Use only the digits 0 - 9 and the decimal and the negative sign, if needed, to fill in the blank. if f(x) = 2x + 9, then f(-1) =

7

Step-by-step explanation:

Replace both instances of x in f(x) = 2x + 9 with -1:

f(-1) = 2(-1) + 9 = 7

Thus, f(-1) = 7

ian gonna lie that is way to much

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 )
