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.
Your fraction that is equal to 3/12 is 1/4
In standard form the two equations are
7x +y = 5
7x +y = -5
The equations describe lines that are parallel.
1) The graph consists of three horizontal segments, with discontinuities (jumps) at x = 1, x = 2, and x = 3.
A horizontal segment at y = - 2 for the values x = 0 to 1.
A horizontal segment at y = - 1 for values x = 1 to 2
A horizontal segment at y = 0 for values x - 2 to 3.
2) To know whether the end points of a segment are defined by the left or the right values you have to look for the circle at the extreme of the segment: if it is a solid dot, means that the end is included, if is is an open circle (white inside) then the end is not included in that segment.
3) That function is based on the function named integer part because if relates y with the integer part of x.
The integer value function is [x] and it makes correspond y values witht he integer values of x.:
y = 0 witht the integer value of x for x between 0 and 1, excluding 1.
y = 1 with the integer value of x between 1 and 2 (excluding 2)
y = 2 with the integer value of x between 2 and 3 (excluding 3)
y = 3 with the integer value of x between 3 and 4 (excluding 4)
But our function is two units below, so it is [x] - 2
Answer:
the correct answer is -5 since y=7
