Answer:
Copper is being reduced
Step-by-step explanation:
Since the charge of the copper ion went down (2+ --> 0), we can say that Copper is being reduced. An atom is reduced when electrons are added.
100 - 20 = 80
179.00 = 80%
179.00 / 80 = 2.2375 = 1%
1% x 100 = 100%
So, 2.2375 x 100 = 100%
Therefore the original price was 223.75
Answer:
y = 2x
linear equations are just finding the right ratio and putting it in y = mx+b format
this graph is saying that two dollars are earned for every ticket sold, a 2:1 ratio.
so the equation would be y = 2x, two being the amount of money collected for one ticket, and x being the number of tickets sold.
answer:
the answer is -3 and 8
Step-by-step explanation:
we will place -3 in the equation
(x+3)(x-x)=0
(-3+3)=0 (because -3+3 will cut down together)
we will place two 8(eights) in the equation
(8-8)=0
final answer is
(0)(0)=0
so -3 and 8 fits well in the equation
You can simply expand the factorised form out:
y = 14x² - 21x + 10x - 15
y = 14x² -11x -15
