Answer:

y ≤ 3x- 1

Step-by-step explanation:

The line is solid, so your answer must have a ≤ or ≥ symbol. And the area below the line is shaded so you would also know you answer must have a ≤ or < symbol.

Answer:

y\leq 3x-1.

Step-by-step explanation:

The graph is a straight line, so its formula is y = ax+b.

You can easily see that two points (0, -1) and (1, 2) belong to the line. Therefore, we have a system of equations:

\left \{ {{0a+b=-1} \atop {1a+b=2}} \right.

By solving it we have:

\left \{ {{a=3} \atop {b=-1}} \right.

So the line is y=3x-1.

The purple region is below the line (including the line), so we choose the answer y \leq 3x-1.

Aleksandr [31]

Answer:

5

Step-by-step explanation:

for the first gear

revolutions/teeth

1 / 24

2 / 48

3 / 72

4 / 96

5 / 120

6 / 144

for the second gear

revolutions/teeth

1 / 40

2 / 80

3 / 120

4 / 160

<em>the two marks will meet after 120 teeth, 5 revolutions of the first gear and 3 revolutions of the second.</em>

the way to get that amount of teeth is

24 = 2 \times 2 \times 2 \times 3 =  {2}^{3}  \times 3

40 = 2 \times 2 \times 2 \times 5 =   {2}^{3}  \times 5

the Least Common Multiple equals the product of all factors, but those factors who are repeted for both numbers should be only once.

{2}^{3} \times 5 \times 3 = 120

120 teeth are 5 revolutions for gear1 and 3 por gear2
