Answer:
D
Step-by-step explanation:
The equations are
● 4x + 2y = 10 (1)
● 4x - 2y = -10 (2)
● 4x + 2y = 10
Add - 4x to both sides
● 4x + 2y -4x = 10 -4x
● 2y = 10 -4x
Divide both sides by 2
● 2y/2 = (10 - 4x)/2
● y = 5 - 2x
● y = -2x + 5 (1)
● 4x - 2y = -10
Add -4x to both sides
● 4x -2y -4x = -10 - 4x
● -2y = -10 - 4x
Divide both sides by -2
● -2y/-2 = (-10 -4x)/-2
● y = 10 + 2x
● y = 2x + 5 (2)
So the equation are
● y = 2x + 5
● y = -2x + 5
Graph them
The lines intersect at (0,5) but aren't perpendicular
So the answer is d
The next set is the parametric equations of the same line .
x = t, y = 5 and z = -t .
What is the meaning of parametric and non parametric?
- The assumptions behind parametric statistics relate to the population's distribution from which the sample was drawn.
- Since no presumptions are made while using nonparametric statistics, data can be gathered from samples that do not fit any particular distribution.
x + y + z = 5, x + z = 0
the line satisfies
x + z = 0 , y = 5
thus
x = t, y = 5 and z = -t .
the first one is technically already the symmetric equations of the line.
thus:
x = -z ; y = 5
the next set is the parametric equations of the same line .
x = t, y = 5 and z = -t .

Answer:
The overall change is $1903.22
Step-by-step explanation:
Let us approach this problem step wise
1.Firstly let us calculate all 12 withdrawal of $175.25
12*$175.25= $2103
2. Let us calculate all the deposits made 17* $235.66 = $4006.22
With these figures we can calculate the overall changes as
= $4006.22-$2103= $1903.22
