The equation y = 36 + 18x models the relationship
between the height y, in inches, of a typical golden
delicious apple tree and the number of years, x, after
it was planted. if the equation is graphed in the
xy-plane, what is indicated by the y-intercept of the
graph?
a) the age, in years, of a typical apple tree when it
is planted
b) the height, in inches, of a typical apple tree
when it is planted
c) the number of years it takes a typical apple tree
to grow
d) the number of inches a typical apple tree grows
each year

Option B) The height, in inches, of a typical apple tree

Step-by-step explanation:

Let

x----> the number of years, after the tree was planted

y ---> the height in inches, of a typical golden  delicious apple tree

we have

Remember that

The y-intercept is the value of y when the value of x is equal to zero

In this problem

The y-intercept is the height of the tree when it was planted (x=0)

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
