15/4 * 8/2 = 120/8 = 15
Answer:
x < 
Step-by-step explanation:
Given
- ax + 4b > 9 ( isolate the term in x by subtracting 4b from both sides )
- ax > 9 - 4b ( divide both sides by - a )
Remembering to reverse the inequality symbol when dividing by a negative quantity, thus
x < 
Answer:
<em>15</em>
<em> + 7x + 12</em>
Step-by-step explanation:
(6x^2 + 7x + 2) - (-9x^2 - 10)
Flip the sign:
- (-9x^2 - 10) becomes + 9x^2 + 10
Combine like terms:
6x^2 + 7x + 2 + 9x^2 + 10
6x^2 + 9x^2 = 15x^2
2 + 10 = 12
Put it all together:
15x^2 + 7x + 12
Answer:
Sₙ=3(1/2^n)
Step-by-step explanation:
Notice that in the given series that each term is being multiplied by 1/2, which is our common ratio. 3/2 is the first term because 3*1/2=3/2, so the expression that defines Sₙ is Sₙ=3(1/2^n)
