Answer: B. ( -∞ , 0) and C. (1, 2)
<u>Step-by-step explanation:</u>
The y-value is increasing between x = -∞ and x = 0.
The y-value is decreasing between x = 0 and x = 1.
The y-value is increasing between x = 1 and x = 2.
The y-value is decreasing between x = 2 and x = +∞
So, the y-value is increasing at ( -∞ , 0) ∪ (1, 2)

Answer:48
Step-by-step explanation:
125 ÷ 3 = 41.6666666667
41.66666666667 X 2
= 83.3333......
Technically not correct, because you cannot split sixth graders into pieces, so you would probably round it to 84 students.
Answer:
<em>Square= 12 units</em>
<em>Triangle long sides= 19 units</em>
<em>Triamgle short side= 10 units</em>
Step-by-step explanation:
<em>It is a square, so all sides are the same. That means 3x+3 equals 4x. What number can be subsituted into x to equal 4? If x is 3, then 3x+3 would be 3(3)+3. It equals 12. 4 times 3 is also 12. It works! That also means the square's side is 12 units.</em>
<em>Square= 12 units</em>
<em />
<u><em>So, x=3</em></u>
<em />
<em>The triangle's longer sides are 7x-2. Subsitute x in, which is 3, and you get 7(3)-2. It equals 19. The two longer sides of the triangle are the same length, so both are 19 units.</em>
<em>Triangle long sides= 19 units</em>
<em />
<em>The triangles shorter side is 2x+4. Subsitute 3 in for x and you get 2(3)+4. It equals 10, so the shorter side is 10 units.</em>
<em>Triangle short side= 10 units</em>
