Answer: B) Linear; it can be written as y = -3x-6

We subtract 6 from both sides to go from the original equation to -3x-6 = y

Then we flip both sides to end up with y = -3x-6

This is in slope intercept form y = mx+b with m = -3 as the slope and b = -6 as the y intercept.

One number is 6 more than a second number, the sum of the two numbers is 330. what are the numbers?
maksim [4K]

Let's have the first number, the larger number, be <em>x</em>.  We'll have the second, smaller number be <em>y</em>.

We know that x = y + 6, since x is 6 greater than y.

We also know that 330 = x + y.

Because x = y + 6, 330 = y + 6 + y, which simplifies to 330 = 2y + 6.

Now all we need to do is simplify the equation.  First, we subtract 6 from both sides:

330 - 6 = 324

2y + 6 - 6 = 2y.

So we have 324 = 2y.  Then we divide both sides by 2 to get:

162 = y

Plug in y = 162 into the equation x = y + 6 to get:

x = 162 + 6

x = 168

Let's check to make sure our answer is right.  168 is 6 more than 162.  162 + 168 equals 330.  So our two numbers are 168 and 162.

For the function defined by I = 50/t, what can you say about the relationship between the variables I and t?
sveticcg [70]

Answer:

Inverse proportionality relationship

Step-by-step explanation:

SInce I equals 50 divided by t, we see "t in the denominator, which corresponds to an INVERSE proportionality between these variables (I and t)

A certain forest covers an area of 4600km. Suppose that each year this area decreases by 7.75%. What will the area be after 13 y
wolverine [178]

Answer:

1679.60\ km^2

Step-by-step explanation:

-We can use the exponential decay function to estimate the size after 13 years:

P_t=P_oe^{-rt}

Where:

P_t is the size after t years, t is the time, r is the rate of decay and P_o the original size.

#We substitute and calculate as:

P_t=P_oe^{-rt}\\\\=4600e^{-13\times 0.0775}\\\\=1679.60

Hence, the forest covers 1679.60\ km^2 after 13 years.

The division of whole numbers is commutative. true or false?
AURORKA [14]
'Commutative' means you can work it in the other direction without changing it.
But 1/2 is not the same number as 2/1 . So I guess division is NOT commutative.

In the diagram below , tan theta =square root 3. What is the value of m?
vova2212 [387]

Answer:

m=\frac{\sqrt{3}}{2}

Step-by-step explanation:

we know that

In the diagram

tan(\theta)=\frac{m}{1/2}=2m

tan(\theta)=\sqrt{3}

Equate

2m=\sqrt{3}

m=\frac{\sqrt{3}}{2}
