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%
