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:
The three specific cone cells in our eyes work together, allowing us to translate these three colors of light into millions of different colors. ... When green and blue light are combined, they make cyan. Red and green light make yellow. And when all three primary colors of light are combined, we see white light.
Explanation:
Oxidation numbers play an important role in the systematic nomenclature of chemical compounds. By definition, the oxidation number of an atom is the charge that atom would have if the compound was composed of ions. The oxidation number of simple ions is equal to the charge on the ion. The oxidation number of sodium in the Na+<span> ion is +1.</span>
