Hello :
x : length y :<span> width
</span>xy = 50 ...(1)
x = 2y ...(2)
dubsct in (1) :
(2y)(y) = 50
y² = 25
y = 5
x = 10
Answer:
2x^2+7
Step-by-step explanation:
Let x=5
2x^2+7
2 ( 5)^2 +7 = 2*25 +7 = 50+7 = 57
(x^3-5)/3
(5^3 -5)/3 = (125-5)/3 = 120/3 = 40
(10x -2)/ (x-3)
(10*5-2)/(5-3) = (50-2)/(2) = 48/2 = 24

Answer:
f(-2)=-9
Step-by-step explanation:
3*-2=-6. -6-3=-9.
Notice that:
7=16-9
2=9-7
5=7-2
the next term would be: 2-5=-3
so each term of the sequence is equal to its previous term, subtracted from the second previous term:
Also, in order to describe the formula, we need to express the 2 first terms, 1 is not enough.
The recursive formula is:
