Check all of the points that are solutions to the system of inequalities, y> 2x + 1
y< -2x + 3

Someone help me ASAP please and thank you

  A(0, 2), C(-1, 2), E(-4, -1)

Step-by-step explanation:

It can be useful to graph the equations and plot the points. Only the points in the doubly-shaded area are solutions to the system of inequalities.

You can try the offered points and see which work.

y > 2x +1

  A. 2 > 2·0 +1 . . . true

  B. 3 > 2·1 +1 . . . . False

  C. 2 > 2(-1) +1 . . . true

  D. 1 > 2·1 +1 . . . . False

  E. -1 > 2(-4) +1 . . . true

  F. 0 > 2·0 +1 . . . . False

__

y < -2x +3

  A. 2 < -2·0 +3 . . . true

  C. 2 < -2(-1) +3 . . . true

  E. -1 < -2(-4) +3 . . . true

Points A, C, E are in the solution set.

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
