Answer:
y = 2x +7
Step-by-step explanation:
We are given two points on the growth curve: (weeks, ounces) = (2, 11) or (4, 15).
These can be used to write the equation of a line using the 2-point form:
y = (y2 -y1)/(x2 -1x)(x -x1) +y1
y = (15 -11)/(4 -2)(x -2) +11
y = 4/2(x -2) +11
y = 2x +7 . . . . . y = weight in ounces x weeks after birth

<em>Comment on the problem</em>
There are an infinite number of equations that can be written to go through the two given points. A linear equation is only one of them.
(2y + 5)° = 4y °
- 4y + 2y° = -5°
-2y° = -5°
y =5/2
Answer:
x= 11.87
Step-by-step explanation:
sec(32) = 14 /x
1.18=14/x
x1.18 =14
x= 11.87
