Answer:
1. no. 2.no
Step-by-step explanation:
1.
= (5\3) × (1/1-x)
but 8-8x = 8(1-x)
2. 2(6-3x) = 12-6x =6(2-x)
2(3x) + x= 6x +x = 7x

Answer:
Step-by-step explanation:
<u>Equation of a circle</u>
where:
- (a, b) is the center
- r is the radius
From inspection of the diagram, the center of the circle <em>appears</em> to be at point (-3, 2), although this is not very clear. Therefore, a = -3 and b = 2.
Substitute these values into the general form of the equation of a circle:
Again, from inspection of the diagram, the <u>maximum vertical point</u> of the circle appears to be at y = 5. Therefore, to calculate the radius, subtract the y-value of the center point from the y-value of the maximum vertical point:
⇒ radius (r) = 5 - 2 = 3
Substitute the found value of r into the equation:
Therefore, the final equation of the given circle is:
