Answer:
the answer is B
Step-by-step explanation:
it is B cause the line is going up so it is a positive linear function and the more he studies the higher he gets on his test
Answer:
x=5, y=6. (5, 6).
Step-by-step explanation:
-6x+6y=6
-6x+3y=-12
---------------
simplify -6x+6y=6 into -x+y=1 and y=1-(-x)=1+x
-6x+3(1+x)=-12
-6x+3+3x=-12
-3x=-12-3
-3x=-15
3x=15
x=15/3
x=5
-6(5)+6y=6
-30+6y=6
6y=6-(-30)
6y=6+30
6y=36
y=36/6
y=6
Answer:
The inverse of a given function
d) 
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that f(x) = 4x + 12
let y = 4 x + 12
4 x = y - 12

we know that y = f(x)
⇒ x = f⁻¹(y)

Put replace 'y' in 'x'

<u><em>Final answer</em></u><em>:-</em>
The inverse of a given function
