Answer:
x = 2
Step-by-step explanation:
x/(x+1) = (x+6) / (x+10)
the 10 comes from 9+1
Then cross multiply and solve for x
the terms cancel out just leaving behind a nice linear function.
Marbles are solid in nature, they can be used to form objects of any kind, this makes them suitable for Sam's claim, the marbles can be used to model a typical structure of a solid, even though it is can only be a prototype.
<h3>
There are two main categories of solids:</h3>
- Crystalline
- Amorphous.
Crystalline solids are well ordered at the atomic level, and amorphous solids are disordered.
<h3>
Types of crystalline solids</h3>
There are four types of crystalline solids: ionic solids, molecular solids, network covalent solids, and metallic solids
The constituents of a solid can be arranged in two general ways: they can form a regular repeating three-dimensional structure called a crystal lattice

First thing to do is find out the coordinates of two points on the graph (I will use the ones that have been marked by the red dots):
Point A: (3, -1)
Point B: (1, 2)
Then we will use the slope formula to work out the slope:
y₂ - y₁ / x₂ - x₁
Substitute in our points:
2 - (-1) / 1 - 3
Then we work out the expression (remember a negative and a negative make a positive!):
3 / -2
Then we check if we can simplify this fraction, which in this case we cannot.
Therefore the slope of that line would be:
3 / -2
(remember to write it as a fraction!)
Answer:
The final equation is 
Step-by-step explanation:
The slope of the line CB where, C(0,3) and B(12,-6) will be
Now, if the line perpendicular to the line CB has slope N, then M × N = - 1
⇒ 
{Since 
}
Now, equation of the straight lines which are perpendicular to CB will be in slope-intercept form
{Where, c is the y-intercept}
If this straight line passes through the point (7,4), then
⇒ 12 = 28 + 3c
⇒ 3c = - 16
⇒ 
Therefore, the final equation is (Answer)
