y = -3x - 2

Since a < 0 we have a decreasing line, so it can be only the first or the last

And if we solve the equation for y = 0 we have

0 = -3x - 2

3x = -2

x = -2/3

So, the last one is the right

pantera1 [17]

Answer:

x > -7

Step-by-step explanation:

Step 1: Translate

Twice a number = 2x

Six more = + 6

At least = >

-8 = -8

Step 2: Write out inequality

2x + 6 > -8

Step 3: Solve

2x > - 14

x > -7

Can somebody help me with this plz?!?

fomenos

Answer:

Step-by-step explanation:

The angle is 60 degrees and a whole circle has a total of 360 degrees, of that makes sense. So if you do 360/60, you get 6. This tells you that 6 of those particular arcs fit into this particular circle.

Find the circumference of the circle. You are given the radius, 3. Use the circumference formula, 2(pi)(r). You get 6pi.

6/6 = 1, so the length of that one arc is just p

Hope this helps!.

A marine aquarium has a small tank and a large tank, each containing only red and blue fish. In each tank, the ratio of red fish

Anna007 [38]

Answer:

Ratio of blue fish in the small tank to the red fish in large tank is 10 : 6279

Step-by-step explanation:

Let the number of red fish and blue fish in the large tank are x and y respectively.

Similarly ratio of red fish and blue fish in the small tank are x' and y' respectively.

Since in each tank ratio of the red fish to blue fish is 333 : 444

That means x : y = 333 : 444

Or $\frac{x}{y}=\frac{333}{444}$

⇒ $\frac{x}{y}=\frac{3}{4}$

⇒ y = $\frac{4x}{3}$ --------(1)

Similarly x' : y' = 333 : 444

⇒ $\frac{x'}{y'}=\frac{333}{444}$

⇒ $\frac{x'}{y'}=\frac{3}{4}$

⇒ x' = $\frac{3y'}{4}$ ------(2)

Ratio of the fish in large tank to the fish in small tank is 464646 : 555

So (x + y) : (x' + y') = 464646 : 555

$\frac{x+y}{x'+y'}=\frac{464646}{555}$

Now we replace the values of x and y' from equation (1) and equation (2)

$\frac{(x+\frac{4x}{3})}{(\frac{3y'}{4}+y')}=\frac{464646}{555}$

$\frac{\frac{7x}{3}}{\frac{7y'}{4}}=\frac{464646}{555}$

$\frac{4}{3}\times \frac{x}{y'}=\frac{464646}{555}$

$\frac{x}{y'}=\frac{3}{4}\times \frac{464646}{555}$

$\frac{x}{y'}=\frac{232323}{370}$

$\frac{y'}{x}=\frac{370}{232323}$

$\frac{y'}{x}=\frac{10}{6279}$

Therefore, ratio of blue fish in the small tank to the red fish in large tank is 10 : 6279
