Use your grapher to determine which of the graphs matches the polar equation r = 1 + 2 cos θ. a circular graph with an inner loop on the left a circle tangent to the y-axis, symmetric about the axis, and lying in quadrants one and four a circular graph with an indentation on the left to the origin a graph of four loops originating at the origin lying on and symmetric about the and y-axes This is not multiple choice so please explain your answer... I need help FAST but I need reliable answers pleaseee! :)

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

entering that problem on the tube might get you an answer

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
