Answer:
the answer is 4y-2
Step-by-step explanation:
To simplify any algebraic expression you need to add liketerms.
In this equation, the liketerms are y and 3y.
3y+y= 4y
We are left with 4y-2; we cant go any further, because 4y and -2 are not liketerms.
Input is 4
so y=-2(4)+11
y=-8+11
y=11-8
y=3
Ans
(4,3)
So the function is

the intial value is where x=0
where x=0, the value of f(0)=3
grouth is 1/3 but it is decay, so it might be correct, or not because it is decay
it is exponential decay
true it is a stretch of the funciton f(x)=(1/3)^x
when x=3, then f(3)=1/9
the true things are
The function shows exponential decay.
The function is a stretch of the function f(x) = (1/3)x .
Answer:
3
Step-by-step explanation:
AB = 1 unit
A'B' = 3 units
The scale of dilation = A'B'/AB
Therefore:
scale of dilation = 3 units / 1 unit = 3
This means that ABC was dilated or enlarged in size by multiplying every of its segment by 3. In essence, A'B'C' is 3 times the size of ABC.
Answer:
48
Step-by-step explanation:
3 times 13 (john's age) = 39
39 + 9 = 48 (nine years older than 3 times (39) so you add 9)
Therefore, Tim is 48.
