Find the equation for the line that passes through the point (4,2) that is parallel to the line with the equation

siniylev [52]

Step-by-step explanation:

if they are parralel it means gradient is the same

finding equation we find another point which is (x,y)

therefore y - 2/ x - 4 should be equal to 2/3.

y - 2 = 2/3(x - 4)

y - 2 = 2/3x - 8/3

y = 2/3x - 8/3 + 2

The vertical asymptote of the function f(x) = 3 log(x + 3)

ipn [44]

A function has a vertical asymptote where it is not defined, and the logarithm is defined only if its argument is strictly positive: it has a vertical asymptote if its argument is zero, and is not defined if its argument is negative.

So, you have a vertical asymptote where

$x+3=0 \iff x=-3$

Explain how you can use equivalent fractions to find the quotient of 2 3 ÷ 4.

Virty [35]

Answer:

see below

Step-by-step explanation:

2/3 ÷ 4

We use copy dot flip

The flip means make a reciprocal of the second number

2/3 * 1/4

Multiply the numerators

2*1 = 2

Multiply the denominators

3*4 =12

Put the numerator over the denominator

2/12

Simplify

A book seller gains 30% on the cost price by selling a book for $130.Calculate the cost price of the book.

zlopas [31]

Answer:

Let the cost price be x

Selling price, S.P. = 130
Gain % = 30%

$\rm{C.P. = \dfrac{S.P. \times 100}{100+ gain \% }}$

$\rm{C.P. = \dfrac{130 \times 100}{100+30}}$

$\rm{ C.P. = \dfrac{130}{30} }$

$\large{\boxed{\rm{ C.P. = \dfrac{13}{3}}}}$
