Step-by-step explanation:

Step 1:

0.6x - 0.1 = 0.5x + 2 Equation

Step 2:

0.1x - 0.1 = 2 Subtract 0.5x on both sides

Step 3:

0.1x = 2.1 Add 0.1 on both sides

Step 4:

x = 2.1 ÷ 0.1 Divide

A geometric sequence has a first term of 3 and a fourth term of 81÷8. Find the eighth term

tatuchka [14]

Answer:

6561 / 128

Step-by-step explanation:

The nth term of a geometric sequence is:

a = a₁ (r)ⁿ⁻¹

The first term is 3, and the fourth term is 81/8.

81/8 = 3 (r)⁴⁻¹

27/8 = r³

r = 3/2

The eighth term is therefore:

a = 3 (3/2)⁸⁻¹

a = 6561 / 128

Please prove it for me

grigory [225]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

tanx = $\frac{1}{cotx}$

Consider the left side

$\frac{cotA-1}{cotA+1}$ ← divide terms on numerator/denominator by cotA

= $\frac{\frac{cotA}{cotA}-\frac{1}{cotA} }{\frac{cotA}{cotA}+\frac{1}{cotA} }$

= $\frac{1-tanA}{1+tanA}$

= right side , thus proven

The given options are:

(A)x+y = 20
(B)7 apps and 14 movies
(C)x-y= 20
(D)y=-x+ 20
(E)8 apps and 12 movies
(F)xy= 20

Answer:

(A)x+y = 20
(D)y=-x+ 20
(E)8 apps and 12 movies

Step-by-step explanation:

If Elizabeth has a combined total of 20 apps and movies.

Where:

Number of apps=x

Number of Movies =y

Then:

Their total,

x+y=20 (Option A)

If we subtract x from both sides

x+y-x=-x+20

y=-x+20 (Option D)

In Option E

8 apps and 12 movies add up to 20. Therefore, this could also apply.
