Solve each equation by graphing the related function. if the equation has no real-number solution, write no solution . 1: x^2+ 7=0 2: 3x^2=0 3: 1/4x^2 - 4=0 4: 4g^2=25

See each answer below.

1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.

2) Dividing by 3 and taking the square root gives an answer of 0.

3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.

4)  Divide by 4 and then take the square root. You have positive or negative 5/2.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
