If you had 4 quarters and 8 nickels how much money would you have?

spin [16.1K]

Answer and Step-by-step explanation:

A Quarter is equal to 25 cents.

A Nickel is equal to 5 cents.

We have 4 quarters and 8 nickels, so times this amount of coins to their values.

4 × 25 = 100

8 × 5 = 40

Now, we add these together.

140.

This is 140 cents.

After the 100 mark, it turns into a dollar (because there is 100 pennies (cents) in 1 dollar).

So that means the total amount of money we have is One dollar and Forty cents ($1.40)

Write the equation that passes through the following points: (5,0) and (−10,−5)

Vikentia [17]

Answer:

The answer is:

$y = \frac{1}{3} x - \frac{5}{3}$

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

$y = mx + b$

❃Incase you also forgot, The is what the slope formula is ☟

$m = \frac{y_2 - y_1 }{x_2 - x_1}$

➊ First: We are going to be solving for the slope.

$m = \frac{ - 5 - 0}{ - 10 - 5} = \frac{ - 5}{ - 15} = \frac{1}{3}$

➋Second: We find the y-intercept.

$y = mx + b \\ 0 = \frac{1}{3} (5) + b \\ 0 = \frac{5}{3} + b \\ \frac{ - \frac{5}{3} = - \frac{5}{3 } \: \: \: \: \: \: \: \: \: \: \: \: }{ - \frac{5}{3} = b}$

➌Third: Plug in.

$y = \frac{1}{3} x - \frac{5}{3}$
