1. x2 + 4 > 0 2. x2 + 3x + 2 < 0
3. x2 < 16
4. x2 - x > 20
5. x2 + 2x +1 <0
6. x3 + 2x2 - 4x 38
7. x2 - 6x > -9
8. x2 + 25 50

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

215.92 dollars is the answer

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 )

2/3
