The answer would be B) x = 4.
1.5x + 6 - 3 = 4.5x - 9
1.5x + 3 = 4.5x - 9
3 = 4.5x - 9 - 1.5x
3 = 3x - 9
3 + 9 = 3x
12 = 3x
12/3 = x
4 = x
x = 4.
Answer:
see explanation
Step-by-step explanation:
Use the points to find a and b, that is
(2, 18)
18 = a
→ (1)
(4, 162)
162 = a
→ (2)
divide (2) by (1)
=
= 9
b² = 9 ⇒ b = 3
substitute b = 3 into (1)
18 = 9a ⇒ a = 2
y = 2
← exponential equation
Well first I think you have to do 500-10%=450 Then I think you do 450x15=6750 I hope this helps. :)
2275/6 or 379.1667. You multiply the top (numerators) parts of the fractions and then the bottom (denominators). You then divide them.
