Let E represent English test and M represent Math test.
M + E = 164
+ <u>M - E = 22</u>
2M = 186 <em>eliminated E by adding the two equations</em>
M = 93 <em>divided both sides by 2</em>
Now, plug that value into either of the equations to solve for E.
M - E = 22 → 93 - E = 22 → -E = 22 - 93 → -E = -71 → E = 71
Answer: Math = 93, English = 71
Answer:
Step-by-step explanation:
The given equations are:
and 
On solving
, we get the graph which is red in colour.
By Putting x=o in the equation⇒y=3
Putting x=-3⇒y=4
Now, plotting the graph for the equation
, it is plotted as blue colour by putting x=0⇒y=-4 and by putting x=3⇒y=2, Following the same path, we can plot the two graphs for the given equations.
Answer:
point "i" has coordinates (-x, y)
Step-by-step explanation:
Any point on the horizontal line containing point A will have the same y-coordinate. It appears that point "i" in the diagram is a point on the circle and on the horizontal line, so is the point you're looking for. Because the circle is centered at the origin, point "i" will have an x-coordinate that is the opposite of that of point A.
Point "i" is such a point. It has coordinates (-x, y).
Its Easy U just had to break it down.
Option-D=21 is correct.
