What is the equation of the line that passes through (5,-2) and (-3,4)
Answer:
y = -3/4x + 7/4
Step-by-step explanation:
y2 - y1 / x2 - x1
4 - (-2) / -3 - 5
6 / -8
= -3/4
y = -3/4x + b
4 = -3/4(-3) + b
4 = 9/4 + b
7/4

Answer:
a) - 10
Step-by-step explanation:
The two angles are vertical angles:
Angles that have a common vertex and whose sides are formed by the same lines.
Therefore, set your formula up as following
x+5=2x-5
x + 5 - 2x = -5
-x + 5 = -5
-x = -10

Find the length of the hypotenuse
Answer: The answer is “10cm”
Step-by-step explanation: To get to this answer we first need to know the formula for find the hypotenuse which is a^2 + b^2 = c^2. A and B are the two sides in this case a and b are 8 cm and 6 cm. Then you plug in the values into the equation, it looks like this 8^2 + 6^ = c^2 once you solve you get 64 + 36 = c. When you add 64 and 36 you get 100 but their is one more step. You must find the square root of 100 which is 10. So your answer for the hypotenuse is “10cm”
Have a nice day!
HELPPPPP ANSWER GETS BRAINLIEST
Answer:
56 degrees
Step-by-step explanation:
If you look at the m<KLN you can see that it is an acute angle. So, with this being said you have to know that the measure KLN is going to be less than 90 degrees. So you would subtract 180 and 124 and you would get 56 degrees.
I hope this helps :)

A stack of 500 pieces of paper is 1.875 inches tall. Compute the thickness of each piece of paper. Show your reasoning.
Answer:
0.003750 inches
If the thickness of 500 pieces is given as 1.875. the thickness of one sheet of paper can be determined by dividing the total inches by 500
Thickness of each paper = thickness of total paper / 500
1.875 / 500 = 0.003750 inches
Step-by-step explanation:
Answer:
If the thickness of 500 pieces is given as 1.875. the thickness of one sheet of paper can be determined by dividing the total inches by 500

Q2)You are trying to save $1500. You begin with $5 and save $3 more than the previous amount each week for 30 weeks. Will you meet your goal? Explain. Show work
Solution :
First term, a₀ = -10 .
Common difference of A.P. , d = -8 - (-10) = 2 .
Last term, aₙ = 24 .
We know, last term is given by :
aₙ = a₀ + (n-1)d
24 = -10 + (n-1)×2
2n - 2 = 34
n = 18
Now, sum of series is given by :
[tex]S_n = \dfrac{n}{2} \times ( 2a+(n-1)d)\\\\S_n = \dfrac{18}{2} \times ( 2\times -10 + ( 18 -1) \times 2)\\\\S_n = 126[/tex]
Hence, this is the required solution.

Part A: Factor 3x2a2 − 5xa2 − 2a2. Show your work. (4 points)
Part B: Factor x2 − 10x + 25. Show your work. (3 points)
Part C: Factor x2 − 81. Show your work. (3 points)
Answer:
Answer is in bold.
Step-by-step explanation:
Factor 3x2a2 − 5xa2 − 2a2.
3x2a2 − 5xa2 − 2a2=
a2(3x2 − 5x − 2)=
a2((x-2)*(x+(1/3)))
Part B: Factor x2 − 10x + 25.
x2 − 10x + 25.= (x-5)*(x-5)
Part C: Factor x2 − 81.
x2 − 81=(x-9)*(x+9)
