Convert the rectangular coordinates (11,-4) to polar coordinates. a. (11.7, -20)
c. (10.2, -20)
b. (11.7, 70)
d. (10.2, 70)  
Please select the best answer from the choices provided​

answer: #1 ads up by 8 and i don't know #2

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

is it like a multiple choice? if so then i need the multiple choice so i can get and understanding on what the answers is so that i can explain it to you
