Answer:
The total charge in an atom is zero or it is neutrally charge. both nulify each others charge.
- If the atom has some charge in it then it is called an ion.
Answer:
50%
Step-by-step explanation:
(V2−V1)|V1|×100
=(7.5−5)|5|×100
=2.55×100
=0.5×100
=50%change
=50%increase
Answer:
a) 5
b) 20
c) 28
d) 10
Step-by-step explanation:
a) 7-2=5
b) 2(7)+3(2)
= 14+6
= 20
c) 2(7)(3)= 28
d) (7-2)^2
= (14-4)
= 10
6/24 and 5/16 are the two friends who would have drank 1/4 of the juice.
Answer:
the slope of the line in the graph is: 3
the y-intercept is: -4
the equation of the line is: y=3x-4
Step-by-step explanation:
If we find a point on the graph and count it until it reaches other solid point we get that you have to go up three and to the right by one. This solid point I looked at was (0,-4) and counted up to (-1,1). To find the slope, we have to simply count and use "rise over run". The rise is 3 for every 1 we run, making the slope 3/1 which is 3.
the y-intercept is the point on the graph that touches the y-axis on the graph. The only point on the graph that touches the y-axis is -4, making the y-intercept -4.
The equation for a graph is y=mx+b. m would be the slope and b would be the y-intercept. We know that the slope is 3 (m) and that the y-intercept is -4 (b). Putting them together, we get that the equation of the graph is y=3x-4.
