Graph the linear equation. Find three points that solve the equation, then plot on the graph. PLEASE HELP!!!
1 answer:
For a better understanding of the solution provided here please find the three files that have been attached.
We are given the equation
This equation can be simplified to represent in terms of
as:
To find three points that solve the equation, all that we need to do is to choose three convenient values of and solve the corresponding
values. For this, we will make a table which has been attached as the first file.
As can be seen from the table, the three points that lie on the graph or in other words solve the equation are: .
On a graph, mark these three points as shown on the graph in attachment 2.
Now, as a final step take a scale ruler and draw a straight line joining all the above three points. The resulting line will be the graph of the linear equation, -3x + 2y = 2.
The last attachment shows the final graph.

Answer:
The angle it turns through if it sweeps an area of 48 cm² is 448.8°
Step-by-step explanation:
If the length of a minute hand of a clock is 3.5cm, to find the angle it turns through if it sweeps an area of 48 cm, we will follow the steps below;
area of a sector = Ф/360 × πr²
where Ф is the angle, r is the radius π is a constant
from the question given, the length of the minute hand is 3.5 cm, this implies that radius r = 3.5
Ф =? area of the sector= 48 cm² π =
we can now go ahead to substitute the values into the formula and solve Ф
area of a sector = Ф/360 × πr²
48 = Ф/360 × × (3.5)²
48 = Ф/360 × ×12.25
48 = 269.5Ф / 2520
multiply both-side of the equation by 2520
48×2520 = 269.5Ф
120960 = 269.5Ф
divide both-side of the equation by 269.5
448.8≈Ф
Ф = 448.8°
The angle it turns through if it sweeps an area of 48 cm² is 448.8°
