Since protons (p*) with a positive charge and neutrons (nº) without a charge are located in the
nucleus, what is the overall charge of the nucleus portion of an atom: positive, negative, or no
charge at all? explain.

A nucleus contains protons and neutrons . Protons are positively charged and neutrons are neutral . So charge of nucleus depends upon protons . Hence , neucleus is positively charged

Explanation:

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
