Step-by-step explanation:
1. What the GCF
the GCF is 4
4(x + 8)
2. divide by 4
4(x+8) is the solution
Answer:
2 (x - 2) (x + 9)

15. 2x+4y=5
Since you want to put it into y-intercept format (y=mx+b) first you want to minus 2x on both sides making it 4y= -2x+5, following you will divide by 4 on both sides making it y= -1/2x+ 5/4(1.25). The slope being -1/2x and the y-intercept hitting 1.25 on the y-axis.
17. 3x-3y=5. Like question 15 you will have to put it into y=mx+b format. So first you would minus 3x on both sides becoming -3y = -3x+5 then do the following: divide by -3 on both sides making the answer Y= x-5/3(-1.66666667) you can round it up to -1.67. Overall the answer should be y=x-1.67. 1.67 being the y-int meaning the line meets the y-axis at 1.67 and the slope being 1/1 to help you form the line.
Answer:
point is (13/4 , 17/2)
Step-by-step explanation:
Let (x1,y1) and (x2,y2) be the end points of a line segment, 'A' is the point on the line segment such that A divides the line segment in the ratio p : q then the coordinates of A (x,y) is given by,
x = x1 + p/w(x2 - x1) and y= y1 + p/w(y2 - y1) where w = p+q
It is given that,
Point A is located at (4, 8) and point B is located at (14, 10) .
Let P be the point on AB such that P divides AB in the ratio 1:3
<u>Find the coordinates of P(x,y)</u>
w = 1+3 = 4
x = x1 + p/w(x2 - x1) = 4 + 1/4(14 -4) = 4 + 10/4 =13/4
y= y1 + p/w(y2 - y1) = 8 + 1/4(10 - 8) = 8 + 1/2 = 17/2
point is (13/4 , 17/2)
