Answer:
{x I - 12 < x < 7}
Step-by-step explanation:
Fuaad solved an absolute value inequality and expressed the solution as - 12 < x < 7.
So, the value of x lies between - 12 and 7 but not including - 12 and 7.
Option C will give another way to show Fuaad's solution.
It is {x I - 12 < x < 7}, which means x is a variable which belongs with in the interval (- 12, 7). (Answer)
Answer:
r = 4
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 5
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, r ) and (x₂, y₂ ) = (8, 9)
m =
=
= 9 - r = 5 ( subtract 9 from both sides )
- r = - 4 ( multiply both sides by - 1 )
r = 4
Step-by-step explanation:
We have got the lines :

Both lines intercept the x-axis in the point :

In all point from x-axis the y-component is equal to 0.

We replace the I point in the lines equations:

From the first equation :

From the second equation :

Then 
Finally :

y = ax + b and y = cx + d have the same x-intercept ⇔ad=bc
