The question is incomplete as the matrix is not given.
The general form of a matrix is:
[tex]b[m*n] =\left[\begin{array}{ccc}b_{11}&b_{12}&b_{13}........b{1n}}\\b_{21}&b_{22}&b_{23}........b{2n}\\b_{31}&b_{32}&b_{33}........b{3n}\\ \\ \\b_{m1}&b_{m2}&b_{m3}........b{mn}\end{array}\right][/tex]
Where m and n represent the [tex]number\ of\ rows\ and\ columns[/tex] respectively.
Notice the position of b11
This means that b11 is at the first column and first row.
Take for instance matrix b is:
[tex]b = \left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]
The element at the first row and first column is 1.
Hence
[tex]b_{11} = 1[/tex]

It is given that p varies inversely as q. If p = 12 and q = 45 find p, if q is 135.
Answer:
[tex]p =4[/tex]
Step-by-step explanation:
Given
Variation: Inversely
[tex]p = 12[/tex] when [tex]q = 45[/tex]
Required
Determine p when [tex]q = 135[/tex]
First, we need to determine the relationship between p and q
Since, it is an inverse variation.
The relationship is:
[tex]p\ \alpha\ \frac{1}{q}[/tex]
Convert to an equation
[tex]p= k *\frac{1}{q}[/tex]
[tex]p= \frac{k}{q}[/tex]
Where k = constant of variation
Make k the subject
[tex]k = p * q[/tex]
When [tex]p = 12[/tex] and [tex]q = 45[/tex]
[tex]k = 12 * 45[/tex]
[tex]k = 540[/tex]
To solve for p when q = 135
Substitute 135 for q and 540 for k in [tex]p= \frac{k}{q}[/tex]
[tex]p = \frac{540}{135}[/tex]
[tex]p =4[/tex]
If two angles are supplementary, then they are not congruent. Which diagram provides a counterexample for the statement?
A) A
B) B
C) C
D) D
Answer:
a
Step-by-step explanation:
supplmentay angles are either of two angles whose sum is 180°
option b is two right angles (90 degree on both) add them together you get 180.
option c is 60 degrees and 120 degrees add them together to get 180 degrees.
option d is 155 degrees and add 25 degrees you get 180.
so the answer is a, because 30 degrees and add the other 30 degrees together you only get 60
The correct answer is A, because 30 degrees and add the other 30 degrees together you only get 60.
What are supplementary angles?The supplementary angles are defined as the angles whose sum is equal to 180°.
Supplementary angles are either of two angles whose sum is 180°
Option b is two right angles (90 degrees on both) add them together you get 180.
Option c is 60 degrees and 120 degrees add them together to get 180 degrees.
Option d is 155 degrees and add 25 degrees you get 180.
Therefore, the answer is A, because 30 degrees and adding the other 30 degrees together you only get 60.

6. A rental car agency charges $240 per week plus $0.25 per mile to rent
a car. The charge for a minivan is $180 per week plus $0.40 per mile.
After how many miles is the total charge for each vehicle the same?
Answer:
400 Miles
Step-by-step explanation:
Set up the equations and make them equal to each other and then solve.
240+0.25m=180+0.40m
Answer
400 miles
Step-by-step explanation:
After 400 miles, both will be costing the same, you first create an equation with the values you have, for example, 240 + .25x and you either graph them and find the intersection or guess and check.
Based on the housing data below, use linear regression to estimate a fair price for a 1900 ft2 home. Square Feet House Price (in thousands) 1400 1700 105 135 1500 183 O A. $140,000 B. $156,000 C. $160,000 D.- $176,000
The solution is Option D.
The fair price of a 1900 ft² home is given by the equation A = $ 176,000
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the square feet of the house be represented as x
Let the number of houses be represented as y
Let the first point be P ( 1400 , 105)
Let the second point be Q ( 1500 , 183 )
Now , the slope of the equation is given by
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope m = ( 183 - 105 ) / 1500 - 1400
Slope m = 78 / 100
Slope m = 0.78
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 1400 = 0.78 ( x - 105 )
On simplifying the equation , we get
y - 1400 = 0.78x - 81.9
Adding 1400 on both sides of the equation , we get
y = 0.78x + 1318.1
Therefore , the value of y is 0.78x + 1318.1
Hence , the equation of line is 0.78x + 1318.1 and the price is $ 176,000

180-102=78
Answer:
Step-by-step explanation:
first find the final interior angle since we need it to find the exterior
60 + 42 = 102
180 - 102 = 78 degrees
then we just have to do 180 - 78 bc we have a straight line and straight lines are always 180 degrees
180 - 78 = 102 degrees
x = 102

Andre and Alina are each saving money. Andre starts with $100 in a savings account and adds five dollars per week Elena starts with $10 in her savings account and add $20 each week after how many weeks for Andre and Elena have the same amount of money in their savings account
Answer:
6 weeks
Step-by-step explanation:
From the question:
Let us represent the number of weeks as x
Andre and Alina are each saving money.
For Andre:
Andre starts with $100 in a savings account and adds five dollars per week
$100 + $5 × x
= 100 + 5x
For Elena
Elena starts with $10 in her savings account and add $20 each week
$10 + $20 ×x
= 10 + 20x
The next step is to equate both algebraic expression for Andre and Elena together
Hence:
100 + 5x = 10 + 20x
Collect like terms
100 - 10 = 20x - 5x
90 = 15x
x = 90/15
x = 6 weeks
Hence, after 6 weeks Andre and Elena would have the same amount of money in their savings account.

Marco has a $15.00 gift card to a movie theater. He wants to buy each of his friends a $3
candy bar. The function f(x)=3x-15 represents the amount of cash needed to purchase x candy
bars after using his gift card. He brings 7 friends. How much of his own money does he need
to spend to buy all 7 friends a candy bar?
Answer:
I believe the answer is 6
Step-by-step explanation:
f(x) = 3x - 15 -- plug 7 into x (that's how many candy bars he's buying)
f(x) = 3(7) - 15 -- solve the equation (just know that 3(7) is the total, and 15 is the amount of money on his gift card.)
f(x) = 21 - 15
f(x) = 6 -- your answer
