Answer:
D.
Step-by-step explanation:
2^a*2^5/2^b = 2^(a+5)/2^b. using power of a product property.
then
2^(a+5)/2^b= 2^(a+5)*2^-b. Using Negative Exponent property.
Again we can use power of a product property and we get 2^(a+5)*2^-b=2^(a-b+5)
1. y=f(x)=170x-4 is a function with variable x representing a year.
2. Let's consider the difference between 2 consecutive years, say year 3 and year 4
f(3)=170*3-4
f(4)=170*4-4
we expect f(3)-f(4) to be 4 since after 4 years, the water will be 4 feet less than after 3 years.
check: f(3)-f(4)=(170*3-4)-(170*4-4)=170*3-4-170*4+4=170*3-170*4=170*(3-4)=170*(-1)=-170
Answer:
Step-by-step explanation:
x: adult ticket
y: child ticket
x + y = 52
3x + 2y = 136
-3x - 3y = -156
3x + 2y = 136
-y = -20
y = 20 child tickets
x + 20 = 52
x = 32 adult tickets

Answer:
D. 12
Step-by-step explanation:
D is the closest answer. -2 multiplied by a -1.8 is a +3.6. Then, you add 8 to 3.6 and you will get 11.6. Therefore, the answer you will put is D or 12
