Absolute value<span> describes the distance of a </span>number<span> on the </span>number<span> line from 0 without considering which direction from zero the </span>number<span> lies. The </span>absolute value of a number<span> is never negative. The </span>absolute value<span> of 5 is 5.</span>
18. s = 5r^2 + 7......making r the subject
s - 7 = 5r^2
(s - 7) / 5 = r^2...by taking the sqrt of both sides, it eliminates the ^2
( sqrt (s-7)/5) = r
19. h = ut - 1/2gt^2....u = 100, t = 1 4/5(or 9/5)...g = 6.4
h = (100)(9/5) - 1/2(6.4)(9/5^2)
h = 180 - 1/2(6.4)(3.24)
h = 180 - 3.2(3.24)
h = 180 - 10.368
h = 169.632 or 169 79/125
20. sorry..do not know this one

Answer:
In programming, a recursive function is a function that calls itself. Recursion is used very commonly in programming, although many simple examples (including some shown in this section) are actually not very efficient and can be replaced by iterative methods (loops or vectorized code in MATLAB).
Step-by-step explanation:
Answer:
-12
Step-by-step explanation:
6 + 1.5x = -12
1.5x = -18
x = -12
