Answer:

Correct choice: D.

$y+4=4(x+3)$

Step-by-step explanation:

The point-slope form of the equation of a line is:

$y-k=m(x-h)$

Where m is the slope and (h,k) is a point through which the line passes.

According to the question, the slope of a line is m=4 and it contains the point (-3,-4), thus, replacing the values:

$y-(-4)=4(x-(-3))$

Operating:

$\boxed{y+4=4(x+3)}$

Correct choice: D.

Step-by-step explanation:

2)

x + 14 $\frac{13}{25}$ = -0.87

x + $\frac{363}{25}$ = - $\frac{87}{100}$

x + $\frac{1452}{100}$ = - $\frac{87}{100}$

x = - $\frac{87}{100}$ - $\frac{1452}{100}$

x = - $\frac{1539}{100}$

3)

x -8 $\frac{5}{6}$ = 1.5

x - $\frac{53}{6}$ = $\frac{9}{6}$

x = $\frac{9}{6}$ + $\frac{53}{6}$

x = $\frac{62}{6}$

x = $\frac{31}{3}$

4)

x - $\frac{7}{12}$ = - 7 $\frac{7}{16}$

x - $\frac{28}{48}$ = - $\frac{119}{16}$

x = - $\frac{357}{48}$ + $\frac{28}{48}$

x = - $\frac{329}{48}$

5)

$\frac{8}{9}$ - x = 6 $\frac{1}{15}$

$\frac{8}{9}$ = $\frac{91}{15}$ + x

$\frac{40}{45}$ - $\frac{273}{45}$ = x

- $\frac{233}{45}$ = x

x = - $\frac{233}{45}$

6)

-33.754 - x = 28.05

-33.754 - 28.05 = x

- 61.804 = x

x = - 61.804

Formula to find the number of subsets of a set that has "n" number of elements. 2 raise 1)to the nth power 2)n squared 3)2 times

KiRa [710]

Answer:

(A) $2^n$

Step-by-step explanation:

Given a set with "n" number of elements, the collection of all subsets of the set is referred to as the Power set of the given set.

To find the number of possible subsets of any set, we use the formula: $2^n$

Take for example the set: A={2,3,4)

A has 3 elements, therefore n=3

The number of possible subsets of A is: $2^3=8$ subsets$
