The general form of the equation of a circle is,
x² + y² + Dx + Ey + F = 0, where D, E, F are constants.
The given equation is 7x² + 7y² − 28x + 42y − 35 = 0. So, to convert this equation into a general form we just need to get rid of the leading coefficient 7.
Hence, divide both sides of the equation by 7. So,
x² + y² − 4x + 6y − 5=0.
So, the general form of the equation is x² + y² − 4x + 6y − 5=0.
Answer:
1:26.25
Step-by-step explanation:
Scale = 16 in:35 ft
Convert 35 ft to inches
1 ft = 12 in
35 × 12/1 = 420 in
Scale = 16 in:420 in Divide each term by 16
Scale = 1:26.25
5 object which are longer than your hand- span in my surrounding is Note book, Laptop, Window, Curtain, Table.
Hand span is a measure of distance from the tip of the thumb to the tip of the little finger with the hand fully extended.
Hand span is a measure that has been used for many years. By placing the hand on the edge of a piece of paper and marking the tips of the thumb and little finger, the student can measure a straight line. This is a better method than placing the hand directly on the ruler.
Hand span and cubit are not used as standard units of length because their sizes vary from person to person. So, two different persons may give different measurements for the same length, which is not desirable for a standard unit.
Measure using yours hands and write as per your hand-span measurement.
Therefore,

Answer:
1
Step-by-step explanation:
7 + 2x = 9
Carry over the 7 to the 9.
2x = 9-7
2x= 2
x = 2÷2
x = 1
