Answer:
g(f(x)) = 6x - 9
Step-by-step explanation:
To find g(f(x)), substitute x = f(x) into g(x) , that is
g(3x - 5)
= 2(3x - 5) + 1 ← distribute parenthesis and simplify
= 6x - 10 + 1
= 6x - 9
Answer:
2x+2
Step-by-step explanation:
6x - 4x = 2x
-3 -(-5) = 2
-3 +5 = 2

Sin a * cos b + cos a * sin b=sin (a+b)
sin 78 * cos 42 + cos 78* sin 42=sin (78+42)=sin 120=sin(180-120)=
sin 60=√3 / 2
Answer: sin 78 * cos 42 + cos 78* sin 42=<span>√3 / 2</span>
Answer:
Coordinate geometry (or analytic geometry) is defined as the study of geometry using the coordinate points. Using coordinate geometry, it is possible to find the distance between two points, dividing lines in m:n ratio, finding the mid-point of a line, calculating the area of a triangle in the Cartesian plane, etc.
