Two different questions.. please try to answer both if possible!!!
boyakko [2]

Answer: A

<u>Step-by-step explanation:</u>

f(x) = -5x - 4   ⇒   y = -5x - 4     <em>switch the x's and y's and solve for y</em>

  x = -5y - 4

<u>+4 </u>     <u>      +4 </u>

x + 4 = -5y

\frac{x+4}{-5} = \frac{-5y}{-5}

-\frac{x+4}{5} = y

\frac{-x-4}{5} = y

\frac{-1}{5}x - \frac{4}{5}  = y

***********************************************************

The top line of the second question is cut off so cannot help you without knowing what the restriction is on v(x).

The cost of a circular table is directly proportional to the square of the radius. A circular table with a radius of 50cm costs
Lana71 [14]

Answer:

£135 is the correct answer.

Step-by-step explanation:

Let C be the cost of table.

And let R be the radius of table.

Cost of table is directly proportional to square of radius.

As per question statement:

C\propto R^{2} or

C=a\times R^2  ....... (1)

where a is the constant to remove the \propto sign.

It is given that

C_1 = £60 and R_1 = 50\ cm

C_2 = ? when R_2= 75\ cm

Putting the values of C_1 and R_1 in equation (1):

60=a \times 50^2  ....... (2)

Putting the values of C_2 and R_2 in equation (1):

C_2=a \times 75^2  ....... (3)

Dividing equation (2) by (3):

\dfrac{60}{C_2}= \dfrac{a \times 50^2}{a \times 75^2}\\\Rightarrow \dfrac{60}{C_2}= \dfrac{50^2}{75^2}\\\Rightarrow \dfrac{60}{C_2}= \dfrac{2^2}{3^2}\\\Rightarrow \dfrac{60}{C_2}= \dfrac{4}{9}\\\Rightarrow C_2 = 15 \times 9 \\\Rightarrow C_2 = 135

So, <em>£135 is the correct answer</em>.
