60 POINTS AND WILL MARK BRAINLIEST Given the points A(-1,2) and B(7,14), find the coordinates of the Point P on the directed line segment AB that partitions AB in the ratio 1:3. In the above problem, what is the value of a/(a+b)?

.

The line APB is a line such that AP/PB= 1/3. From the points A and B that we have we can find the distance between those points using the formula d= [(y2-y1)^2=(x2-x1)^2]^1/2

d= 4 (13)^(1/2)

Now the ratio is 1:3. AP= sq rt(13) and PB= 3 sq rt(13)

Using mid point formula the mid point of AB (say Q) = [(-1+7)/2,(2+14)/2]= (3,8).  

Hence the mid point of AQ is P which can found out again using the mid point formula  

P= [(-1+3)/2,(2+8)/2]= (1,5)

Final P=(1,5)

Step-by-step explanation:

I got the same thing as the first person. I honestly have no idea I'm soo sorry! I'm failing my grade as of now and i need to ask some questions thank you so much.

Step-by-step explanation:

I literally got banned 2 days ago and had tons of points but now i have -229 points thank you so much have a great day

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
