Answer:
21
Step-by-step explanation:
The x intercept is represented by the coordinate (x,0) on x axis.
So, to find the x intercept ,we need to equate y=0 in the equation 20x+70y=420
=> 20x+ 70*0=420
=> x=420/20 =21.
x intercept is (21,0).
Relation t is a function because it has no repeating x values
the inverse of relation t is when u switch the x and y values.
ex. inverse of (0,-2) is (-2,0).
and yes, the inverse of relation t is also a function because there are no repeating x values.
