40 weeks because you divide 500 by 4 which is 125 then you guess and check to make 40 multiplied by 125 is 5,000
Answer:
No cheating: you’re starring in a movie w/ the last person saved in your camera roll and the last song you listened to is the title.
"let's go everywhere" the movie with taemin and taeyong sounds like something i would watch ♡ https://t.co/tGdUt7CKPc
Lets check all the choices:
A. subtraction:
(3x+2)-(4y-11)=3x+2-4y+11=3x-4y+13
similarly, (4y-11)-(3x+2)=-3x+4y-13
both are polynomials (of 2 variables)
B. (3x+2)(4y-11)=12xy-33x+8y-22, which is a polynomial
C. (3x+2)+(4y-11)=3x+2+4y-11=3x+4y-9, which is a polynomial
D.
both
and
are rational expressions in 2 variables, not polynomials
Answer: D
Answer:
Step-by-step explanation:
if r=1 perfect positive correlation.
if r=-1 ,perfect negative correlation.
r=0 ,no correlation.
r=.02 ,so D
Answer:
solution given a-d ,a, a+d, a+2d are in A.P
according to the question
sum of 4 terms =12
a-d+a+a+d+a+2d=12
4a+2d=12
2a+d=12/2
d=6-2a
again
3rd + 4rt term =14
a+d+a+2d=14
2a+3d=14
substituting value of d
2a+3(6-2a)=14
2a+18-6a=14
18-14=4a
a=4/4=1
again
d=6-2×1=4
first term =a-d=1-4=-3
second term =a=1
third term =a+d=1+3=4
forth term =a+2d=1+3×2=7
