If you eliminate obvious wrong answers you increase your chances of getting the question correct.

Notice the inequality signs are both "equal to" which means a solid boundary line. This means choice B and D can not be correct.

You can test a point that is exclusively in the shaded region of each graph.

x + 2y ≤ 4
-x           -x    solve for y by moving x term
      2y ≤ -x + 4
       ÷2    ÷2   divide both sides of the inequality by 2
y ≤ -1/2x + 2 ← plot 2 on y-axis then move down 1 and right 2 put 2nd point
    shade below the solid line

3x - y ≥ 2 when solved for y → y ≤ 3x - 2 (the inequality sign switched because in the process of solving for y I had to divide by a negative number)

plot -2 on the y-axis then move up 3 and to the right 1 put 2nd point 
   shade below the line

the answer is choice A  only graph where they have shaded below both lines...use the y-intercept as a guide for shading above or below the line... shading where numbers are greater than the y-intercept is shading above the line and shading where numbers are less then the y-intercept is shading below the line

A movie theater has a seating capacity of 333. The theater charges $5.00 for children, $7.00 for students,
pantera1 [17]

Answer:

182 children, 91 adults, 60 students

Step-by-step explanation:

The quantity of adults is x, then the quantity of children are 2x,  the quantity of students is 333-x-2x=333-3x. The charge from all adults is 12x, students gave 7*(333-3x), children gave 5*2x=10x, the sum of all money is 2422

12x+ 7(333-3x)+10x=2422

12x+2331-21x+10x=2422

2331+x=2422

x=91- the amount of adults

1) 91*2=182- the amount of children

333-91-182= 60- the amount of students

X + 7x = 56 + 8

Simplifying x + 7x = 56 + 8 Combine like terms: x + 7x = 8x 8x = 56 + 8 Combine like terms: 56 + 8 = 64 8x = 64 Solving 8x = 64 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Divide each side by '8'. x = 8 Simplifying x = 8

There we go!
X + 3x-10 + 70-x = 180
3x = 120
X = 40

The size of the largest angle is 3x - 10, because it is the biggest side.

Hope it helps, have a great day!
