Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.

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 )

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

m∠a is 90°

m∠b is 40°
