Writing to Learn x- and y-intercepts

riadik2000 [5.3K]

The x and y intercepts of a line are when $y=0$ and $x=0$ respectively.

c and d are the x and y intercepts because they represent C/A and B/A in the standard linear equation

The x and the y intercepts are related to c and d because they represent the values of the equation when y and x equals 0 respectively.

The given equation is:

$\frac xc + \frac yd = 1$

<u>(1) Why c and d are the intercepts</u>

We have:

$\frac xc + \frac yd = 1$

Multiply through by cd

$cd \times \frac xc + cd \times \frac yd = cd \times1$

$dx + cy = cd$

A linear equation is represented as:

$Ax + By = C$

Where:

$\frac CA \to$ x intercept

$\frac BA \to$ y intercept

So, by comparing $Ax + By = C$ to $dx + cy = cd$

$\frac CA \to d \to$ The x-intercept

$\frac CB \to c \to$ The y-intercept

<u>(b) How the intercepts are related to c and d?</u>

In (a) above, we have:

$\frac CA \to d \to$ The x-intercept

$\frac CB \to c \to$ The y-intercept

When $x = 0$

We have:

$dx + cy = cd$

$d \times 0 + cy = cd$

$cy = cd$

Divide by c

$y = d$ ---- the y-intercept

When $y = 0$

We have:

$dx + cy = cd$

$dx + c \times 0 = cd$

$dx = cd$

Divide by d

$x =d$ ---- the x-intercept

Elise says, "If you subtract 16 from my number and multiply the difference by - 7, the result is

e-lub [12.9K]

Answer:

-6

Explanation:

Elise's number is x.

If you subtract 16 from her number -> x-16

and multiply the difference by 7 -> 7(x-16) = -154

Elise's number is -154/7+16 = -6

Answer:

Jeannette's ticket was less than the original pice by 30%

Step-by-step explanation:

original price = $75

percentage discount = 20% of original price = 20% of $75

discounted price = $\frac{20}{100} \times\ 75\ =\ 15$

discounted price = $15

website service fee = 10% of original price

website service fee = $\frac{10}{100}\times 75 = \$7.5$

New discounted price = discount price + website service fee

= 15 + 7.5 = $22.5

Next, let us calculate what percentage of the original price that will give the new discount price.

Let the percentage of the original price = x%

x% of 75 = $22.5

$\frac{x}{100} \times\ 75\ = 22.5\\\\\frac{75x}{100} = 22.5\\\\75x = 2250\\\\x = \frac{2250}{75} \\\\x = 30$

Therefore, Jeannette's ticket was less than the original pice by 30%
