Can you answer 19 and 20 if you can??? thank u

19) A 20) C

Step-by-step explanation:

19. since the lines are parallel, the line will have the same slope. Then you can just plug in the coordinates to find the rest of the equation, so you get y=-2x+6.

20. Perpendicular lines have slopes that are the opposite reciprocals of each other. Since the slope was 1/5, the slope of the perpendicular line would be -5. Now you can plug the coordinates into the equation to solve for b, and you would get y=-5x+12

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
