Answer:

y = -1/2x - 2

Step-by-step explanation:

If it's parallel, that means that the slope is the opposite of the one in the given equation, meaning that 2 would be flipped and turned negative into -1/2.

Then, fill in the x and y values to get the y-intercept.

1 = -1/2(-6) + b

1 = 3 + b

-2 = b

So your answer is y = -1/2x - 2

Vikki [24]

To find whether the volume would be doubled when the radius is,we can find the volume of the two balloons.

The formula of a sphere is:
$\frac{4}{3} \pi \: {r}^{3}$
Let's take 丌 as 3.14

The volume of the balloon with 4cm radius:
$\frac{4}{3}(3.14) \times {4}^{3} \\ = 4.18667 \times 64 \\ = 267.94688$

The volume of the balloon with 8cm radius:
$\frac{4}{3}(3.14) \times {8}^{3} \\ = 4.18667 \times 512 \\ = 2143.57504$
As we can see,
267.94668 × 2 = 535.89 ≠2145.56

Thus,she wouldn't discover that the volume is twice as big when the radius is doubled.

Hope it helps!

In science class, a student is measuring the temperature of a solution in science experiment. The solution

Radda [10]

Answer:

-11.8

Step-by-step explanation:

<u>Given:</u>

-3.4 to 12.4 increased (difference = 15.8)

12.4 to 20.4 decreased (difference = 8)

20.4 to 3.2 increased (difference = 17.2)

Final temperature.

Solution:

As we noticed, this is a pattern of increase, decrease, increase... (and so on and so forth). From this alone, we have gotten the clue that the temperature is going to decrease. But here is the thing, How far will it decrease?

Use the difference of the starting result to find the ending result.

3.2 - 15

= -11.8

Therefore, the final temperature is -11.8.
