Solving for each equation:

A: True.

$\frac{n}{2} +3 *4 = \frac{n}{2}+12\\\\\frac{n}{2} + 12 = \frac{n}{2} + 12$

B: False.

$\frac{1}{3}z+\frac{2}{3}z * 9 = 9z\\\\\frac{1}{3} z+6z = 9z$

C: True, given that y = 1

$-8y +4.3y + 3.7 = 0\\\\-3.7y = -3.7$

D: True, given that b = 6.66667

$12-1.8b+1.8b=1.8b\\12 = 1.8b$

E: True.

$\frac{m}{8} + 7(\frac{m}{8} ) =m\\\\\frac{m}{8} + (\frac{7m}{8} )= m\\\\\\\frac{8m}{8} = m\\$

Is factor and divisor the same thing?

ruslelena [56]

NO. because a factor is multiplied together and a divisor is when you multiply by a quotient

As you can see I keep getting questions wrong.... Can you answer the last question?

aivan3 [116]

Answer:

y = 0

Step-by-step explanation:

It is always a good idea to look at the question and make some observations about it. Here, you might observe ...

all of the bases are powers of 3: 243 = 3^5; 9 = 3^2
y is a factor of every exponent

The latter observation is important, because it means that when y=0, every exponential expression has a value of 1. Hence y = 0 is a solution.

__

To solve the equation, you can write it in terms of powers of 3.

(3^5)^(-y) = (3^-5)^(3y)·(3^2)^(-2y)

3^(-5y) = 3^(-15y)·3^(-4y)

3^(-5y) = 3^(-19y)

-5y = -19y . . . . . . . . equating exponents; equivalent to taking log base 3

14y = 0 . . . . . . . . . . add 19y

y = 0 . . . . . . . . . . . one solution

______

The rules of exponents we used are ...

(a^b)(a^c) = a^(b+c)

(a^b)^c = a^(bc)

1/a^b = a^-b

Answer:

$\text{C. f(x)} = 3(1.5)^{x-1}$

Step-by-step explanation:

The numbers don’t increase by a constant amount, so this is not an arithmetic sequence.

It appears to be a <em>geometric sequence</em>.

The <em>general formula</em> for each term in a geometric sequence is

aₙ = a₁rⁿ⁻¹

===============

Calculate the value of r

You can calculate the r-value by dividing any two consecutive terms in the sequence.

rₙ = aₙ/aₙ₋₁

a₂/a₁ = 4.5/3 = 1.5

a₃/a₂ = 6.75/4.5 = 1.5

a₄/a₃ = 10.125/6.75 = 1.5

a₅/a₄ = 15.1875/10.125 = 1.5

r = 1.5

===============

Determine the formula for the nth term

a₁ = 3; r = 1.5 Substitute the values

aₙ = 3(1.5)ⁿ⁻¹ Write the equation as a function of x

$\text{f(x)} = 3(1.5)^{x-1}$
