Find the inverse of function f.<br> f(x) = 1 /2x+7

ivanzaharov [21]

Answer:

f^-1/2(x)=x/1/2-7/2

Step-by-step explanation:

Replace f(x) with y

Y=1/2x+7

Interchange the variable

X=1/2y+7

Solve For y

Rewrite the equation as

1/2y+7=x

Add -7 to both side

1/2y+7-7=x-7

1/2y=x-7

Divide each term with 1/2

1/2y/1/2=x/1/2-7/1/2

Y=x/1/2-7/2

Solve for hand replace with f^-1/2(x)

f^-1/2(x)=x/1/2-7/2

What is negative 3 times 67

BartSMP [9]

Negative 34 means (-34)

times means to multiply, then

$-34\times1567$

To do it without a calculator we will make -34

-30 + -4, then multiply -30 by 1567 and multiply -4 by 1567 then add the two answers

$-4\times1567=-6268$ $-30\times1567=-47010$

Then add the answers

$-34\times1567=-6268+-47010=-53278$

The answer is -53278

What is the sum of the arithmetic series

docker41 [41]

Answer:

$S_ {12} = 192$

Step-by-step explanation:

The nth term of the given arithmetic sequence is

$U_n = 3 + 2n$

The first term of this series is:

$U_1 = 3 + 2(1) = 5$

The last term of this series is when

$n = 12$

$U_ {12}= 3 + 2(12)$

$U_ {12}= 3 + 24 = 27$

The sum of the first n terms of an arithmetic series when the first an last term is known is given by:

$S_n = \frac{n}{2}(a + l)$

Where a=5 is the first term and l=27 is the last term.

$S_ {12} = \frac{12}{2}(5 + 27)$

$S_ {12} =6(32) =19 2$
