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.

Rufina [12.5K]

Step-by-step explanation:

m > 1 = 3y  + 6\\  \frac{m >  -1 - 6}{3}  =  \frac{3y}{3}  \\ y =  \frac{m >  - 5}{3}

R = sec(θ) − 2cos(θ), where -π/2 &lt; θ &lt; π/2
Alex

Answer:

  y = (x/(1-x))√(1-x²)

Step-by-step explanation:

The equation can be translated to rectangular coordinates by using the relationships between polar and rectangular coordinates:

  x = r·cos(θ)

  y = r·sin(θ)

  x² +y² = r²

__

  r = sec(θ) -2cos(θ)

  r·cos(θ) = 1 -2cos(θ)² . . . . . . . . multiply by cos(θ)

  r²·r·cos(θ) = r² -2r²·cos(θ)² . . . multiply by r²

  (x² +y²)x = x² +y² -2x² . . . . . . . substitute rectangular relations

  x²(x +1) = y²(1 -x) . . . . . . . . . . . subtract xy²-x², factor

  y² = x²(1 +x)/(1 -x) = x²(1 -x²)/(1 -x)² . . . . multiply by (1-x)/(1-x)

  \boxed{y=\dfrac{x\sqrt{1-x^2}}{1-x}}

__

The attached graph shows the equivalence of the polar and rectangular forms.

steposvetlana [31]
The first consignment shows no association between the t-shirt size and the profit. 

In the second consignment, the bigger the t-shirt size, the smaller the profit. There is an inverse relationship between the two variables. 

In the third and fourth consignment, the bigger the size, the larger the profit. There is a direct relationship between the two variables.
