Answer:
y - 6 = (-1/2)(x - 4)
Step-by-step explanation:
As we go from (4, 6) to (6, 10), x (the run) increases by 2 and y (the rise) increases by 4. Thus, the slope of the line connecting these two points is m = rise / run = 4/2 = 2.
The slope of a line perpendicular to this one is the negative reciprocal of 2, which is -1/2.
Using the point-slope formula, we get the following equation for the perpendicular line:
y - 6 = (-1/2)(x - 4) ( obtained using the point (4, 6) )
Ths solubility curve is used to show the amount of salt dissolved (solubility).
<h3>What is the solubility curve?</h3>
The solubility curve is a depiction of the solubility of a substance plotted against its temperature. It can be used most times to show the solubility of a susbtance at different temperatures. This question is incomplete hence so we can not be able to obtain the solubility of the salt at this temperature.
If the solubility curve has been shown in the graph, then we can be able to obtain the solubility of the salt from the data shown on the plot.

5x + 2y = 7....multiply by -1
-2x + 2y = -14
----------------
-5x - 2y = -7 (result of multiplying by -1)
-2x + 2y = -14
---------------add
-7x = - 21
x = -21/-7
x = 3
5x + 2y = 7
5(3) + 2y = 7
15 + 2y = 7
2y = 7 - 15
2y = - 8
y = -8/2
y = -4
solution is (3,-4)
The answer is D. If you divide 1000 by 100, it is 10. 10 is equal to 1/100 of its previous value of 1000.
40
I assumed that you wanted to know how much little cubes are in the big cubes...so.....first you need to find out the volume of the small cube : 1/2 x 1/2 = 1/4....then divide it with 10, then results with 40! :D
