Answer:
Step-by-step explanation:
Common ratio r = a₂/a₁ = -9/27 = -⅓
b(1) = 27
b(n) = b(1)rⁿ⁻¹ = 27(-⅓)ⁿ⁻¹
The inequality can be simplified to -5 ≤ x < 3, so the solution set is:
[-5, 3)
<h3>
How to solve the inequality for x?</h3>
I assume that the inequality is something like:
-4 ≤ 2*x + 6 < 12
To solve this for x, we need to isolate the variable in one of the parts of the inequality.
To do that, we can perform the same operation in the 3 sides.
If first we subtract 6 in all the sieds of the inequality we get:
-4 - 6 ≤ 2*x + 6 - 6 < 12 - 6
-10 ≤ 2*x < 6
Now we can divide by 2, so we get:
-10/2 ≤ 2*x/2 < 6/2
-5 ≤ x < 3
So we can conclude that the solution set of that inequality is [-5, 3)

C. because you would put in the number for an example 4=2(2) and 2+4=6
Answer:
α ≈ 76°
Step-by-step explanation:
The vertices of a rectangle are right , that is 90°
Using the tangent ratio in right triangle ABC
tanα = = = = 4, then
α = (4) ≈ 76° ( to the nearest degree )
Answer:
The 4 packages of 15 tops for $18 is a better deal
Step-by-step explanation:
We can see which set of tops have the lowest unit price.
4 packages of 15 tops for $18:
4*15=60
There is a total of 60 tops for $18, which means each top costs 18/60 dollars, or $0.30.
5 packages of 10 tops for $16
5*10=50
There is a total of 50 tops for $16, which means that each top costs 16/50 dollars, or $0.32.
0.32>0.3
The 4 packages of 15 tops for $18 is a better deal :)
Have a great day
