The function that is a reflection of f(x) over the y-axis is h(x) = 2(0.35)^(-x)
<h3>How to determine the reflection?</h3>
The equation is given as:
f(x) = 2(0.35)^x
The reflection of a function over the y-axis is :
f'(x) = f(-x)
So, we have:
f(-x) = 2(0.35)^(-x)
From the list of options, we have
h(x) = 2(0.35)^(-x)
Hence, the function that is a reflection of f(x) over the y-axis is h(x) = 2(0.35)^(-x)

Answer:
X = 56/14 = 4
Step-by-step explanation:
Answer:
option B
Step-by-step explanation:
First Quartile = 14
Common difference is -2-5 = -7
first term is 5
a_50 = 5 -7(50-1) = -338
2) d = 3 - (-7) = 10
a = -7
a_110 = -7 + 10(110 - 1) = 1083
d = -27 - (-22) = -5
second -7 - 5= -12
third = -12 - 5 = -17
So, we know this:
<span> 5x+10y = 800
and we also know that the number of larger vehicles was 50.
So we can substitute:
</span>
<span>5x+10y = 800
</span>
<span>5x+10*50 = 800
and calculate:
</span><span>5x+500 = 800
and now subtract 500 from both sides:
5x=300
and divide by 5:
x=60.
and this is our answer: there were 60 smaller vehicles washed!
