Given the square ABCD with points A(5, 10) and B(-4, 3), the slope of the line segment BC is 7/9
The formula for calculating the slope of a line is expressed as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Given the coordinate point A(5, 10) and B(-4, 3)
Substituting the given coordinate into the formula for slope
[tex]m=\frac{3-10}{-4-5}\\m=\frac{-7}{-9}\\m=\frac{7}{9}[/tex]
Hence the slope of the line segment BC is 7/9

Elli left home at 8:30 and returned at 12:15. How long was she away from home
Answer:
3 hours 45 minutes
Step-by-step explanation:
write the function in standard form y=-(x+3)(x+7)
To write this in standard form we need to multiply the two terms in parenthesis on the right side of the equation.
To multiply these two terms you multiply each individual term in the left parenthesis by each individual term in the right parenthesis.
y

Help pls I’m confused with this question ;/ and I will give brainliest :3
Answer:
I'm guessing frequency means deposits,
a. 13
b. $50
c. not sure what this means (sorry!)
d. $2,535
Step-by-step explanation:
Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day!
Part A
Answer: 13-------------
Explanation:
Add up all the values in the frequency column. This is because everything in the table represents a deposit of some kind.
3+1+5+2+2 = 13
========================================================
Part B
Answer: $50-------------
Explanation:
Simply list the value that has the highest frequency. This is the mode. It's possible to have more than one mode, and it's also possible to not have any mode at all.
========================================================
Part C
Answer: Median-------------
Explanation:
Let's list out all of the deposits. The repeats aren't typos. The deposits are
125, 125, 125, 300, 50, 50, 50, 50, 50, 205, 205, 100, 100
They sort to
50, 50, 50, 50, 50, 100, 100, 125, 125, 125, 205, 205, 300
Since we have n = 13 items here, the halfway point is n/2 = 13/2 = 6.5 which rounds to 7. The median is in slot 7. We have 6 items below the median and 6 items above the median (giving 6+1+6 = 13 total).
The value in slot 7 is 100, which shows us that 100 is the median.
========================================================
Part D
Answer: $2535-------------
Explanation:
Form a third column of values where we multiply each deposit by the corresponding frequency. Check out the table below.
After this third column is formed, add up those values to get the total amount of deposits. Spreadsheet software can make quick work of something like this. I used OpenOffice spreadsheet which is free software.
You should find that 1535 is the total amount deposited. This value is then added onto the $1000 already in there to get 1000+1535 = 2535

Dilate the figure by a scale factor of 2.5. Then, mark the statements as true or false.
After dilate the figure by a scale factor of 2.5, the orientation of the figure is not change.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The figure is dilated by a a scale factor of 2.5.
Now, We know that;
After dilation we get the pre image of the image which orientation of the figure is not change and both are similar to each other.
Thus, After dilate the figure by a scale factor of 2.5, the orientation of the figure is not change.

a submarine is located 358 feet below sea level. it ascends 169 feet. At what depth is the submarine now
Answer:
189
Step-by-step explanation:
Ascending means to go upwards. So, since it is below the surface heading upwards, you would subtract the amount of feet that it went up by from the depth it was previously at.
358, take away 169, is 189.

Determine whether the pair of lines is parallel, perpendicular, or neither.
x−4y=−9
y=3x−7
Choose the correct answer below.
A.
More information is needed.
B.
The two lines are perpendicular.
C.
The two lines are neither parallel nor perpendicular.
D.
The two lines are parallel.
Answer:
C
Step-by-step explanation:
you want to get y by itself and they would have the same slope if they were parallel. The Slope is not the same. to be perpendicular the sign would need to be changed 1/4 and 3 are not opposites. So it would make it C

Mr James gives £500 to his children Ally,
Barry and Cat in the ratio 2:3:5.
How much do they each receive?
Answers:
Ally gets 100 poundsBarry gets 150 poundsCat gets 250 pounds=====================================================
Work Shown:
x = some positive real number
2x = amount Ally gets
3x = amount Barry gets
5x = amount Cat gets
Note that the ratio 2x:3x:5x reduces to 2:3:5 after dividing all parts by x.
Add up the parts and you should get a sum of 500 pounds. Solve for x.
2x+3x+5x = 500
10x = 500
x = 500/10
x = 50
Based on that x value, we then can say:
2x = 2*50 = 100 pounds is what Ally gets3x = 3*50 = 150 pounds is what Barry gets5x = 5*50 = 250 pounds is what Cat getsAs a check, 100+150+250 = 500.
Also, note that the ratio 100:150:250 fully reduces to 2:3:5 after dividing all parts by the GCF 50.
Those two facts help confirm our answers.

distrubute the - sign on the bracket number
3x+12-2x-7
combine the like terms
3x-2x= 1x which is just x
12-7=5
x=5
Answer:
x+5
