Answer:

Increasing by 40%

Step-by-step explanation:

This is a exponentional function. The format for this type of function is a(b)^x. So "a" is your initial value, and "b" is the rate. Now let's think to ourselves what times what is still equal to the same thing? That is 1. But in our question, we have 1.4. So we are increasing by 0.4, or 40%.

What are the steps to this equation

Harlamova29_29 [7]

Answer:

$x=7$

Step-by-step explanation:

$\frac{2}{5}x+\frac{1}{3}=\frac{1}{3}x+\frac{4}{5}$

Subtract $\frac{1}{3}$ from both sides:

$\frac{2}{5}x+\frac{1}{3}-\frac{1}{3}=\frac{1}{3}x+\frac{4}{5}-\frac{1}{3}$

$\frac{2}{5} x=\frac{1}{3}x+\frac{12}{15}-\frac{5}{15}$

$\frac{2}{5}x=\frac{1}{3}x+\frac{7}{15}$

Subtract $\frac{1}{3} x$ from both sides:

$\frac{2}{5}x-\frac{1}{3}x=\frac{1}{3}x+\frac{7}{15}-\frac{1}{3}x$

$\frac{6}{15}x-\frac{5}{15}x=\frac{7}{15}$

$\frac{1}{15}x=\frac{7}{15}$

Multiply both sides by 15:

$15\times \frac{1}{15}x=\frac{7\times 15}{15}$

$x=\frac{105}{15}$

$x=7$

Factor 3/4 out of 3/4z + 6

Alenkasestr [34]

ANSWER

$\frac{3}{4} z + 6 = \frac{3}{4} (z + 8 )$

EXPLANATION

We want to factor
$\frac{3}{4}$
out of

$\frac{3}{4} z + 6$

The first term is already having a factor of
$\frac{3}{4}$
The constant term which is the second term is not having a factor of
$\frac{3}{4}$
so we need to use a trick of multiplying and dividing by the same factor to obtain,

$\frac{3}{4} z + 6 = \frac{3}{4} z + \frac{3}{4} \times \frac{6}{ \frac{3}{4} }$

We can now factor
$\frac{3}{4}$
out of the right hand side to obtain,

$\frac{3}{4} z + 6 = \frac{3}{4} (z + \frac{6}{ \frac{3}{4} } )$
Let us rewrite the right most fraction using the normal division symbol.

$\frac{3}{4} z + 6 = \frac{3}{4} (z + 6 \div \frac{3}{4} )$

We simplify to obtain,

$\frac{3}{4} z + 6 = \frac{3}{4} (z + 6 \times \frac{4}{3} )$

This further gives us,

$\frac{3}{4} z + 6 = \frac{3}{4} (z + 2 \times 4 )$

$\frac{3}{4} z + 6 = \frac{3}{4} (z + 8 )$
