I believe it may be C. Because, the color changing has nothing to do with the reaction you get.

If my hypothesis is correct, the answer should be B. All answers, A, C, and D are chemical reactions. They are all reactions, but B does not fit the category, so they only answer could really be B. (I debated between both A and B because those are the only answers that can be correct)

GIVING 100 POINTS FOR THIS QUESTION PLS PL SPL SPLS PLS HELPPP!!!!! !!

Answer: 65000$ worth of things

This is edited, because I got it backwards last time.

We need to make 2500, but she only makes 4% of whatever she sells.

That means the equation is

2500 = 0.04x

Now, we just need to divide both sides by 0.04 and we get 65000.

Sorry for the confusion.

Given the sequence 5, -10, 20, -40, the next two numbers in the sequence are 80 and -160. true false

jarptica [38.1K]

It is true because every term is the previous term multiplied by -2. So, -40 x -2 = 80, 80 x -2 = -160

a line with slope 3 passes through point (0,10). What is the y-coordinate of the point on the line with x-coordinate 2

skad [1K]

The y-coordinate is 16

<h3><u>Solution:</u></h3>

Given that a line with slope 3 passes through point (0, 10)

To find the y-coordinate of the point on the line with x-coordinate 2

Which means the point is (2, y)

Let us find the required y co-ordinate using slope formula

<em><u>The slope of line is given as:</u></em>

For a line containing points $(x_1 , y_1)$ and $(x_2 , y_2)$ is given as:

$\text {slope}=m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\text {Here } x_{1}=0 ; y_{1}=10 ; x_{2}=2 ; y_{2}=y$

Given that slope "m" = 3

Substituting the values we get,

$\begin{array}{l}{3=\frac{y-10}{2-0}} \\\\ {3=\frac{y-10}{2}} \\\\ {6=y-10} \\\\ {y=10+6=16}\end{array}$

Thus the y-coordinate is 16
