Step-by-step explanation:
hope this helps i took the test
Answer:
Part A)
1) 
2) 
Part B)
1) 
2) 
Step-by-step explanation:
Part 1) x and y vary inversely and x=50 when y=5 find y when x=10 what is k?
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form 
or 
step 1
<u>Find the value of k</u>
x=50 when y=5
substitute the values
------> 
----->
The equation is equal to
or 
step 2
<u>Find y when x=10</u>
substitute the value of x in the equation and solve for y
Part B) x and y vary directly and x=6 when y=42 find k what is y when x=12
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form 
or 
step 1
<u>Find the value of k</u>
x=6 when y=42
substitute the values
------> 
----->
The equation is equal to
or 
step 2
<u>Find y when x=12</u>
substitute the value of x in the equation and solve for y
Answer:
Below
Step-by-step explanation:
Substituting the given values:
f(6) = 6(2/3) - 2 = cube root of 6^2 - 2 = cube root 36 - 2
f(-6)= (-6)(2/3) - 2 = cube root of(-6)^2 - 2 = cube root 36 - 2
So This is true,
f(6) = cube root of 6^2 - 2 = cube root 36 - 2 = 1.3019
2 * f(3) = 2 * (cube root of 3^2 - 2 ) = 2 * (cube root of 9 - 2) = 0.1602
So False,
The answer is B: a^3b^4<span>
Proof:
Simplify the following:
(a^7 b^8)/(a^4 b^4)
Combine powers. (a^7 b^8)/(a^4 b^4) = a^(7 - 4) b^(8 - 4):
a^(7 - 4) b^(8 - 4)
7 - 4 = 3:
a^3 b^(8 - 4)
8 - 4 = 4:
Answer: a^3 b^4
PS: I just wish that you put the equation down as it's intended i.e.
a^7b^8/a^4b^4 is not the same as (<span>a^7b^8)/(a^4b^4)</span>

Answer:
A. An irrational number
D. A fraction
Step-by-step explanation:
Nonrepeating numbers are number/decimal that continues endlessly with no set of numbers alike or repeating theirself
while nonterminating numbers are numbers that do not have an end
examples can be a fraction, irrational numbers
