Rate of change=R∆=(y2-y1)/(x2-x1)=∆y/∆x
(X1,Y1)(X2,Y2)
(1,2)(2,4)
R∆=∆y/∆x
=(4-2)/(2-1)
R∆=2
(2,4)(3,8)
R∆=(8-4)/(3-2)
R∆=4
(3,8)(4,16)
R∆=(16-8)/(4-3)
R∆=8
Answer:
Step-by-step explanation:
Diameter = 72 inches
radius r = 72/2 = 36 inches
Area = πr²
= 3.14* 36 * 36
=4069.44 inches²²
Answer:
y + 13 = 5(x + 2)
Step-by-step explanation:
1) Find m(the slope of the equation):
Since the slope-intercept form is already given, then you can obtain the slope from it by using y = mx + b
m=5
2) Substitute the given point into the point-slope form y - y1 = m(x - x1)
y-(-13) = 5(x - (-2))
y + 13 = 5(x + 2)
I think it would be 75 cookies because to get to 1 to 25 you multiply by 25, so you multiply 3 by 25 to get 75.
