Answer:
c) y = - 2 x +3
d) y = 1/2 x + 1
Step-by-step explanation:
For c) Look for the exression that contains "3" as the y-intercept (the "b" in the form y = m x + b)
The only equation is y = - 2 x +3
For d) try in all equations if replacing x with 2, gives you an answer "2" for y as well.
The only equation that does such is y = 1/2 x + 1
tn=a+(n-1)d
tn=22+(n-1)4
tn=22+4n-4
tn=4n+18
Answer: its 18.27
3, 15, 14
x + 5x + ( 5x -1) = 32
11x - 1 = 32
11x = 32 + 1
11x = 33
11x/11 = 33/11
x = 3
therefore
the first number is 3
the second is 5 × 3 = 15
the third number is 15 - 1 = 14
3/11
Divide both the numerator and denominator by 2.
