Mathematics

Answer:

see explanation

Step-by-step explanation:

let y = f(x) then rearrange making x the subject

y = 2x - 10 ( add 10 to both sides )

y + 10 = 2x ( divide both sides by 2 )

\frac{y+10}{2} = x

Change y back into terms of x

f^{-1} (x) = \frac{x+10}{2}

Which statement about the values 0.034 and 3.40 are true
Nana76 [90]

Answer:

See Explanation

Step-by-step explanation:

<em>This question requires options.</em>

<em>Since none is provided, I will give a general solution.</em>

<em></em>

We have: 0.034 and 3.40

Required

The relationship between them

3.40 can be expressed as:

3.40 \to 0.034 * 100

This means that 3.40 is 100 of 0.034

Similarly, 0.034 can be expressed as:

0.034 \to 3.40 * \frac{1}{100}

This means that 0.034 is 1/100 of 3.40

do opposites to both sides. what is the opposite of -5? it would be plus 5.

add 5 to both sides

3x = 21

now what is the opposite of 3 times x? 3 divided by.

7nadin3 [17]

The equation representing the given relationship is

y = 0.50x + 15

Given, The cost for renting a car a day is $0.50 per mile, plus a $15 flat fee.

we have to find an equation to represent the given relationship.

Let the number of miles driven be, x

and the total cost be, y

total cost = cost per mile × miles driven + flat fee

Total cost = 0.50 × miles driven + 15

y = 0.50x + 15

Hence, the equation representing the given relationship is

y = 0.50x + 15

Find the missing side length in the image below
Murljashka [212]

Let missing side be x

Using basic proportionality theorem

\\ \sf\longmapsto \dfrac{18}{14}=\dfrac{27}{x}

\\ \sf\longmapsto \dfrac{9}{7}=\dfrac{27}{x}

\\ \sf\longmapsto 9x=7(27)

\\ \sf\longmapsto x=\dfrac{7(27)}{9}

\\ \sf\longmapsto x=21
