Let f(x) = 2x + 5 and g(x) = x2 − 3x + 2. Perform the function operation. (f + g)(x)

A. x2 + 5x + 7
B. x2 − x + 7
C.7
D.−5x + 7

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
