The answer is y-4=3[(x-(-4)]

This is because of the formula y-y1=m(x-x1)

$\frac{1}{6} + \frac{1}{12}$

We know that:

$\frac{a}{b} + \frac{c}{d} = \frac{a.d + b.c}{bd}$

So,

$\frac{1}{6} + \frac{1}{12} = \frac{1.12+6.1}{6.12}$

$\frac{12+6}{72}$

$\frac{18}{72}$

$\frac{9}{36}$

$\frac{3}{12}$

$\frac{1}{4}$

In the geometric progression 1, 2, 4… what term is 512?

Levart [38]

The next term is double the previous term, so that the $n$ -th term is given recursively by

$\begin{cases}a_1=1\\a_n=2a_{n-1}&\text{for }n>1\end{cases}$

This rule tells us that

$a_2=2a_1$

$a_3=2a_2=2^2a_1$

$a_4=2a_3=2^3a_1$

and so on, with the explicit rule

$a_n=2^{n-1}a_1=2^{n-1}$

for $n\ge1$ .

If 512 is the $k$ -th term in the sequence, then

$512=2^{k-1}\implies\log_2512=\log_22^9=\log_22^{k-1}\implies9=k-1\implies k=10$

Identify the graphed linear equation.

alukav5142 [94]

Answer:

Step-by-step explanation:

to find the value of the constant at the end of the equation, look for where the line meets the y-axis (here it is +1). Since all of the answer choices have 4 as a slope, looking to see if the line is going down or up will tell you if it's -4 or +4. (here it is negative)
