Answer:
POINTS OF INTERSECTION ARE:
x = -1
y = 3
coordinates : (-1,3)
Coordinates :
Explanation:
Condition for intersecting lines
here
a1 ,a2 = coefficients of x (a1 = -1 , a2 = 6)
b1 ,b2 = coefficients of y(b1 = 1 , b2 = 1)
Calculation :
Here substitution method is used : Value of y from eq (1) is substitued in equation (2)
-x + y = 4
y = 4 + x.............(i)
put value of x in equation (2)
6x + y = -3
6x + 4 + x = -3 ( from i)
7x = -3 - 4
7x = -7
x = 
x = -1
using equation(i)
y = 4 + (-1)
y = 4 - 1
y = 3
Check:
The values of x and y should satisfy equation (1) and (2)
for equation 1
-x+y =4
= -(-1) + 3
= 1 + 3
= 4
Hence coordinates satisfy equation 1
Answer:
Mg
Explanation:
If one were comparing just the neutral atoms Mg and S, the S atom would be smaller as both elements are in the same period and sulfur is more to the right
Hihi!
The correct answer is B. The mass number of this nuclide is 131! It's proton number is 56 and it has 75 neutrons (131 - 56 = 75 neutrons).
I hope I helped!
