What two numbers multiply and get 100 and add and get -29??
butalik [34]
X, y - the numbers

The numbers multiply to 100.
xy=100

The numbers add up to -29.
x+y=-29 \\
y=-x-29

Substitute -x-29 for y in the first equation:
x(-x-29)=100 \\
-x^2-29x=100 \\
-x^2-29x-100=0 \\
-x^2-4x-25x-100=0 \\
-x(x+4)-25(x+4)=0 \\
(-x-25)(x+4)=0 \\
-x-25=0 \ \lor \ x+4=0 \\
x=-25 \ \lor \ x=-4 \\ \\
y=-x-29 \\
y=-(-25)-29 \ \lor \ y=-(-4)-29 \\
y=25-29 \ \lor \ y=4-29 \\
y=-4 \ \lor \ y=-25 \\ \\
(x,y)=(-25,-4) \hbox{ or } (x,y)=(-4,-25)

The numbers are -4 and -25.

Find the equation of the line which passes through the point (4, -1), and is parallel to the line with the equation y=1/3x+1.
alekssr [168]

Answer:y=1/3x-7/3

Step-by-step explanation:

1. y-y1=m(x-x1)

  • y+1=1/3(x-4)
  • y+1=1/3x-4/3

2. you need to isolate the variable so subtract 1 from both sides

  • y+1=1/3x-4/3
  •   -1           -1
  • y=1/3x-7/3
