Answer:
Option B is correct.
Step-by-step explanation:
To find the inverse of the function, the ordered pairs are inverted. i.e. x becomes y and y becomes x.
So, We are given in the table:
(20,52) ,(25,67.5), (30,84)
The inverse would be:
(52,20), (67.5,25),(84,30)
So, Option B is correct.
Answer:
Step-by-step explanation:
Answer:
x=5,y=3
Step-by-step explanation:
the first step is to decide whether you want to substitute y and find x, or substitute x and find y.
(it doesn't matter which way you will choose.If you do the math correctly you will get the correct answer,one way or another).
for example, let's substitute y into the first equation:
x=17-4*(x-2)
so now,we will organize the equation:
x+4x=17+8
5x=25/(÷5)
x=5
now we will substitute x with 5 in the second equation(or the first one,it doesn't matter)in order to find y:
y=5-2
y=3
