If you use the same technique from the first question, you can do:

5x+2=3x+42
2x=40
x=20

For the rest of the questions, please use the same technique if they are vertical because I can't solve all of the questions for you sorry.

Answer: $x = 5 , \frac{-1}{3}$

Step-by-step explanation:

$8(^{x^{2}-\frac{14}{3}x}) = 32$

This could be written in index form as :

$2^{3}( ^{x^{2}-\frac{14}{3}x})=2^{5}$

By laws of indices , we will equate their power , that is :

$3(x^{2} -\frac{14}{3}x) = 5$

Expanding , we have :

$3x^{2} -14x=5$

$3x^{2} -14x-5=0$

factorising the Quadratic equation , we have :

$3x^{2} -15x + x -5=0$

$3x(x-5)+1(x-5)=0$

$(x-5)(3x+1) = 0$

Therefore:

$x-5 = 0$ or $3x+1=0$

$x = 5 , \frac{-1}{3}$

The price of an item yesterday was $120. Today, the price rose to $294. Find the percentage increase.

Blizzard [7]

Answer:

145%.

Step-by-step explanation:

Given that the price of an item yesterday was $120, and today, the price rose to $294, in order to find the percentage increase, the following calculation has to be made:

120 = 100

294 = X

((294 x 100) / 120) = X

29,400 / 120 = X

245 = X

245 - 100 = 145

Therefore, the percentage increase of the product was of 145%.

What is the common ratio of the sequence? -2,6,-18,54

aivan3 [116]

ANSWER

The common ratio is -3.

EXPLANATION

In general, the common ratio of a Geometric Sequence is given by:

$r = \frac{a_{n+1}}{a_{n}}$

We can find the common ratio using any two consecutive terms of the geometric sequence by dividing the subsequent term by the previous term.

The given sequence is -2,6,-18,54

Using the first two terms the common ratio is

$r = \frac{6}{ - 2} = - 3$

We could also used the second and third terms to get

$r = \frac{ - 18}{6} = - 3$

and so on and so forth.

Therefore the common ratio is -3.
