Step-by-step explanation:
conditions : x≠0 and x≠-a and b≠1
1/(x+a) = b/x ⇌ 1×x = b(x+a) ⇌ x = bx + ba ⇌ (1-b)x = ab ⇌ x = ab/(1-b)
Hello! You should select a, b, and c.
Think of it like on a number line, x could be 5, or -5 and still be the same distance from 0. Absolute vales are the same way, so if the answer is 5 or -5, its right! It cant be the last one because x, must only be 5 or -5. Hope that helps!
Answer:
B
Step-by-step explanation:
Since the inequality sign is greater than or equal to, we need a solid line with the color filled at the top of the graph. This already eliminates answer choice A or D.
Since we know it has to have a solid line, the answer is B.
Idk what the hell all that is but x = 1.802775637731995
4x^2 - 13 = 0
4x^2 = 13
13/4=3.25
x^2 = 3.25
x = ~1.8
Answer:
D
Step-by-step explanation:
4 people = 15 days
1 people = 15/4 = 3.75
so, 6 people = 3.75 × 6
= 22.5
