What is the slope of the line containing the points (5,-8)
and (-5,8)?
Answer: m = -⁸⁄₅
PLz mark brsinliest:)
The slope of the line containing the points (5,-8) and (-5,8) is -8/5 after using the concept of the slope of a line.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
The line containing the points (5,-8) and (-5,8)
A straight line is a combination of endless points joined on both sides of the point.
As we know from the formula of the slope:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\rm m =\dfrac{8-(-8)}{-5-5}[/tex]
m = (8 + 8)/(-10)
m = -16/10
m = -8/5
Thus, the slope of the line containing the points (5,-8) and (-5,8) is -8/5 after using the concept of the slope of a line.

Answer:
y = 2
Step-by-step explanation:
Rearrange terms
3y -4 = -2y +6
Add 4 to both side
3y -4 +4 = -2y +6+4
Simplify
3y = -2y + 10
Add 2y to both sides
3y +2y = -2y + 10 +2y
Simplify
5y = 10
Divide both sides by the same factor
5y/5 = 10/5
Simplify

Luna went over to a friend's house to play. She arrived at her friend's house at 9:23 A.M. and went back home at 2:06 P.M. How long did Luna stay at her friend's house?
Step-by-step explanation:
AM switches to PM at 12 PM.
so, we need to calculate the time from 9:23 am to 12 pm, and then from 12 pm to 2:06 pm, and then add both for the overall answer.
the first full hour after 9:23 am is 10 am. from there it is 2 hours to 12 pm.
how many minutes from 23 minutes to 60 (of the next full hour) ? 60 - 23 = 37 minutes.
so, it is 2 hours and 37 minutes until 12 pm.
and from 12 pm to 2:06 pm it is 2 hours and 6 minutes.
the total time is then
2 hours 37 minutes + 2 hours 6 minutes =
= 2 + 2 hours 37 + 6 minutes = 4 hours 43 minutes
FYI
if the sum of the minutes would have been larger than 60 (like e.g. 53 + 12), then we would have had to add another hour as a carry over, and take the remainder of minutes/60 as minutes.
e.g.
2 hours 53 minutes
3 hours 12 minutes
would sum up to
5 hours 65 minutes = 6 hours 5 minutes
In this polygon, all angles are right angles What is the area of this polygon?
Answer:
428 square ft
Step-by-step explanation:
to do this you can break the shape up into multiple pieces
you can do it this way
the top left part of the polygon could be one shape
9 by 10
this is because if the left side is 23 and part of the left side is 13 the leftover part is 10
then the bottom is 13 by 26
then you multiply and add them together
(9 * 10) + (13 * 26) = 90 + 338
then you add
90 + 338 = 428
the answer is 428 square ft
A soccer ball is kicked upward from a height of 2 feet with an initial vertical velocity of 30 feet per second. The function: h(t)=-16t^2+30t+2h(t)=−16t 2+30t+2 represents this situation.
To the nearest hundredth of a second, when will the soccer ball hit the ground?
It would take about 1.94 seconds for the soccer ball to hit the ground.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of the soccer ball after time t, hence:
h(t) = -16t² + 30t + 2
The soccerball hits the ground when h = 0, hence:
0 = -16t² + 30t + 2
t = 1.94 seconds
It would take about 1.94 seconds for the soccer ball to hit the ground.

2. In square MISA, the diagonals intersect at point P. If m_MPA
= (2s + 3t)º, MZISP = (4r + s)° and m_MIS = (3s – 2t)º, find
the values of r, s, and t.
The diagonal of the square MISA bisect the angle at the vertices
The values of r, s and t are r = 2.6, s = 34.6 and t = 6.9
How to determine the values of r, s and t?The given parameters are:
MPA = (2s + 3t)º
ISP = (4r + s)°
MIS = (3s – 2t)º
The angle between the diagonal of a square is 90 degrees.
So, we have:
2s + 3t = 90
Multiply by 2
4s + 6t = 180
The angle at the vertices of the square is 90 degrees.
So, we have:
3s - 2t = 90
Multiply by 3
9s - 6t = 270
The diagonal bisect the angle at the vertex.
So, we have:
4r + s = 45
Rewrite the equations
4s + 6t = 180
9s - 6t = 270
4r + s = 45
Add the first and the second equations
4s + 9s + 6t - 6t = 180 + 270
13s= 450
Divide by 13
s = 34.6
Substitute s= 34.6 in 4r + s = 45 and 3s - 2t = 90
4r + 34.6 = 45
Solve for r
r = 2.6
3 * 34.6 - 2t = 90
Solve for t
t = 6.9
Hence, the values of r, s and t are r = 2.6, s = 34.6 and t = 6.9

This is correct because we already know that the two sides are congruent and that we have one more side we need to prove congruent. Well, it is congruent because it's just lined up next to each other, so they're equal which is BD=DB. This would make it so it would be SSS and the two triangles are congruent.

Given the sequence, 3, -9,27,-81 ...
What is the 15th term, assuming the pattern continues
Fist : 3
then
second : x (-3) = - 9
third : x (-3) = 27
x (-3) = - 81
the 15 term ?
first one = 3 x (-3)⁰
second one = 3 x (-3)¹
third one = 3 x (-3)²
so n one = 3 x (-3)ⁿ⁻¹
then the 15th one = 3 x (-3)¹⁴

Y+5.6=8.28
So what does y = to ?
Answer:
Y = 2.68
Step-by-step explanation:
Y + 5.6 = 8.28
To find Y, you would need to subtract 5.6 from both sides:
Y + 5.6 - 5.6 = 8.28 - 5.6
So that would simplify to:
Y = 8.28 - 5.6
8.28 - 5.6 = 2.68
So Y = 2.68
