Answer:
#5 x=8, #6 x=5
Step-by-step explanation:
Theyre vertical so for number 5 you would have the equation
5x+15=55
-15 -15 from both sides
5x=40
divide by 5 from both sides and you get
x=8
Same thing vertical so you would have
16x+7=87
-7 -7 from both sides
16x=80
divide by 16 from both sides
x=5
Answer: f(f(f(x)))=8x-7
Step-by-step explanation:
Since we were given f(x) and f(f(x)), We plug that into f(x) again to get f(f(f(x))).
2(4x-3)-1 [distribute]
8x-6-1 [combine like terms]
8x-7
Answer:
No
Step-by-step explanation:
plug (6,3) into the given equation to find out
3 = 4(6-5)
3 = 4(1)
3 = 4
since 3 does not equal 4, the point (6,3) does not satisfy the equation y=4(x-5)
PART A:
x | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
y | 6 | 5.5 | 5 | 4.5 | 4 | 3.5 | 3 | 2.5 | 2 | 1.5 | 1 | 0.5 | 0 |
x=hours
y=candle length
PART B:
Yes it is a function because you can input the values
PART C:
Yes, it will still be a function but with a different different y value
Answer:
The estimated percentages i could think of were 2/9, 1/3, 23/90, 20/90
Step-by-step explanation:
estimates include rounding. So i rounded to the nearest fractions and picked out the best ones.
