y = -5x + 22 is the equation of our parallel line

Step-by-step explanation:

remember a parallel line will have the same slope.

So let's begin by using the equation above and substituting the points.

[tex]y = - 5x + b \\ - 8 = - 5(6) + b \\ - 8 = - 30 + b \\ 30 - 8 = b \\ b = 22[/tex]

Given f(x) = x^2 – 5x + k, and the remainder when f(x) is
divided by x - 7 is 34, then what is the value of k?

Answers

Step-by-step explanation:

f(7) = 34

7² -5(7) +k = 34

49-35+k =34

14+k = 34

k = 34-14

k = 20

>> Answer

__________

[tex] \: [/tex]

f(x) = x² - 5x + k

f(7) = 34

Soo :

f(7) = 34

(7)² - 5(7) + k = 34

49 - 35 + k = 34

14 + k = 34

k = 34 - 14

k = 20

Today only, a desk is being sold at a 33% discount. The sale price is $603.
What was the price yesterday?

Answers

The original price of the desk before discount was $900.

What is discount?

A discount is the reduction in the marked price of items, discounts are generally given to customers to attract them towards some items or on sale.

Given that a desk is at sell today, the shop is offering 33% discount on it, which will give a selling price of $603.

We need to find the desk's yesterday price,

So, let the yesterday price be x,

Therefore,

100 - 33 = 67

Therefore,

67% of x = 603

x = 603 × 100 / 67

x = 900

Hence the original price of the desk before discount was $900.
