(g-f)(x)=g(x)=f(x)
(g-f)(x)=6x-4+x^2
(g-f)(x)=x^2+6x-4 then:
(g-f)(3)=3^2+6*3-4
(g-f)(3)=9+18-4
(g-f)(x)=23
Make y the subject in both equations
For the second equation
The two equations are parallel because they have the same gradient or slope but different y intercepts.
This type of equations have no solution because they will never intersect.
The correct answer is C
Jennifer SHE MAKES 12 Minutes
Max makes 11
And Joyce 10
Answer- Jennifer
The answered the question is X=5
Answer:
The distance cover by him walking back is 11.25 miles
Step-by-step explanation:
Given as :
Time for Janelle to spend on training = 5 hours
The running speed of Janelle = 9 mph
The walking back with 3 mph
Let The distance for running and walking is same i.e D miles
SO, Time =
∴ 5 = +
Or, 5 × 9 = D + 3 D
Or, 45 = 4 D
∴ D = = 11.25 miles
Hence The distance cover by him walking back is 11.25 miles Answer
