Slope of 1,-7 and -3-4

3241004551 [841]

$\large \mathfrak{Solution : }$

Slope of the given line is :

$\dfrac{y_2 - y_1}{x_2 - x_1}$

where ,

$x_2 = 1$

$x_1 = - 3$

$y_2 = - 7$

$y_1 = - 4$

let's solve :

$\dfrac{ - 7 - ( - 4)}{1 - ( - 3)}$

$\dfrac{ - 3}{4}$

Slope = -3 / 4

Bill found a book he wanted on sale for $20.80. The original price of the book was $32. Find the discount rate.

Maurinko [17]

Answer:

35% discount

Step-by-step explanation:

We can first find what percent of 32 20.80 is.

This can be shown by using a percent proportion.

$\frac{20.80}{32} = \frac{x}{100}$

We can cross multiply to find the value of $x$ .

$20.80\cdot100=2080\\\\2080\div 32 = 65$

So 20.80 is 65% of 32.

However, this is the percent of the original price. To find the discount, we have to subtract 65 from 100.

$100 - 65 = 35$

So the book was on a 35% discount.

Hope this helped!

4/3y=48<br><br>solve for y<br><br>simplify answer as much as posible

Helga [31]

<h2>If you mean :</h2>

$\frac{4}{3y} = 48 \\$

Inverse both sides

$\frac{3y}{4} = \frac{1}{48} \\$

Multiply both sides by 4

$4 \times \frac{3y}{4} = 4 \times \frac{1}{48} \\$

$3y = \frac{4}{48} \\$

$3y = \frac{4 \times 1}{4 \times 12} \\$

$3y = \frac{1}{12} \\$

Divide both sides by 3

$3y \div 3 = \frac{1}{12} \div 3 \\$

$y = \frac{1}{12} \times \frac{1}{3} \\$

$y = \frac{1}{36} \\$

_____________________________________________

<h2>If u mean : </h2>

$\frac{4}{3} y = 48 \\$

Multiply both sides by the 3

$3 \times \frac{4}{3} y = 3 \times 48 \\$

$4y = 3 \times 48$

Divide both sides by 4

$4y \div 4 = 3 \times 48 \div 4$

$y = \frac{48 \times 3}{4} \\$

$y = \frac{4 \times 12 \times 3}{4 \times 1} \\$

$y = 12 \times 3$

$y = 36$
