How do I solve 3/4n+2/3=11/6
Leni [432]

Answer:

n=14/9

Step-by-step explanation:

3/4n+2/3=11/6

3/4n=11/6-2/3

3/4n=11/6-4/6

3/4n=7/6

n=(7/6)/(3/4)

n=(7/6)(4/3)

n=28/18

simplify

n=14/9

In an arithmetic sequence {an}, if a1 = 5 and d = 3, find a72. A) 216 B) 218 C) 221 D) 223
Phoenix [80]

The arithmetic sequence with the given condition is determined recursively by

\begin{cases}a_1=5\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}

So we have

a_2=a_1+3

a_3=a_2+3=a_1+3(2)

a_4=a_3+3=a_1+3(3)

and so on with the general pattern

a_n=a_1+3(n-1)

This means the 72nd term in the sequence is

a_{72}=a_1+3(72-1)=5+3(71)=218

so the answer is B.

For this equation, give two values for x for which the value of y is negative. <br> (y= -2x-5)
Vinil7 [7]

Answer:

Value 1: -2

Value 2: 10

Step-by-step explanation:

To make y negative, -2 ≤ x ≤ ∞

In other words, x must be equal to or greater than -2 for the value of y to be negative.

Value 1: -2

y = -2(-2) - 5

y = 4 - 5

y = -1

Value 2: 10

y = -2(10) - 5

y = -20 - 5

y = -25

Apply Laws of Exponents to write an equivalent expression.<br> (3y)-4. (2z)-4
Stels [109]

After Applying Laws of Exponents we can write as (6yz)^{-4}

<h3>What is law of exponents ?</h3>

The exponent of a number indicates how many times a number has been multiplied by itself. For instance, 34 indicates that we have multiplied 3 four times. Its full form is 3 3 3 3. Exponent is another name for a number's power. A whole number, fraction, negative number, or decimal are all acceptable.

<h3>How are powers of powers multiplied?</h3>

Exponents with distinct bases and the same powers can be multiplied by multiplying the bases and writing the power outside of the brackets.

a^{n} .b^{n} =(a.b)^{n}

=3y^{-4} . 2z^{-4}

=3y^{-4} . 2z^{-4}

= (6yz)^{-4}

I don't understand these I need help
kozerog [31]
F(x) . g(x) means that you have to multiply both functions.

This is how you do it:

\frac{4x^2 + 6}{2}.  \frac{3}{2x^2+3} =  \frac{2(2x^2+3).3}{2.(2x^2+3)}= 3

Note that I have simplified the expressions that are common in the numerator and denominator.

Answer: option D. 3
