A, B, D are functions.
(First, second, and fourth response)
You can see which is function since for everyone input only has one value. You can also use the vertical line test.
Answer:x=8
Step-by-step explanation:
3×4 = 12 so 2×4 = 8
Part A:Bees: f ( t ) = 1,500 * 0.88^tFlowering plants: g ( t ) = 800 - 25 tPart B :f ( 6 ) = 1,500 * 0.88^6 = 696.6 ≈ 697
g ( 6 ) = 800 - 25 * 6 = 800 - 150 = 650Part C :f ( 7 ) = 1,500 * 0.88^7 = 613g ( 7 ) = 800 - 7 * 25 = 625f ( 7 ) ≈ g ( 7 )After approximately 7 months.
Answer:
y = 2/5 x - 3/5
Step-by-step explanation:
2x = 5y + 3
Rewrite
5y + 3 = 2x
Subtract 3 from both sides
5y = 2x - 3
Divide both sides by 5
y = 2/5 x - 3/5
