Which of the following is equivalent to the image below
A: 6
B: 8
C: 12
D: 64
Answer: The answer is 8
Step-by-step explanation: first you solve 16 to the 1.5 power (3/2=1.5) and that gives you 64. Then 64 to the .5 power (1/2=.5) and that gives you 8.

solving systems of linear inequalities
Answer:
YES. (2, 7) is a solution of the system.
Step-by-step explanation:
System of linear inequalities has been given as,
y ≥ -x + 1 --------(1)
y < 4x + 2 ------(2)
If (2, 7) is a solution of the given system of inequalities, it will satisfy both the inequalities.
By substituting the coordinates of point (2, 7) in inequality (1),
7 ≥ -2 + 1
7 ≥ -1
True.
By substituting the coordinates of point (2, 7) in inequality (2),
7 < 4(2) + 1
7 < 9
True.
Therefore, point (2, 7) lie in the solution area of system of inequalities.
YES. (2, 7) is a solution of the system.

Step-by-step explanation
A
2^2 = 4
4^2 = 16
D
2^2=4
2^4 = 16
Answer:
A and D
Step-by-step explanation:
A.) plug in 2 first then 4
2^2= 4 and 4^2= 16 so it applies
B.) does NOT apply bc 2+6=8 and not f(2)=4 and also does not equal to 16
4+6=10
C.) does NOT apply bc 4(2)+2=10 and not to 4 and also does not equal to 16; 4(4)+2=18
D.) does apply 2^2=4 and 2^4=16

A stuffy normally costs $12, but this week it is on sale for $9. What is the Percent of Change on the stuffy?
Answer: 25%
Step-by-step explanation:
From the question, we are told that a stuffy normally costs $12, but that this week it is on sale for $9.
The Percent of Change on the stuffy will be calculated as:
= Change / Normal cost × 100
= (12 -9) / 12 × 100
= 3/12 × 100
= 1/4 × 100
= 25%
Element X is a radioactive isotope such that every 51 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 7500 grams, how long would it be until the mass of the sample reached 6900 grams, to the nearest tenth of a year?
Answer: It will take 6 years for 7500 grams of X to reach 6900 grams.
Step-by-step explanation:
Expression for rate law for first order kinetics is given by:
[tex]t=\frac{2.303}{k}\log\frac{a}{a-x}[/tex]
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
[tex]51=\frac{0.69}{k}[/tex]
[tex]k=\frac{0.69}{51}=0.0135years^{-1}[/tex]
b) for 7500 g to reach to 6900 g
[tex]t=\frac{2.303}{0.0135}\log\frac{7500}{6900}[/tex]
[tex]t=6years[/tex]
It will take 6 years for 7500 grams of X to reach 6900 grams.

I hope this helps!
Answer: x = 3
Step-by-step explanation:
we subtract 2 from both sides, in order to get the variable by itself.
x + 2 (- 2) = 5 (- 2)
x = 3

Barbie has a favorite number. The
quotient of her number and -4 is -90.
What is Barbie's favorite number?
Answer:
Is -4444444444
Step-by-step explanation:
Answer:
360
Step-by-step explanation:
A quotient is the result of a division problem.
We must multiply -4 and -90.
-4 • -90 = 360
(There is no - because a negative multiplied by a negative equals a positive.)
Which of the following best describes the graph below?
Answer:
The correct option is;
A. It is a one-to-one function
Step-by-step explanation:
A function f(x), is a one to one function when each value in the range is given by each unique value in the domain such that each "x" value produces a unique "y" value.
The given graph has a domain of -2 ≤ x < ∞
Within the domain plotted in the graph, all lines with equation "x" = -2, -1, 0..., 4, 5 crosses the graph only once, therefore, for each value of "x", there is only one value of "y", which gives the relationship between the "x" and "y" values as one to one function
Kim's hair grows at the rate of 1 2 inch per month. How many months will it take for her hair to grow 12 inches?
Answer:
24 months
Step-by-step explanation:
The computation of the number of months taken to grow 12 inches is as followS:
Given that
It takes half inches per month
i.e.
0.5 inches ........... 1 month
12 inches .......... ?
So for 12 inches it would take
= 12 inches ÷ 0.5 inches × 1 month
= 24 months

Answer:
70x
Step-by-step explanation:
8x8 = 64x then +6x = 70x
Answer:
[tex]2x(4x+3)[/tex]
Step-by-step explanation:
The first thing to factorising this expression is to find the greatest common factor (GCF). For 8x² and 6x the gcf is 2x. So now we divide the 8x² and 6x by the 2x. Which comes out to 4x and 3, these will be inside the parentheses.
So it'll factorise to [tex]2x(4x+3)[/tex] and remember when we are dividing with exponents we subtract the exponents. So [tex]\frac{8x^2}{2x}[/tex] we will divide the coefficients together that'll be 4 and now for the exponents the 2 on the x² minus the 1 on the x will equal 1 so it'll be just x we don't place a one or anything.

if 72 is 40% what is 100%?
Answer:
180
Step-by-step explanation:
If 40% = 72, 100% can be found like so:
40% = 72
100% = [tex]\frac{100}{1}[/tex] * [tex]\frac{72}{40}[/tex]
You can reduce 40 and 100 by 20 (or probably more, but I'll use 20)
So now we have:
[tex]\frac{50}{1}[/tex] * [tex]\frac{72}{20}[/tex] = [tex]\frac{3600}{20}[/tex]Divide, and you get 180.
To check, we can find 40% of 180.

Esma and Hunter were trying to solve the equation:
? + 8x = 22 - 8
They both agreed they should first subtract 2x and add 8 to both sides and rewrite the equation as
2? + 6x + 8 = 0.
Then Esma said, "I can complete the square. I can add 1 to both sides to rewrite this equation as
32 +63 +9 = 1, factor, and solve using square roots."
Hunter said, "I'll factor the left-hand side of the equation as (+ + 2)(x + 4) and solve using the zero
product property."
Whose solution strategy would work?
Choose 1 answer.
A. Only Esma's
B. Only Hunter's
