Answer:
see explanation
Step-by-step explanation:
Using the laws of logarithms
• log x + log y ⇔ log(xy)
• log x - log y ⇔ log (
)
• log 
⇔ nlog x
Hence
2 
x + 2x - (x - 3)
= x² + 2x - (x - 3)
= 2x³ - (x - 3)
= (
)
Answer:
12%
Step-by-step explanation:
let x represent the actual number of members last year.
current members = 675 and with an increment of 13% over previous year
to find the increment
(675 - x) / x = 0.13
675 - x = 0.13x
collect the like terms
675 = 0.13x + x
675 = 1.13 x
x = approx 597 members were there last year
its hope to increase by the same number next year
percent increase = 675 - 597 / 675 = 78 / 675 = 0.12 = 12%
Answer is 20. -4 x 1 is -4 so it doesn’t change. -4 -8 makes it -4 + 8 as there’s two negatives. 9 divided by 3 is 3. So it’s -4 +8 x 3. 8x3 is 24. So -4 + 24 = 20. Therefore final answer is 20
Answer:
y = -6/5
Step-by-step explanation:
Remove parentheses
2y - 2 - 7y = 4
group like terms
2y - 7y - 2 = 4
add similar elements
-5y - 2 = 4
add 2 to both sides
-5y - 2 + 2 = 4 + 2
simplify
-5y = 6
divide both sides by -5
-5y ÷ -5 and 6 ÷ -5
simplify
y = -6/5
Answer:
9
Step-by-step explanation:
3^5 = 243
3^3 = 27
243 / 27 = 9
Hope this helps :)
