Answer:
-3
Step-by-step explanation:
6 + (six more) 3x (3 times a number) = x (is equal to the number)
6 + 3x = x
6 + 2x = 0
2x = -6
x = -3

20. Determine whether the given points are on the graph of y = 3x + 2.
Select all points that lie on the graph.
(2,0)
(2,8)
(3,9)
(5,17)
Answer:
The points that were given are not on the graph of y=3x+2.
Step-by-step explanation:
The slope is 3 and the y-intercept is 2 so on the graph you rise three times from the point (0,0) to (0,3) then you run twice to the right so your first plot would be (2,3). After following the same process the next three plots would be (4,6),(6,9),&(8,12). So those plots that were given are incorrect. Remember y=mx+b
Mx is your slope to rise with and b is your y-intercept to run with.
Rise/run. I just put the important stuff in bold.

For the two numbers listed, find two factors of the first number such that their product is the first number and their sum is the second number.
- 10,9
9514 1404 393
Answer:
10, -1
Step-by-step explanation:
If you assume the numbers are integers, you can look at the factor pairs that make -10:
-10 = 10(-1) = 5(-2) = 2(-5) = 1(-10)
The sums of these pairs are 9, 3, -3, -9, so the pair of interest is the first one:
10, -1
A shop in the mall is 6 yards by 11 yards. How much would it cost to recarpet the shop with carpet that costs $5.00 per square yard?
Answer:
$330
Step-by-step explanation:
To find the total area of the shop do 6 times 11
6*11 = 66 sq. yards
Now, do 5 * 66 because one yard is $5
5 * 66 = 330
It costs $330

if SP is equal to rupees 400 and loss percent is 20% find CP
100-20=80%=400
[tex]\\ \rm\longmapsto 80\%\:of\:CP=400[/tex]
[tex]\\ \rm\longmapsto CP=400\times \dfrac{100}{80}[/tex]
[tex]\\ \rm\longmapsto CP=5(100)[/tex]
[tex]\\ \rm\longmapsto CP=500[/tex]
Step-by-step explanation:
Given,
S.p.=Rs400
Loss percent(L%) =20%
C.p.=?
We know,
S.p. =(100-L) % of c.p.
or,400=(100-20)% *c.p.
or,400=80% *c.p.
or, 400=80/100*c.p.
or,c.p.=Rs.500
Here, c.p.=Rs.500

if the cost price of 10 tables is equal to the selling price of 16 tables , find out the gain or loss percentage
Hi,
To solve this problem, Let us take the LCM of 10 and 16 which will come 80.
Now suppose the cost price of 10 tables =₹n CP of 80 tables will be ₹ 8n
According to the question, CP of 10 tables is equal to the SP of 16 tables, then
the SP of 16 tables will also be ₹ n.
So, SP of 80 tables will be ₹ 5n
So, Loss = CP-SP
→ 8n - 5n = ₹ 3n
Loss%= (3n×100)/8n
Loss%= 37.5%.
Hence the correct answer will be a loss of 37.5%.
this isn’t a question but to everyone who’s actually good at math thank you so much for taking the time to answer these questions.

linear equation 4x-1=9
Answer:
5/2 or 2.5
Step-by-step explanation:
4x-1=9
4x=9+1
4x=10
x=10/4
x=5/2 or 2.5
Answer:
x = 5/2
Step-by-step explanation:
4x - 1 = 9
4x - 1 + 1 = 9 + 1
4x = 10
4x/4 = 10/4
x= 5/2

According to the 1.5.IQR rule for outliers, how many high outliers are there in the data set?
Choose 1 answer:
Taking into account the rule 1.5 IQR, there aren't high outliers in the displayed data set.
Calculation of the Interquartile Range and the rule 1.5 IQR.
To calculate the Interquartile Range IQR, you must subtract the value of the first quartile Q1, to the third quartile Q3, as you can see in the formula below:
IQR = Q3 - Q1Using the five-number summary, you can replace the formula:
IQR = 17 - 13IQR = 4Before to apply the rule 1.5 IQR, you must multiply the IQR by 1.5:
4 * 1.5 = 6Now, to apply the rule you must add the value obtained (6), to the third quartile (17), if any data is over this, theoretically it's an outlier:
17 + 6 = 23 (As you do not have any data over this value, it is identified that there are no outliers in the upper section).Finally, you must subtract the value obtained (6) to the first quartile (13), if any data is under this, theoretically it's an outlier:
13 - 6 = 7 (Since you don't have any castle data built before this century, there wouldn't be any theoretically outliers either).By this reason, using the rule of 1.5 IQR, you can see there aren't outliers in the displayed data set.

solve for x of the given angle
Answer:
m<ABC = 92
Step-by-step explanation:
(3x + 23) and 4x are equal angle wise. So we have the equation:
(3x + 23) = 4x
3x = 4x - 23
-x = -23
x = 23
Multiply x by 4 which is 92
