Answer:
31
Step-by-step explanation:
For rectangle ABCD, AC and BD are the lengths of the diagonals. The diagonals of a rectangle are congruent.
AC = BD
3x + 7 = 131 - x
Add x to both sides.
4x + 7 = 131
Subtract 7 from both sides.
4x = 124
Divide both sides by 4.
x = 31

B. Find the value of x when y=0
In this question , it is given that slope of 5 and a y-intercept of (0,-2) .
Now we have to check out the equation of the line that we are gonna use here.
Here we use the slope intercept form, which is
where m is the slope , which is 5 here and y intercept is b , which is -2 here.
Substituting these values in the equation, we will get
Part b .
Now we have to substitute 0 for y, and find the value of x, that is
The graph of y = (3/8)x - 5 and y = (3/8)x + 2 are parallel since both graphs have the same slope.
The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The graph of two equations is parallel if the slope of each of the equations is the same.
The two equations are:
y = (3/8)x - 5 _____(1)
y = (3/8)x + 2 _____(2)
This is in the form of y = mx + c
Where m is the slope.
Now,
From (1 ) and (2) we see that,
m = 3/8
Thus,
The graphs are parallel.

Answer:
AB in terms of rays, can never be BA.
Step-by-step explanation:
AB and BA name the same ray.
No, this is never true. A ray starts from a point and move in a single direction to infinity.
So, if starting point is A and ray is moving towards B, so it will continue moving towards the points further from B.
Therefore, AB as in terms of rays, can never be BA.
