Hi!
Let's write the equation in number form first.
7 over 8
7/8
minus 1
7/8 - 1
over x
7/8 - 1/x
equals 3
7/8 - 1/x = 3
over 4
7/8 - 1/x = 3/4
Now to find the value, let's put each option as the value for x.
A. x = 1
7/8 - 1/1 = 3/4
7/8 - 1 = 3/4
0.875 - 1 = 0.75
-0.125 = 0.75
This is wrong.
B. x = 2
7/8 - 1/2 = 3/4
7/8 - 0.5 = 3/4
0.875 - 0.5 = 0.75
0.375 = 0.75
This is wrong.
C. x = 4
7/8 - 1/4 = 3/4
7/8 - 0.25 = 3/4
0.875 - 0.25 = 0.75
0.625 = 0.75
This is wrong.
D. x = 8
7/8 - 1/8 = 3/4
7/8 - 0.125 = 3/4
0.875 - 0.125 = 0.75
0.75 = 0.75
This is correct!
The answer is d. x = 8
Hope this helps! :)

Answer:
Step-by-step explanation:
y = x² + x - 3
x = - 3
y = ( - 3 )² + ( - 3 ) - 3 = 3
( - 3 , <em>3</em> )
x = 0 ⇒ y = - 3
( 0 , <em>- 3</em> )
x = 1
y = ( 1 )² + ( 1 ) - 3 = - 1
( 1 , <em>- 1 </em>)
<em>(b).</em> Coordinate x of the vertex of quadratic equation y = ax² + bx + c is
-
x = -
= -
= - 0.5
y = ( - 0.5 )² + ( - 0.5 ) - 3 = - 3.25 = - 3
( -
, - 3

Answer:
Therefore,
The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.
Step-by-step explanation:
To Find:
arcsin(0) in degrees =?
Solution:
' arcsin ' a mathematical function that is the inverse of the sine function.
Therefore, arcsin (x) is called the inverse sine function.
It is the angle whose sine is the number x.
So here we require angle in degree for which the Sine is '0'.
It is also written as

We Know that

Therefore,

Also integer multiples of 180° will have

Where n = integer
Therefore for '0' we can have 2×180° , 3×180° , 4×180°....and so on i.e 360° , 540° and so on
Therefore,
The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.
Answer:
9, y=9
Step-by-step explanation:
So, there is one thing we always need to remember to find the y intercept.
This is that the y intercept can always be found on the middle line of the graph, when x is at 0.
What we must do is look at the graph, look at where the function hits x=0, and see what the y value is.
In this case, when x equals 0, we can see that y is 9.
So the y intercept is 9.
Hope this helps! :D
