It causes the breakdown and decay to the rocks. It occurs when the weather water is slightly acidic.
Answer:
Option B is the correct choice.
Step-by-step explanation:
The graph is attached below.
We have to find the
intercept meaning the value of the point on
when 
So we will put the value of zero
instead of
in our given equation.
So here we have solved it algebraically.

Putting 


Multiplying
both sides.

Adding
both sides.

Dividing with
both sides.

So the x-intercept of the given equation is
which can be written as
in terms of coordinates.
Option B
is the correct choice.
Answer:
y=2x-3
Step-by-step explanation:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
By substitution,
1.5x - 6 = -4.5x + 21
6x = 27
x = 4.5
Hence, y = 1.5(4.5) - 6 = 0.75
Answer:
The answer is;
54.4
Step-by-step explanation:
The given parameter are;
Triangle ΔFGH = Right triangle
The length of segment
= 48
The measure of ∠HFG = 28°
The measurement required = The measure of segment
= x
The measure of ∠FHG = 90° angle opposite hypotenuse side of a right triangle
Therefore, ∠FGH = 180° - ∠HFG - ∠FHG = 180° - 90° - 28° = 62°
∠FGH = 62°
By sine rule, we have;
/(sin ∠FGH) =
/(sin(∠FHG)
By substituting the known values, we have;
48/(sin 62°) = x/(sin(90°)
sin(90°) = 1, therefore, we have;
x/1 = x = 48/(sin 62°) = 54.4 (by rounding the answer to the nearest tenth)
x = 54.4
