Answer:
2) y = x + 2
3) slope: height increases by 1 unit per unit increase in x
Intercept: initial height (at birth) was 2 units
Step-by-step explanation:
Using (38,40) and (48,50)
Slope: (50-40)/(48-38)
= 10/10
= 1
y = mx + b
y = x + b
40 = 38 + b
b = 2
y = x + 2
Oof, division rule:
(f/g)'=(f'g-fg')/g^2
Let (9t-8)^6=f and t+2=g
Thus we get
(9*6(9t-8)^5*(x+2)-(9t-8)^6)/(x+2)^2
(54(9t-8)^5*(x+2)-(9t-8)^6)/(x^2+4x+4)
I'm not sure how much I'm supposed to simplify this...
Two lines in a plane can intersect,overlap or be parallel.When two lines intersect they have a common point which lies on both line.This is called solution of the two simultaneous equation which when graphed represent straight lines. Adding the two equations uses Elimination method to solve for x and y. The x and y value obtained is the common point lying on both the lines.
2x - 3y = 1
+ 2x + 3y = 2
4x =3 Or x=3/4
Substituting x value in any of the two-equation we can find the corresponding y value .
2x-3y=1
2(3/4) - 3y =1
Solving for y
y= 1/6
The point of intersection of the two lines is ( 3/4, 1/6)
