Answer:
x=1
Step-by-step explanation:
it is the point of intersection of both lines which (1,1)
for x=1 both produce same value i.e.,1
The mean absolute deviation shows the average distance number data is from each other. The bigger it is the farther the numbers are away from each other and vice versa.
Answer:
Ray 23
Step-by-step explanation:
Y = |x - 1|
and
y = 3x + 2
Equating the values of y, we can write:
|x - 1| = 3x + 2
This means:
A) x - 1 = 3x + 2
x - 3x = 2 + 1
-2x = 3
⇒ x = -3/2 = -1.5
B) - ( x - 1) = 3x + 2
3x + x = 1 - 2
4x = -1
⇒ x= -1/4 = - 0.25
For x = -0.25
y = 3(-0.25) + 2 = 1.25
x = -1.5 is an extraneous root and is not applicable.
So the solution set is (-0.25, 1.25)
Option A gives the approximate solution set.
Hi...
Ans for the Question 8.
the reflecting line is on the y intercept itself and is perpendicular.
Only the x intercept will change if any other points were reflected over the same line. Since the line is on the y intercept then the only the sign of x will change.
so the answer for 8 is option A
