Answer:
-15
Step-by-step explanation:
The equivalent expression for the given expression is 8x+20.
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
The given expression is 4(2x+5).
The given expression can be simplified as follows
4×2x+4×5
= 8x+20
Therefore, the equivalent expression for the given expression is 8x+20.

Step-by-step explanation:
A statistical question is one that can be answered by collecting data and where there will be variability in that data.
Answer:
When x=0, y=4...
Therefore:
4=a*b⁰
b⁰=1, so a=4.
----------
When x=1, y=2...
Therefore:
2=4*b¹
4b=2
b=2/4
So... b=1/2.
This means that:
y=4*((1/2)^x)
