Answer:
Step-by-step explanation:
Charge on atom is due to electron
Electron have negative charge while proton have positive charge and neutron have no charge. If there are 10 proton (10 positive charge)
Answer:
y-intercept: (0, 12/5) or (0, 2.4)
x-intercept: (12/7, 0) or (1.714, 0)
Step-by-step explanation:
The y-intercept is the point where the graph crosses the y-axis. That means, the point (0, yi). To find yi, we have to substitute x by 0 in the equation.
7x + 5y=12
7*0 + 5y = 12
y = 12/5 = 2.4
y-intercept: (0, 12/5) or (0, 2.4)
The x-intercept is the point where the graph crosses the x-axis. That means, the point (xi, 0). To find xi, we have to substitute y by 0 in the equation.
7x + 5y=12
7x + 5*0 = 12
x = 12/7 = 1.714
x-intercept: (12/7, 0) or (1.714, 0)
Finally, the graph is shown below.

I used the rule a^b*a^c = a^(b+c) on the third step.
Answer:
2 1/10
Steps:
You need both fractions to have the same denominator, you get 6/10 and 5/10
Subtract your fraction:
6/10 - 5/10 = 1/10
Then your whole numbers:
3 - 1 = 2
Then put your answers together:
2 1/10
Knowing that the area of a square is equivalent the square of its side length, the length of one side can be calculated by taking the square root of the area. The square root of the expression 9q^4r^8s^8 units is equivalent to <span>3q2r4|s3| units. When taking the square root of variables, the power they are raised to is divided by 2.</span>
