Answer:
#1. 5x - 24
#2. 10x - 1
#3. 10x -14
#4. 6x - 12
#5. 3x63 + 5x^2 - 3
#6. 12a + 43
#7. -7x + 5y + 28
#8. 3x + 3(not sure about the last exponent because It was really blury to see :/
Step-by-step explanation:
Sorry I cant do the last because I have to now :) I will try to answer it next time if It isn't already answered :)
Answer:
x = 7√2/3
decimal = 3.299831
Step-by-step explanation:
Subtract 1 from both sides
3√2x+1-1=15-1
Simplify
3√2x=14
Divide both sides by 3√2
3√2x/3√2 = 14/3√2
Simplify
x= 7√2/3
The answer should be 1/9y^4
From the graph,
f(0) = 1
Notice that when x = 0, y = 1.
If we plot the point (0,1) It's the same point. So f(0) = 1 is basically substituting x = 0 and get y = 1
Answer:
This does represent an exponential function , because his savings increase by a constant rate
Step-by-step explanation:
Let
x -----> the number of weeks
y ----> the amount saved
In this problem we have a exponential function of the form
where
a is the initial value
b is the base
r is the rate of change
where
---- because he doubles the amount each week
----> 
substitute
therefore
This does represent an exponential function , because his savings increase by a constant rate
