Answer:

x =  - 3 \frac{4}{15}

Step-by-step explanation:

2x -  \frac{1}{3}  + 3  = x -  \frac{3}{5}

=  > 2x -  \frac{  1 +9 }{3}  = x -  \frac{3}{5}

=  > 2x +  \frac{8}{3}  = x -  \frac{3}{5}

=  > 2x - x  =  -  \frac{3}{5}  -  \frac{8}{3}

=  > x =  -  \frac{9 - 40}{15}

=  > x =  -  \frac{49}{15}

=  > x =  - 3 \frac{4}{15} (ans)

Answer:

x = - \frac{49}{15}

Step-by-step explanation:

Given

2x - \frac{1}{3} + 3 = x - \frac{3}{5}

Multiply through by 15 ( the LCM of 3 and 5 ) to clear the fractions

30x - 5 + 45 = 15x - 9 , that is

30x + 40 = 15x - 9 ( subtract 15x from both sides )

15x + 40 = - 9 ( subtract 40 from both sides )

15x = - 49 ( divide both sides by 15 )

x = - \frac{49}{15}

Find all numbers between 200 and 500 which have exactly 9 factors
MakcuM [25]

Answer:

225, 256, 441, 484

Step-by-step explanation:

Only square numbers can have an odd number of factors, e.g. 4: 1, 2, 4

Therefore only square numbers can have 9 factors.

There are only 8 square numbers between 200 and 500: 225, 256, 289, 324, 361, 400, 441, 484.

One way is to list all the factors of each number and you will find that only 225, 256, 441 and 484 have 9 factors.

The other more efficient way is to acknowledge the fact that if a square number (n x n) has 9 factors, n must have only 4 factors. For example, 225 has 9 factors because it is equal to 15 squared and 15 only has 4 factors: 1, 3, 5, 15.

This way, we can find out that 15, 21 and 22 have exactly 9 factors. However, 256 has 9 factors as well as it is equivalent to 2 to the power of 8. This means that it already has 8 factors: 2, 4, 8, 16...,128, 156. However, we must include 1 as a factor which means it has 9 factors in total as well.

What is the effect of k on f(x)=g(5x) where g(x) is a piecewise function? Explain.
Crazy boy [7]

Answer:

g(x) will be dilated horizontally to get f(x)

Step-by-step explanation:

Given

f(x) = g(kx) --> the correct equation

Required

The effect of k

The given equation is an illustration of horizontal dilation.

If |k| is greater than 0, then the function will be compressed.

However, if |k| is between 0 and 1 (exclusive), then the function will be stretched.

Take for instance:

f(x) = g(x/5)

In the above function, g(x) will be stretched by 5 units

Another instance is:

f(x) = g(x/0.5)

In the above function, g(x) will be stretched by 0.5 units
