Answer:
x = 10 - 2y
Step-by-step explanation:
The question is telling you to express x in terms of y. Essentially, you solve the given equation(s) for x.
x can be found from the first equation by subtracting 2y from both sides:
x = 10 - 2y
_____
When there are infinitely many solutions, either x or y can be arbitrarily chosen, and the appropriate value computed for the other variable.
Here, the answer is telling you "type an expression using y as the variable as needed." That is, y is selected to be the variable arbitrarily chosen, and we need an expression that will tell us the corresponding value of x. The appropriate expression is found by rearranging the equation(s) to "make x the subject". (I call that process "solve the equation for x.")
<span>The area to be determined is a segment of the circle.
Since central angle is 120 degrees and 120/360 = 1/3
area of sector of circle is (1/3)*36pi = 12pi
For the area of triangle, you can split it into 2 30-60-90 right triangles with sides 3:3sqrt3:6
thus base of triangle is 6sqrt3 and height is 3
Area = 1/2 * 3* 6sqrt3 = 9sqrt3 -->
segment area = 12pi - 9sqrt3</span>
Answer:
x = -9
Step-by-step explanation:
subtract 3 from both sides
x = -9
