<span>-24=2(x-4)
Use distributive property
-24=2x-8
Add 8 to both sides
-16=2x
Divide 2 on both sides
Final Answer: -8=x</span>

Answer:
- <u><em>There are 20,000 number available.</em></u>
Explanation:
To determine <em>how many phone numbers are available </em>you need to know how many digits the number contains.
I will assume the same number of digits for other similar questions, i.e. 7.
With 7 digits, the numbers that begin with 373 or 377 can be of the form 373XXXX or 377XXXX.
Where each X can be any digit 0 - 9. Then, there are 10 different options for each X.
Thus, there are 10×10×10×10 = 10,000 different numbers starting with 373 and other 10,000 different numbers starting with 377.
In total, there are 20,000 numbers available.

Answer:
Step-by-step explanation:
For the given piecewise function,
Let the equation of the segment AB is,
y = ax + 7 where x < -2
Since a point (-2, 3) lies on the given line,
3 = a(-2) + 7
3 - 7 = -2a
a = 2
Therefore, f(x) = 2x + 7 when x < -2
For the segment BC,
f(x) = 3 where -2 ≤ x ≤ 2
For the segment CD,
f(x) = bx + 9
Since a point (2, 3) lies on this segment,
f(2) = 2b + 9 = 3
2b = 3 - 9
b = -3
Therefore, equation of segment CD will be,
f(x) = (-3)x + 9 where x > 2
