrices must have an equal number of rows and columns. Simply add or subtract the numbers in each corresponding position of the first matrix with the number in the same position of the second matrix. The sum of two matrices A and B will be a matrix that has the same number of rows and columns as A and B. The sum of A and B denoted A + B, is computed by adding corresponding elements of A and B
A=[tex]\left[\begin{array}{ccc}a1&a2\\a3&a4\end{array}\right][/tex] B=[tex]\left[\begin{array}{ccc}b1&b2\\b3&b4\end{array}\right][/tex]

1. 7.35 x 10 6 – 9.42 x 10 8
2. 3.14 x 10 -3+1.59 x 10 -1
3. (2 .8x 10 -9 )(4.75 x 10 -3 )
Answer:
1) -9.3465 × 10^8
2) 1.6214 × 10^-1
3) 1.33 × 10^-11
Explanation:
When solving arithmetic operations of numbers in scientific notation, there is a strategy that can be used.
First recognize the quotient(division) between the size of the numbers indicated by a multiple of 10 to a certain power. Remember, taking the quotients of like numbers with different powers is the subtraction of powers.
For example, to solve the first expression (problem one):
7.35 x 10^6 – 9.42 x 10^8
Divide 10^8 by 10^6 to get 10^2
So
it is like subtracting 7.35 and 9.42 × 10^2 which is 7.35 - 942, then once this expression is solved, multiply by the lowest multiple of 10 which is 10^6.
7.35 - 942 = -934.65 → -934.65 × 10^6 = (-9.3465 × 10^2) × 10^6 = -9.3465 × 10^8.
Long subtraction may need to be used when dealing with numbers that are far apart. Likewise long addition multiplication or division is used for very big or small numbers.
Anyway for the second expression (problem 2)
Addition in my opinion is much easier because it is really just adding on the bigger number. Subtraction may take a little longer but both processes are all based on the bigger number or the number with the greatest power of the multiple 10.
So 3.14 × 10^-3 + 1.59 × 10^-1
The quotient between 10^-1 and 10^-3 is the the difference between -3 and -1 which is 10^2
So again it is like adding 3.14 and 1.59 × 10^2 which is 3.14 + 159 = 162.14 = 1.6214 × 10^2. Now use the multiple of 10 with the largest contrast which is 10^-3 so 1.6214 × 10^2 × 10^-3 = 1.6214 × 10^(2-3) = 1.6214 × 10^-1.

You have the option to deposit $6500 into an account that pays 3.25% interest, compounded quarterly OR to deposit your money into an account that pays the same interest rate but compounds continuously. Which option yields you more money after 5 years and how much more?
OPTIONS:
Compounded quarterly, $4809.13
Compounded quarterly, $416.23
Compounded continuously, $5.02
Compounded continuously, $878.52
9514 1404 393
Answer:
Compounded continuously, $5,02
Step-by-step explanation:
Compounded quarterly, the amount in the account will be ...
A = 6500(1 +.0325/4)^(4·5) ≈ 7641.89
Compounded continuously, the amount in the account will be ...
A = 6500e^(.0325·5) = 7646.91
So, the account compounding continuously has the higher yield, by the amount of ...
$7646.91 -7641.89 = $5.02

Which of these equations, when solved, gives a different value of x than the other three?
9.1 = -0.2x + 10
10 = 9.1 + 0.2x
10 – 0.2x = 9.1
9.1 – 10 = 0.2x
Answer: 9.1-10=0.2x
Step-by-step explanation:
9.1 = −0.2x + 10
−0.2x + 10 = 9.1
−0.2x + 10 − 10 = 9.1 −10
−0.2x = −0.9
−0.2x / −0.2 = −0.9 / −0.2
x=4.5
10 = 9.1 + 0.2x
10 = 0.2x + 9.1
0.2x + 9.1 = 10
0.2x + 9.1 − 9.1 = 10 − 9.1
0.2x = 0.9
0.2x / 0.2 = 0.9 / 0.2
x=4.5
10 − 0.2x = 9.1
10 + (−0.2x) = 9.1
−0.2x + 10 = 9.1
−0.2x + 10 − 10 = 9.1 − 10
−0.2x = −0.9
−0.2x / −0.2 = −0.9 / −0.2
x=4.5
9.1 - 10 = 0.2x
-0.9 = 0.2x
-0.9 / 0.2 = 0.2x / 0.2
x= -4.5
Answer:
the answer is d/9.1 – 10 = 0.2x

GYM MEMBERSHIP The cost of a gym membership is $75 plus $30 per month. The equation that represents this equation is y=30 x+75, where x is the number of months and y is the cost. Find and interpret f(12).
Answer:
x = no.of months
y = cost
f(12) = 30x+75
f(12) = 30(12)+75
f(12) = 360+75
f(12) = 435
Therefore it cost him $435 in 12 months.
It will cost him $435 in 12 months or the value of f(12) is $435.
It is given that cost of gym membership is $75 plus $30 per month and the equation representing it is y = 30x + 75.
We have to find the value of f(12) or cost of gym after 12 months.
What do you mean by domain and ranges of a function ?
The domain is set of all values for which the function is defined and the range of the function is set of all values that function takes.
As per the question ;
The cost of gym membership is $75 plus $30 per month.
and
The given equation is ;
y = 30 x + 75
where ;
x = no. of months
and
y = cost
So , we can find out the value of f(12) as ; y = f(x) = f(12)
⇒ f(12) = 30x + 75
⇒ f(12) =( 30 × 12 ) + 75
⇒ f(12) = 360 + 75
⇒ f(12) = 435
Thus , it will cost him $435 in 12 months or the value of f(12) is $435.

Emma borrowed $89.40 from her sister. She determines that she can pay her back the total over six months. Which number reflects the monthly change in her balance?
Answer:
$14.9
Step-by-step explanation:
Step one:
given data
we are told that Emma borrowed $89.40 from her sister to pay her back in 6 months.
let us solve for the amount she is to pay her sister every month.
amount to be paid per month= 89.40/6
=$14.9
So that every month she pays back her sister $14.9
we don't know her balance but every month there will be a deduction.
Hence the monthly change in her balance is reflected by a deduction of $14.9
If z is a positive integer, does 4+3(2z-5) represent a number that is greater than, less than, or equal to 2(3z-4)?
Answer:
Step-by-step explanation:
4 + 6z - 15 = 6z - 11
2(3z -4) = 6z - 8
Here's the tricky part. You are only taking 8 away from 6z
The result is going to be larger than when you take away 11 from 6x
Try it
suppose z = 7
6*7 - 8 = 42 - 8 = 34
6*7 - 11 = 42 - 11 = 31

Write an equation of the line in slope intercept form that passes through (0,4) and (-3,-8)
Answer:
y=4x+4
Step-by-step explanation:
The equation for the slope-intercept form is y=mx+b. m is the slope and b is the y-intercept. To find the slipe we can use the equation m=y2-y1/x2-x1, next decide which one you want as x1,y1, and which one as x2,y2 (doesn't really matter which one you choose.) I then plugged in my value and got the equation -8-4/-3-0=m=4. so far we have y=4x+b. b is our y-intercept which they already have us, which is 4 so we just have to plug it in and get our answer y=4x+4.

Molly is making a quilt for her mother. The quilt will have several designs. One of the designs is shown below. What is the total perimeter of this design, in inches? A. B. C. D.
Answer: A. 12 + 12√12
Step-by-step explanation:
The perimeter of a triangle is acquired by adding up all the sides of the triangle.
In this case therefore the perimeter is;
= 2√2 + 2√2 + 4
= 4√4 + 4
There are 3 triangles so the total perimeter is;
= 3 * (4√4 + 4)
= 12√12 + 12
= 12 + 12√12
