Answer:
To show that a conjecture is false, you have to find only one example in which the conjecture is not true. So an example could be a drawing, a statement, or a number.
Answer:
(x , 1/2x - 5/2) where x is a real number.
Step-by-step explanation:
-2x + 4y = -10 ⇔ 4y = 2x - 10 ⇔ y = 1/2x - 5/2
then any couple of the form (x , 1/2x - 5/2) is a solution to the equation
example :
let x = 7 then 1/2x - 5/2 = 1/2(7) - 5/2 = 1
in this case -2x + 4y = -2(7) + 4(1) = -14 + 4 = -10
then (7,1) verify the equation
Answer:
$27.17
Step-by-step explanation:
Regular price of necklace = $44
If a discount of 35% is applied, then the new price of the necklace will be 65% of the regular price, as 100% - 35% = 65%
⇒ 65% of $44
= 0.65 × $44
= $28.60
If a second discount of 5% is then applied, the final price of the necklace will be 95% of the sale price, as 100% - 5% = 95%
⇒ 95% of $28.60
= 0.95 × $28.60
= $27.17
Therefore:
The sale price with a 35% discount is $28.60
The sale price with an additional 5% discount is $27.17
