The midpoint of \overline{\text{AB}} AB is M(5, 1)M(5,1). If the coordinates of AA are (3, 6)(3,6), what are the coordinates of BB?
Answer:
(7, -4)
Step-by-step explanation:
The formula for calculating midpoint is expressed as;
M(X, Y) = (x2+x1)/2, (y1+y2)/2
X = x1+x2/2
Y = y1+y2/2
Given
X = 5, Y = 1, x1 = 3, y1 = 6
Get x2
X = x1+x2/2
5 = 3+x2/2
10 = 3+x2
x2 = 10-3
x2 = 7
Get y2;
Y = y1+y2/2
1 = 6+y2/2
2 = 6+y2
y2 = 2-6
y2 = -4
Hence the coordinate of B is at (7, -4)

Adrian invested $790 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $2,550?
Answer:17
Step-by-step explanation:
trust me its right, no cap
As per compound interest, it would take 17 years for the value of the account to reach $2,550
What is the compound interest?If the invested amount is 'P', the rate of interest is r%, and the time of investment is 'n' years, then the compound interest after mentioned duration is = P[1 - [tex]e^{rn}[/tex]]
Given, the invested amount (P) = $790.
Rate of interest (r) = 6.9% = 0.069.
Let, the amount is invested for 'n' years.
The value of the amount after 'n' years = $2550.
Now, as per compound interest:
A = P. [tex]e^{rn}[/tex]
⇒ 2550 = 790 [tex]e^{(0.069n)}[/tex]
⇒ [tex]e^{(0.069n)}[/tex] = (2550 ÷ 790)
⇒ [tex]e^{(0.069n)}[/tex] = 3.23
⇒ 0.069n = 1.172
⇒ n = 17

Which is the correct equation for a line that has a slope of 2 and passes through the point (-1, -5). Use the graph below or graph paper if needed.
PLEASE HELP ASAP
A.y = 2x - 5
B.y = 2x + 5
C.y = 2x - 3
D.y = 2x + 3
9514 1404 393
Answer:
C. y = 2x - 3
Step-by-step explanation:
The y-intercept (b) can be found from ...
y = mx + b
y - mx = b . . . . . subtract mx
Here, you are given (x, y) = (-1, -5) and slope m = 2.
b = -5 -2(-1) = -5+2 = -3
The correct equation is ...
y = 2x -3 . . . . . matches choice C
_____
On the graph, you can plot point (-1, -5) left of the y-axis 1 unit and down from the x-axis 5 units. The slope of 2 tells you the line will rise 2 units from there to a y-value of -3 when it runs 1 unit to the right to an x-value of 0. That point (0, -3) is the y-intercept, showing you that choice C is correct.

please help me will give you brainliest!!
Answer:
yes, no, no, yes
Step-by-step explanation:
Plug in each point into both equations to see which ones fit.
For the first point, (4,1) it works for both equations.
1=-2( 4 ) + 9, 1= -8 + 9, 1=1
4( 4 )+2( 1 )=18, 16 + 2 = 18, 18 = 18
Do it for the rest of the points and plug them in and you get,
no for (5,-3) because -1 does not equal to -3
no for (6,0) because -3 does not equal to 0
(-5,19) is yes because 19=19 and 18=18

Another marble is taken at random.
What is the probability of getting exactly 1 red?
Answer:
im not sure but this is just a guess (please keep it in mind)
Step-by-step explanation:
4+5= 9 marbles all together
9-1= 8
1 in 8? or 1 in 9
this is becuase we dont know if the one that was taken out randomly first wasnt a red or not but then i could be wrong and the fact if it was red or blue in the first place might not even matter. it really depends.
