Aparking lot began with four times as many spaces in a row as rows. after being expanded 5 more rows were added and 9 more spaces in each row . the maximum number of spaces that the parking lot will hold is 469. if r represents the original number of rows, which of the following represents this situation?

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

what is the original number? you forgot to add it.

but which class are u may know that first

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
