Answer:
Step-by-step explanation:
Remark
They are alternate interior angles and therefore equal.
Solution
8x - 10 = 3x + 90 Subtract 3x from both sides
8x - 3x - 10 = 90 Combine the left
5x - 10 = 90 Add 10 to both sides
5x = 90 + 10
5x = 100 Divide by 5
x = 20
================
That isn't the answer. You need 3x + 90
<B = 3*20 + 90
<B = 60 + 90
<B = 150

Which ordered pair, when graphed, would not show a function?
(miles per gallon, gallons in tank)
(length of shadows/time of day)
(temperature in F, temperature in C)
(number of employees, number of hours worked)
Answer:
a) miles per gallon, gallons in tankStep-by-step explanation:
All the options show functional relationship but the first one
a) miles per gallon, gallons in tank
There is no direct relationship between these parameters as miles per gallon depends on the speed and the way of driving. This won't be a function when graphed.b) length of shadows/time of day
Shadow depends on the time of the day and its length wont repeat at different angles. This is a function.c) temperature in F, temperature in C
This is a function as each input will have a unique output.d) number of employees, number of hours worked
Hours of work depends on number of employees. This is a functional relationship.Answer:
(number of employees, number of hours worked)
Step-by-step explanation:
Tell whether each relationship is a function.

A cell phone company is interested in the relationship between the number of texts per minute for their customers (y) and customer age. Based on the collected data, the least squares
regression line is y3.27 2.14, where x is the number of years by which age exceeds 12. Which of the following statements best describes the meaning of the slope of the least squares
regression line (points)
of your the estimated number of tots per minute increases by 27
The question is incomplete. Here is the complete question.
A cell phone company is interested in the relationship between the number of texts per minute for their customers (y) and customer age. Based on the data collected, the least-squares regression line is [tex]y=3.27+2.14x[/tex], where x is the number of years by which age exceeds 12. Which of the following statements best describes the meaning of the slope of the least-squares regression line?
a. For each increase in age of 1 year, the estimated number of texts per minute increases by 3.27.
b. For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.
c. For each increase of one text per minute, there is an estimated increase in age of 3.27 years.
d. For each increase of one text per minute, there is an estimated increase in age of 2.14 years.
e. The slope has no meaning because the units of measure for x and y are not the same.
Answer: b. For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.
Step-by-step explanation: The least-squares regression is a method of fitness, i.e., it fits a data set of number into an equation.
In this case, the relationship between number of texts per minute and customer age is given by a line equation:
[tex]y=3.27+2.14x[/tex]
in which, y represents the number of texts per minute and x is the age.
In a line equation, slope is the measure of steepness, i.e., how inclined the line is.
In the least squares regression line, slope is 2.14 and it means, in each additional year, the number of texts increase by a factor of 2.14, which is the correct alternative.

(3a2 + 2ab + 2b) + (5a2 − 3ab + 9)
Step-by-step explanation:
[tex] \tt{(3 {a}^{2} + 2ab + 2b) + (5 {a}^{2} - 3ab + 9})[/tex]
~While adding , the sign of each term of second expression remains same. So, Remove the unnecessary parentheses :
⤑ [tex] \tt{3 {a}^{2} + 2ab + 2b + 5 {a}^{2} - 3ab + 9}[/tex]
~Like terms are those which have the same base. Combine the like terms :
⤑ [tex] \tt{3 {a}^{2} + 5 {a}^{2} + 2ab - 3ab + 2b + 9}[/tex]
⤑ [tex] \sf{8 {a}^{2} - ab + 2b + 9}[/tex]
[tex] \red{ \boxed{ \boxed{ \tt{ ⟿ Our \: final \: answer : 8 {a}^{2} - ab + 2b + 9}}}}[/tex]

Answer:
Simplified answer is: [tex]8a^2 - ab + 2b + 9[/tex]
Step-by-step explanation:
Key skills needed for understanding: Combining Like Terms
1) You are given the equation: [tex](3a^{2} + 2ab + 2b) + (5a^{2} - 3ab + 9)[/tex]
- Since you are adding here, you can remove the parentheses.
- If you remove them it would be --> [tex]3a^2 + 2ab + 2b + 5a^2 - 3ab + 9[/tex]
2) Now we have to combine like terms in order to simplify this equation.
Combining like terms is simply combining terms with the same base (such as the terms that have "ab" or the terms that have "[tex]a^2[/tex]" or the terms that have nothing - these terms are numbers such as 9 or 5).
You can combine 2ab and -3ab, but you cannot combine 9 and 2b. Hope you understood this concept.
3) If you combine like terms ( [tex]3a^2 + 5a^2[/tex], [tex]2ab - 3ab[/tex]) you will get a different expression: [tex]8a^2 - ab + 2b + 9[/tex].
[tex]8a^2 - ab + 2b + 9[/tex] is the answer.
Hope you understood and have a nice day!! :D

A puppy named Blue started out at 2 pounds and gained 4 pounds every month. How heavy
was Blue at 8 months old?
Answer:
34 pounds
Step-by-step explanation:
One month, Blue will be 6
Two month, Blue will be 10
Three month, Blue will be 14
Four month, Blue will be 18
Five month, Blue will be 22
Six month, Blue will be 26
Seven month, Blue will be 30
Eight month, Blue will be 34
By adding 4 every month, you will get 34
or
4 x 8 = 32
32 + 2 = 34
Sorry if my reasoning doesn't make sense-
Anyways, hopefully this helped! :D

Name the property shown.
(9 + 3) + 2 = 9+ (3 + 2)
Answer:
associative property
Step-by-step explanation:
The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Add some parenthesis any where you like

On a number line, the directed line segment from Q to S has endpoints Q at a -8 and S at 12 Point R partitions the direct line segment from Q to S in a 4:1 ratio Which expression correctly uses the formula (m/m+n)(x2 - x1) + x1 to find the location of point R?
Answer:
[tex]R =\frac{4}{4+1}(12 +8) -8[/tex]
Step-by-step explanation:
Given
[tex]QS = (-8,12)[/tex]
[tex]Ratio = 4 : 1[/tex]
Required
Determine the expression that correctly uses [tex]\frac{m}{m+n}(x_2 - x_1) + x_1[/tex]
In [tex]QS = (-8,12)[/tex]
[tex](x_1,x_2) = (-8,12)[/tex]
and
[tex]m:n = 4:1[/tex]
Substitute these values in:
[tex]\frac{m}{m+n}(x_2 - x_1) + x_1[/tex]
[tex]R =\frac{4}{4+1}(12 - (-8)) + (-8)[/tex]
The expression becomes:
[tex]R =\frac{4}{4+1}(12 +8) -8[/tex]
Solving further:
[tex]R = \frac{4}{5}(20)-8[/tex]
[tex]R = \frac{4*20}{5}-8[/tex]
[tex]R = \frac{80}{5}-8[/tex]
[tex]R = 16 - 8[/tex]
[tex]R = 8[/tex]
Hence, R is at 8 on the number line

Bag A contains 3 red balls and 3 blue balls.
Bag B contains 1 red ball and 3 blue balls.
A ball is taken at random from bag A and placed in bag
B. A ball is then chosen from bag B. What is the probability
that the ball taken from B is red?
Answer:
30% probability that the ball taken from B is red.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Red ball from urn A:
3/6 = 1/2 probability of getting a red ball from urn A.
Then urn B will have 5 balls, 2 of which are red, so 2/5 probability of getting a red ball.
Blue ball from urn A:
3/6 = 1/2 probability of getting a blue ball from urn A.
Then urn B will have 5 balls, 1 of which is red, so 1/5 probability of getting a red ball.
Total:
[tex]p = \frac{1}{2}*\frac{2}{5} + \frac{1}{2}*\frac{1}{5} = \frac{2}{10} + \frac{1}{10} = \frac{3}{10}[/tex]
3/10 = 0.3 = 30%.
30% probability that the ball taken from B is red.

51÷251=
Find the remainder
Answer:
0.20
Step-by-step explanation:
Answer/Step-by-step explanation:
How about we go bit by bit, attempt to decrease numerator to a number nearer to different of denominator which likewise ought to be measurable.
5^251/135*5^250/135*(25)^125/13Rem[5*(25)^125/13]Rem[5*(-1)^125/13]Rem[-5/13}Answer is 8
This is an exemplary illustration of Leftover portion Hypothesis, here on the off chance that you get befuddled as a result of negative remainder, at that point attempt to compose it in easier term this way,
-5 = 13*(-1) + 8 , here 8 is remainder. Remainder can also be 13+5 = 18 by writing like this,
-5 = 13*1 -18, but again dividing -18 by 13 will yield to value which we got earlier that’s 8.
Hope this helped!
