Step-by-step explanation:
1)The given equations are:
x − 2y = 6 ...(i)
3x − 6y = 0 ...(ii)
Putting x = 0 in equation (i) we get
=> 0 - 2y = 6
=> y = -3
x = 0, y = -3
Putting y = 0 in equation (i) we get
⇒x-2×0=6
⇒x=6
x = 6, y = 0
Use the following table to draw the graph
x 0 6
y -3 0
Plotting the two points A(0, -3) and B(6,0) equaion (1) can be drawn
Graph of the equation ..(ii)
3x - 6y = 0 ...(ii)
Putting x = 0 in equation (ii) we get
⇒3×0-6y=0
=> y = 0
x = 0, y = 0
Putting x = 2 in equation (2) we get
⇒3×2-6y=0
=> y = 1
x = 2, y = 1
Use the following table to draw the graph.
x 0 2
y 0 1
Draw the graph by plotting the two points O(0,0) and D(2,1) from table
We see that the two lines are parallel, so they won’t intersect
Hence there is no solution
2)
Answer:
given a quadratic function, y = ax2 + bx + c, when "a" is positive, the parabola opens upward and the vertex is the minimum value. On the other hand, if "a" is negative, the graph opens downward and the vertex is the maximum value
Step-by-step explanation:
10. If it rained 7/10 of the days, 3/10 days did not receive rain.
90 days multiplied by 3/10 is 27.
It would not rain about 27 days in the 90 days.
11. x multiplied by 8 and a half equals 5.
(8 and 1/2)x = 5
x = .588235 which is about 6/10
12. C = 6/10 and D = 8/10 so the product would be 48/100 which is close to 5/10. This point is N.
Answer:
93.79
Step-by-step explanation:
22.00 + 21.33 = 43.33
22.95 + 27.51 = 50.46
43.33 + 50.46 = 93.79
