What is the value of x when 2x+1=7?

2 answers:

8 0

The answer would be x = 3.

2x = 7 - 1 ( subtract 1 from both sides )

2x = 6 (simplify 7 - 1 to 6)

x = 6/2 (divide both sides by 2)

x = 3 (simplify 6/2 to 3)

PLEASE HELP. TAKE AT HOME TEST. if u = LN5 and v = LN2, write LN8/15 in terms of u and v. (8/15 is 8 over 25)

astra-53 [7]

Answer:

$\ln( \frac{8}{25} ) = 3v - 2u$

Step-by-step explanation:

We have that

$u= \ln(5)$

and

$v = \ln2$

This implies that;

$5 = {e}^{u}$

and

$2 = {e}^{v}$

Now find and expresion for

$\ln( \frac{8}{25} )$

Which is

$\ln( \frac{8}{25} ) = ln(8) - ln(25)$

$\ln( \frac{8}{25} ) = ln( {2}^{3} ) - ln( {5}^{2} )$

$\ln( \frac{8}{25} ) = 3 ln( {2} ) - 2ln(5)$

$\ln( \frac{8}{25} ) = 3v - 2u$

Figures R,S, and T are all scaled copies of one another. Figure S is a scaled copy of R using a scale factor of 3. Figure T is a

PSYCHO15rus [73]

the scale factor from T to S = 1/2

Explanation:

Let the coordinate of R = (x, y)

Figure S is a scaled copy of R using a scale factor of 3:

S = 3(x, y)

S = (3x, 3y)

Figure T is a scaled copy of S using a scale factor of 2:

S = (3x, 3y)

T = 2(3x, 3y)

T = (6x, 6y)

The scale factor from T to S:

from (6x, 6y) to (3x, 3y): old to new

x axis: new/ old = 3x/6x = 1/2

y axis: new/ old = 3y/6y = 1/2

1/2(6x, 6y) will give (3x, 3y)

Therefore, the scale factor from T to S = 1/2
