Answer:
x = -55
Step-by-step explanation:
Subtract 7 on both sides first to get to this equation, x/5 = -11. Since there is a fraction on the left side, you have to multiply 5 on both sides to get your x-value which is -55.

Which of the following is equivalent to the image below
A: 6
B: 8
C: 12

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.

Factor the expression completely.
Answer:
Factoring the expression [tex]xy^4+x^4y^4[/tex] completely we get [tex]\mathbf{xy^4(x+1)(x^2-x+1)}[/tex]
Step-by-step explanation:
We need to factor the expression [tex]xy^4+x^4y^4[/tex] completely
We need to find common terms in the expression.
Looking at the expression, we get [tex]xy^4[/tex] is common in both terms, so we can write:
[tex]xy^4+x^4y^4\\=xy^4(1+x^3)[/tex]
So, taking out the common expression we get: [tex]xy^4(1+x^3)[/tex]
Now, we can factor the term (1+x^3) or we can write (x^3+1) by using formula:
[tex]a^3+b^3=(a+b)(a^2-ab+b^2)[/tex]
So, we get:
[tex]xy^4(1+x^3)\\=xy^4(x^3+1)\\Applying\:the\:formula\;of\:a^3+b^3\\=xy^4(x+1)(x^2-x+1)[/tex]
Therefor factoring the expression [tex]xy^4+x^4y^4[/tex] completely we get [tex]\mathbf{xy^4(x+1)(x^2-x+1)}[/tex]
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.

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%

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?

A. Only Esma's
B. Only Hunter's

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
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

When you load 8 identical chairs into a crate, the total weight is 66 lbs. When you load 11 of those same chairs into the same crate, the total weight is 84 lbs.
How many lbs does the crate weigh?
How much does each chair weigh?
Answer:
each chair weighs 6 lbs and the crate weighs 18 lbs.
Step-by-step explanation:
The solution is: 6 lbs does the crate weigh and, 18 lbs does each chair weigh.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
given that,
When you load 8 identical chairs into a crate, the total weight is 66 lbs. When you load 11 of those same chairs into the same crate, the total weight is 84 lbs.
let, each chair weigh = x
and, the crate weigh = y
so, we get,
the equations as:
8x + y = 66 ....(1)
11x + y = 84 ....(2)
now, solving this two equations,
we get,
subtracting (2) - (1),
3x = 18
or, x = 6
so, we have,
y = 18
Hence, The solution is: 6 lbs does the crate weigh and, 18 lbs does each chair weigh.
