Answer:

  y = (y2 -y1)/(x2 -x1)x +(y1 -(y2 -y1)/(x2 -x1)x1)

Step-by-step explanation:

You can use two points (x1, y1) and (x2, y2) from the table to make the following computations:

The slope (m) is ...

  m = (y2 -y1)/(x2 -x1)

and the y-intercept (b) can be computed from ...

  b = y1 -m(x1)

Then put these into your equation ...

  y = mx +b

forsale [732]

Answer:

x=5

Step-by-step explanation:

x^2+25-10x = x^2-25

-x^2               -x^2

25-10x = -25

-25        -25

-10x = -50

x=5

lets check

(5-5)^2 = 5^2-25

0^2 = 25-25

0 = 0

She used 477 with the fourth age

A parent donated 2,600 pipe cleaners

Therefore the number of pipe cleaners she have left can be calculated as follows
