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)
The x-intercept of the graph is (4 , 0)
Step-by-step explanation:
Let us revise the meaning of x-intercept and y-intercept
- x-intercept means value x when y = 0
- That means the graph intersects x-axis at point (a , 0), where a the value of x when y = 0
- y-intercept means value of y when x = 0
- That means the graph intersects y-axis at point (0 , b), where b is the value of y when x = 0
∵ 5x - 4y = 20 is the equation of the graph
- To find x-intercept substitute y by 0
∵ y = 0
∴ 5x - 4(0) = 20
∴ 5x - 0 = 20
∴ 5x = 20
- Divide both sides by 5
∴ x = 4
The x-intercept of the graph is (4 , 0)

How to find the extrema of the given function?</h3>
Here we have:
Notice that this is a quadratic equation of negative leading coefficient.
Then we have a maximum at the vertex, and both arms tend to negative infinity as x tends to infinity or negative infinity.
The vertex is at:
x = -(-4)/(2*(-2)) = -1
The maximum is:

Answer:
Step 1: Add 8 to each side. 6x = 2x - 24
Step 2: Add 2x to each side. 8x = -24
Step 3: Divide each side by 8. x = -3
