Answer:
See below in bold.
Step-by-step explanation:
The 50 grams of alloy contains 50 * 0.52 = 26 g of pure copper.
So the amount of copper n the mixture = 78 + 26 = 104 g.
The total mass of the mixture = 78 + 50 = 128 g.
% copper = 104 * 100 / 128
= 81.25%.

Step-by-step explanation:
It can be classified as a rational number because it can be in the form of p/q as of fraction and is made up of two integers making p the numerator and for q a denominator not involving a zero.
Answer:
y = -1/2x - 2
Step-by-step explanation:
If it's parallel, that means that the slope is the opposite of the one in the given equation, meaning that 2 would be flipped and turned negative into -1/2.
Then, fill in the x and y values to get the y-intercept.
1 = -1/2(-6) + b
1 = 3 + b
-2 = b
So your answer is y = -1/2x - 2
