For each value of y, determine whether it is a solution to 12 = 2y +8.
Is it a solution
Answer: 2(0) + 8 does not equal 12, not a solution.
2(2) +8 = 12 yes it is a solution
2(-3) + 8 does not equal 12, not a solution
2(5) + 8 does not equal 12, not a solution.
Step-by-step explanation:
Looks like you need to plug in each y value given and multiplied by 2 and add 8
2(0) + 8 does not equal 12, not a solution.
2(2) +8 = 12 yes it is a solution
2(-3) + 8 does not equal 12, not a solution
2(5) + 8 does not equal 12, not a solution.

Measures of location - Mean, median, and mode
Consider the following set of sample data.
20 25 25 36 42 56 6974 98 100
For the given data, the mean is______ , the median is_______ , and the mode is_______ Suppose the value 98 in the data is mistakenly recorded as 78 instead of 98. For the sample with this error, the mean______ is the median is________ , and the mode is_______ . The mean the median________ , and the mode_______ Suppose the value 98 in the original sample is inadvertently removed from the sample. For the sample with this value removed, the mean is ______, the median is_______ , and the mode is_________ .
Step-by-step explanation:
1.
20+25+25+36+42+56+69+74+98+100 = 545
n = 10
Mean = 545/10
= 54.5
Median = 42+56/2 = 98/2 = 49
Mode = 25 since it occurred twice
2.
If 98 is recorded as 78
20+25+25+36+42+56+69+74+78+100
= 525
Mean = 525/10 = 52.5
Median = 42+56/2 = 98/2 = 49
Mode = 25
3.
If 98 is removed
20+25+25+36+42+56+69+74+ 100= 447
n = 9
Mean = 447/9 = 49.6
Median = 42
Mode = 25

Answer:
The answer is - 2Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3, −7) and (−1, 1)
The slope is

What is wrong and how do we do it to find the answer.
(Explain and add and multiply)
Answer:
60 x 60 = 3600
Step-by-step explanation:
First if we wanted to, this is optionial, we can simplify this; 6 x 6 = 60 x 60
So 6x6 = 36, so for 60 x 60 we would add 2 0´s to the answer since we have 2 zeros added up in 60 and 60. so 60 x 60 = 3600

An electronics store offers to finance the purchase of any single item with zero interest for one year, with a down payment of $60. The rest of the purchase price will be split evenly into four quarterly payments. Which of the following equations represents the relationship between the amount, a dollars, of each quarterly payment and the purchase price, s dollars, of an item under this offer? with step by step explanation
Answer:
4x+60=s
Step-by-step explanation:
x is the constant amount that mus be payed and since it will be payed 4 times you multiply x by 4
and 60 is just added to the quarterly paments that will be payed
annd all of that must equal the price of the item s

Rachel took clothes to the cleaners three times last month. First, she brought 3 shirts and 1 pair of slacks and paid $11.46. Then she brought 5 shirts, 2 pairs of slacks,
and 1 sports coat and paid $27.92. Finally, she brought 5 shirts and 1 sports coat and paid $19.94. How much was she charged for each shirt, each pair of slacks, and
each sports coat?
Rachel was charged for each shirt, $ for each pair of slacks, and $ for each sports coat.
Matrixes
Answer:
$2.49 each shirt$3.99 each slacks$7.49 each sports coatStep-by-step explanation:
If we let s, p, c represent the cost of cleaning the shirts, pants, and coats, respectively, the problem information lets us write three equations:
3s +1p +0c = 11.46
5s +2p +1c = 27.92
5s +0p +1c = 19.94
__
A variety of methods and tools are available for solving these equations. We can do it "by hand" using elimination and substitution.
Subtracting the 3rd equation from the 2nd, we get ...
(5s +2p +c) -(5s +c) = (27.92) -(19.94)
2p = 7.98
p = 7.98/2 = 3.99
Substituting this value into the first equation gives ...
3s +1(3.99) = 11.46
3s = 7.47 . . . . . . . . . . subtract 3.99
s = 7.47/3 = 2.49
Substituting this value into the last equation gives ...
5(2.49) +c = 19.94
c = 7.49 . . . . . . . . . . . subtract 12.45
Rachel was charged ...
$2.49 for each shirt
$3.99 for each pair of slacks
$7.49 for each sports coat

find the value of x.
Answer:
x=8
Step-by-step explanation:
Set 40 + y = 90
y=50
y = 6x + 2
6x + 2 = 50
6x = 48
48/6 = x
x=8
Answer:
8
Step-by-step explanation:
(6x + 2) + 40 = 90 because the entire angle is a right angle, therefore the whole angle is 90
subtract 40 from each side: 6x + 2 = 50
now subtract 2 from each side: 6x = 48
now divide 6 from each side: x = 8

Find three consecutive numbers whose sum is 84
Answer:
27,28,and29
Step-by-step explanation:
27+28+29=84
For example:
x+(x+1)+(x+2)=84
3x+3=84
3x=81
x=27
Now since x=27,replace the x
21+1=28
28+1=29
27+28+29=84
Hopes this helps :)
The three consecutive numbers whose sum is 84 is 27, 28 and 29.
Given the question to find three consecutive numbers whose sum is 84.
Consecutive numbers are numbers which lies next to each other in the set of counting numbers.
Let x be the starting number in the set of counting numbers.
Then the next consecutive number to it is x + 1.
And the next consecutive number to this is x + 2.
So we have,
x + x + 1 + x + 2 = 84
Adding like terms,
3x + 3 = 84
Subtracting 3 from both sides,
3x = 81
Dividing by 3 on both sides,
x = 27
So, x + 1 = 27 + 1 = 28
x + 2 = 27 + 2 = 29
Hence the numbers are 27, 28 and 29.

Find a linear equation whose graph is a straight line with the given properties through (0.5,6) and parallel to the line 4x-2y=15
Answer:
y = 2x + 5 or -2x + y = 5Step-by-step explanation:
Given line:
4x - 2y = 15Converted to slope-intercept form of y= mx + b
2y = 4x - 15y = 2x - 7.5Parallel lines have a same slope, so the line will be:
y = 2x + bUsing the point given (0.5, 6), finding the value of b:
y = 2x + b6 = 2*0.5 + bb = 6 - 1b = 5So the line is:
y = 2x + 5or
-2x + y = 5
For each value of w, determine whether it is a solution to 6w +9=33.
Is it a solution?
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
3 (no)
9 (no)
-7 (no)
-1 (no)
The solution to the equation 6w + 9 = 33 is 4.
The values of 2 = 3, 9, -7, and -1 are not solutions to 6w + 9 = 33.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
6w + 9 = 33
6w = 24
w = 4
For w = 3
6 x 3 + 9 = 33
18 + 9 = 33
27 = 33
This is not true so it is not a solution.
For w = 9
6 x 9 + 9 = 33
54 + 9 = 33
63 = 33
This is not true so it is not a solution.
For = - 7
6 x (-7) + 9 = 33
-42 + 9 = 33
-33 = 33
This is not true so it is not a solution.
For w = -1
6 + (-1) + 9 = 33
-6 + 9 = 33
3 = 33
This is not true so it is not a solution.
Thus,
None of the values of w are solutions to 6w + 9 = 33.
