What’s the slope and y intercept of y=2x-4

2/1 and -4

Step-by-step explanation:

All equations in slope-intercept form are written in y = mx + b format, where m is the slope and b is the y-intercept.

Here, the m is 2 and the b is -4. Note: it's not positive 4 because of the negative sign in front of it.

Therefore, the slope is 2/1 (or simply, 2) and the y-intercept is (0,-4), or just -4.

df =

both have same length

(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
