Answer:
m=-1/2
Step-by-step explanation:
f(6)=-2 is (6,-2) and f(-4)=3 is (-4,3)
the equation for slope (m) is (y2-y1)/(x2-x1)
label the points:
x1=6
y2=-2
x2=-4
y2=3
now substitute into the equation:
m=(3--2)/(-4-6)
m=5/-10
m=-1/2
the slope is -1/2
hope this helps!
cmon and help dis is my last question
What question I don't see anything?
Find the values of x and y.
help please work has to be shown ..
Answer:
x = 7 and y = 17
Step-by-step explanation:
16x + 9x + 5 = 180 cuz they are supplementary
25x = 175
x = 7
We also know that 16x + 4y = 180
so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17
hope this makes sense
What is the value of x?
pls help ;-;
Answer:
39 degrees
Step-by-step explanation:
A triangle sums up at 180 degrees.
Therefore, 102+39=141.
Subtract 180 by 141 and you get 39!
To know if your answer is correct, add all angles and
make sure to get 180 in total!

Answer:
x=10
Step-by-step explanation:
6^2+8^2=x^2
36+64=x^2
100=x^2
x=10
Answer:
10
Step-by-step explanation:
The pythagorean theorem states that a^2+b^2=c^2. a and b are the shorter sides and c is the hypotenuse, or the longest side. You can tell the hypotenuse because it is opposite to the right angle.
Therefore, a=6, b=8 and c=x. You can switch a and b if you like, it doesn't really matter.
using the pythagorean thm. 6^2+8^2=x^2. You simplify the exponents and combine like terms to get x^2=100. You take the square root of both sides and get 10.

Answer:
153.9
Step-by-step explanation:
the circumference is equal to the radius times 2 times pi or 3.14
the radius is equal to half the diameter.
39/2=24.5
24.5x2x3.14=153.86 but it tells us to round to the nearest tenth and when rounded it equals 153.9

38% = 0.38 in decimal form. Percent means 'per 100'. So, 38% means 38 per 100 or simply 38/100. If you divide 38 by 100, you'll get 0.38 (a decimal number).

If 420 = 120%, what would 100% equal?
Answer:
350
Step-by-step explanation:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
120% = 120/100 = 120 ÷ 100 = 1.2
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 120% of what number = 420?
120% × ? = 420
? =
420 ÷ 120% =
420 ÷ (120 ÷ 100) =
(100 × 420) ÷ 120 =
42,000 ÷ 120 =
350
ProofHow do we check the result?If 120% × 350 = 420 =>
Divide 420 by 350...
... And see if we get as a result: 120%
Note:Multiply a number by the fraction 100/100,
... and its value doesn't change.
100/100 = 100 ÷ 100 = 1
n/100 = n%, any number.
Hope it is helpful....so ive been noticing a lot of posts on this platform lately that are asking people to do entire essays or worksheets for 10 points? nobody will do that for you, and whenever someone actually does, stop saying 'can you elaborate on that'. it will just fail you later in life when you realize that you cant just keep using others to do ALL of your work. I understand what this app is for, but ask questions that you are REALLY confused on or that are REALLY too hard for you. either stop digging off of other people because it will hurt you only, or actually try to make an attempt at doing your work and then asking people to help you out on questions that you actually need help on, not ones that you are capable of but too lazy to do.

Factor completely: 5x^2-11x+6
Find the slope of the line shown on the graph to the right (-4,-3) and (2,3)
Answer:
y=x+1
Step-by-step explanation:
to do this we have to use the slope formula, Rise/Run which is (y2-y1)/(x2-x1) so (3-(-3) or 3+3 divided by (2-(-4) or 2+4, so the slope would be 6/6 or 1. so it is up one over one, and since at the x coordinate of 0 it is y=1 we know the formula must be y=x+1
Answer:
m = 1
Step-by-step explanation:
Use the equation [tex]m=\frac{y2-y1}{x2-x1}[/tex] to find the slope.
next, the equation should look like: [tex]y=\frac{3+3}{2+4}[/tex]
Next you should get the equation: [tex]m = \frac{6}{6}[/tex]
Finally, just divide 6/6 and the answer will be m = 1

Answer:
x = 2
Step-by-step explanation:
You can make a ratio out of this!
2 / x = (x+1) / 3
1. Cross multiply^
2. 2 * 3 = x (x+1)
3. 6 = x^2 + x
3. x^2 + x - 6
4. Factor^
5. (x-2)(x+3)
6. x - 2 = 0 turns into x = 2
7. x + 3 = 0 turns into x = -3
8. There's not way to measure -3 yet, so you are left with x = 2
Three shipping companies want to compare the mean numbers of deliveries their drivers complete in a day.
The first two shipping companies provided their data from a sample of drivers in a table.
Company C showed its data in a dot plot.
Answer the questions to compare the mean number of deliveries for the three companies.
1. How many drivers did company C use in its sample?
Write your answer in the space below.
2. What is the MAD for company C's data? Show your work.
Write your answer in the space below.
3. Which company had the greatest mean number of deliveries?
Write your answer in the space below.
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Write your answer in the space below.
Answer:
Step-by-step explanation:
1. the company C used 10 drivers
2. 6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10
(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)
4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4 = 16/10 = 1 6/10
3. The groups that had the most deliveries where group A and B
4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4
By reading the dot plot,
Number of drivers used by company C in its sample = 10
Mean absolute deviation for company C's data = 2
Company B has the greatest mean number of deliveries.
The mean deliveries of company B is 4 times MAD of company A.
What is dot plot?Dot plot is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis.
Number of units used in the sample of a dot plot can be calculated by simple counting.
What is mean absolute deviation?The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.
We are given the sum of each point from the mean. It is 20. Mean absolute deviation can be calculated by dividing this sum by number of observations.
Mean absolute deviation of company C = 20/10 = 2.
Mean A = 6
Mean B = 14
Mean B - Mean A = 8 = 4 * 2 = 4 times MAD (since MAD =2 for both companies).

Answer:
A.) 555 in.^2
Step-by-step explanation:
When solving these types of things, I usually like to cut it up into smaller, easier to manage shapes.
You can cut that trapezoid into two triangles and one rectangle.Since both triangles are the same size, you don't need to divide the base and height by two, so you'll get the area of both triangles combined (which saves some work). We know the length of the rectangle and bases of the triangle combined is 44 inches, and that the length of just the rectangle is 30 inches, so we can just subtract 30 from 44 and divide it by two for the base of a triangle.44 - 30 = 14
14/2 = 7
Now that we filled in the information not listed, we can finally solve:
The base of one triangle is 7 inches, and the height is 15 inches.
Now, we just multiple and divide it by 2 for one triangle (it would be 52.5 inches).
But, we don't need to divide it by two because both triangles are the same size, so we can just get the sum of the area of both triangles combined by skipping that step (because triangles are half a square and two of those triangles make a full square).
7 x 15 = 105
The area of both triangles combined: 105 in.^2
Next, we need to solve the area of the rectangle. This is easy considering all you have to do is multiply 15 by 30 (length times width).
15 x 30 = 450
The area of the rectangle: 450 in.^2
Now, the final step. Addition. All you need to do is add up all the sums, and you're done.
450 + 105 = 555
The area of entire figure: 555 in.^2
NOTE: the symbol '^' represents exponents, so when you see 555 in.^2, it means inches squared (or to the power of 2)
