Answer:

  • D. The experimental data does not support Sally’s hypothesis.

Step-by-step explanation:

<u>Sally's hypothesis can be shown as:</u>

  • 8c = 1p, where c- coil, p- paper clip

<u>From the data in the table we can see that:</u>

  • 8c = 2p ⇒ 4c = 1p
  • 16c = 4p ⇒ 4c = 1p
  • 24c = 6p ⇒ 4c = 1p

As we see there is a difference, Sally can pick up one paper clip for each 4 coils.

Correct answer choice is D.

I need how you found the answers?

Answer:

2x + 6 = -18

x + 1 = -11

3x = -36

Step-by-step explanation:

First find the solution! Then you can create your own equations

2x+9=-15

2x=-24

x=-12

Thus u need solutions with:

x = -12

Knowing the equation of a line as:

y = mx + b

we can can start by making y = -12 (our solution)

mx + b = -12

Now we can pick a value for m and b by adding and miltiplying on both sides

We do this to keep both sides equal.

if we make m = 2 and b = 3:

2x + mb = -12*m + 2b

2x + 6 = -24 + 6

2x + 6 = -18

Solving this we also get x = -12, as we expect.

An alternative way to think about it is to imagine that we start with a simple equation and make it more complex. We have our solution:

x = -12  => lets add a b value!

x + b = -12 + b => Lets add a slope (m)

xm + bm = -12m + bm

Giving values for this can give you multiple equation of the same solution.

General Formula:

m(x+b) = m(y+b)

mx + bm = my + bm
