Answer:
The coordinates of point B are (23,-2)
Step-by-step explanation:
Mathematically, what this question is telling us is that the point P divides the segment AB in the ratio 2:3
We are now tasked with finding the coordinates of point B
For point P to have divided the segment in that particular ratio, then, internal division formula would have been used.
Mathematically, the internal division formula is given as;
(x,y) = (mx2 + nx1)/(m + n) , (my2 + ny1)/(m + n)
In this particular question case;
(x,y) are coordinates of p = (8,1)
x = 8 , y = 1
m = 2 , n = 3
x1 = -2 , y1 = 3
x2 = x , y2 = y ( coordinates of point B)
So let’s make the substitution;
(8,1) = 2x + 3(-2)/2+3) , 2(y) + 3(3)/(2+3)
(8,1) = (2x-6)/5 , (2y + 9)/5
So therefore; let’s equate
(2x-6)/5 = 8
and 2y+ 9/5 = 1
2x-6/5 = 8
2x -6 = 8*5
2x -6 = 40
2x = 40 + 6
2x = 46
x = 46/2
x = 23
(2y + 9)/5 = 1
2y + 9 = 5 * 1
2y + 9 = 5
2y = 5-9
2y = -4
y = -4/2
y = -2
So the coordinates of point B are (23,-2)

Zoey signed up for a streaming music service that costs $7 per month. The service allows Zoey to listen to unlimited music, but if she wants to download songs for offline listening, the service charges $0.75 per song. How much total money would Zoey have to pay in a month in which she downloaded 45 songs? How much would she have to pay if she downloaded s songs?
Answer:
the answer is 60 $ but with the charge of 7 its 67.
Step-by-step explanation:
45 divided by 0.75 is 60.
Answer:
Cost for 45 songs: 40.75
Cost for s songs: 0.75s + 7
Step-by-step explanation:
Since its $0.75 per song, you have to multiply 0.75 to 45. You already need to pay $7. The equation would be 0.75s + 7 and the answer would be 40.75.

-2(x-3) < 2x - 4
Answer:
2.5 < x or 5/2 < x
Step-by-step explanation:
Start by distributing the -2 to the parenthesized numbers.
-2*x and -2*-3
You end up with -2x and 6 (negative times a negative gets positive).
-2x+6 < 2x-4
Next you need to get your variables, x, on one side. It can be either but I like addition so lets take the -2x and move it to the opposite side.
You'll need to add 2x to both sides since its a negative number.
-2x(+2x)+6 < 2x(+2x)-4
-2+2 is 0 and 2+2 is 4.
6 < 4x-4
You want to get the variable alone now so you'll want to add the 4 to the other side (because its negative you add. If it was positive you'd subtract).
6(+4) < 4x-4(+4)
6+4 is 10 and -4+4 is 0.
10 < 4x
You want to divide out the 4 from 4x because you want the variable alone. Divide 4 from both sides
10(/4) < 4x(/4)
Now depending on if you want a variable or a fraction 10/4 can be 5/2 (simplified fraction) or 2.5 (decimal). 4x/4 gives you x.
2.5 (or 5/2) < x
Hope that helps.

After one month, Paul bought 21 passes and spent a total of $33.30.
Help pls
Answer:
Paul spent 6 dollars on the student discount card.
Step-by-step explanation:
If each pass is $1.30, simply divide 21 by 1.30
You should get 27.30
Next, subtract 33.30 by 27.30, getting 6.
18.194 rounded to the tenths
Answer:
18.2
Step-by-step explanation:
To round 18.194 to the nearest tenth consider the hundredths’ value of 18.194, which is 9 and equal or more than 5. Therefore, the tenths value of 18.194 increases by 1 to 2.
18.194 rounded to the nearest tenth = 18.2

Is 5 1/2 rational or irrational ?
Answer:
Rational
Step-by-step explanation:
It is a rational number because any number that can be rewritten as a simple fraction is a rational number. This means that natural/counting numbers, whole numbers and integers, like 5, are all part of the set of rational numbers as well because they can be written as fractions, as are mixed numbers such as 1 ½.

On a piece of paper graph y= 2x-3. Then determine which answer matches the graph you drew. (there is 4 options not just three)
Answer:
A
Step-by-step explanation:
since the slope (2) is positive the graph is similar to y=x, so graphs B and D are eliminated
so when x=1 we have
y=2(1)-3
y=2-3
y=-1
so the point is (1,-1), graph C eliminated
so it's A
The standard equation for finding the equation of a line is expressed as
y = mx + b
m is the slope of the line
b is the y-intercept
Before we can plot the equation of a line, we must know the slope and the y-intercept of such line.
Given the equation of a line to be plotted expressed as y = 2x - 3
Compared with the standard equation;
mx = 2x
m = 2
Hence the slope of the line is 2
Similarly;
b = -3
Hence the y-intercept is 3.
