Describe how you can find an equation from a chart. (How do you find the information to plug into the form y=mx+b?)
1 answer:
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

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

If 3/8 equals 3 ft, then i would assume that 5/8 equals 5 ft.
Answer:
3,444
Step-by-step explanation:
The art teacher had 1321 pipe cleaners for a project
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
= 1321-477+2600
= 844 + 2600
= 3,444
