Answer:
The value of 'x' is 1 and 'y' is 2. So, the point is (1, 2).
Step-by-step explanation:
Given:
The given pair of linear equations are:

In order to solve by elimination method, we have to eliminate any one variable using mathematical operations. Let us eliminate 'y'.
Multiplying the first equation by 2 and adding the result to the second equation. This gives,

Now, the value of 'y' can be calculated by plugging in 1 for 'x' in the first equation. This gives,

Therefore, the value of 'x' is 1 and 'y' is 2.
The solution is (1, 2).
assuming the scale is by 1,
a) the slope is rise/run so it rises 3 units and moves 4 units right therefore the slope is 3/4
b) the y intercept is where the line crosses the y axis so by looking at the graph you can tell that the y int is 1
c) and the equation is made up of the slope and the y intercept: y= 3/4x + 1
Answer:
The surface area of a sphere of radius r is 4 π r2. Half of this is 2 π r2. If this is what is meant by the surface area of a hemisphere then 2 π r2 = 1062.
