Answer:
x = -121
Step-by-step explanation:
(7/2)*x+(1/2)*x = (9/2)*x+121/2 // - (9/2)*x+121/2
(7/2)*x+(1/2)*x-((9/2)*x)-(121/2) = 0
(7/2)*x+(1/2)*x+(-9/2)*x-121/2 = 0
-1/2*x-121/2 = 0 // + 121/2
-1/2*x = 121/2 // : -1/2
x = 121/2/(-1/2)
x = -121

A car is moving at a steady rate. The distance it travels is proportional to the amount of time, in hours, it has been driving. It has traveled a total of 168 miles in 3 hours. (a) What is the ratio of the distance to the number of hours? Express as a fraction and as a unit rate with appropriate units.
Step-by-step explanation:
let distance travelled be d miles and time be t hours.
d = kt where k is a constant, k ≠ 0
168 = 3k
k = 56
d/t = k
hence it's ratio is 56 : 1 and fraction is 168/3 = 56/1 and fraction with unit is 56miles/hour.

A Caterer Charges $275 for a 3 hour event
and $425 for a 5 hour event. What is the rate of change for this situation?
Given :
A Caterer Charges $275 for a 3 hour event and $425 for a 5 hour event.
To Find :
The rate of change for this situation.
Solution :
Price per hour ratio for 3 hour event :
[tex]R_1= \dfrac{275}{3}[/tex]
Price per hour ratio for 5 hour event :
[tex]R_2= \dfrac{425}{5}[/tex]
Now, change in ratio :
[tex]R = R_1-R_2\\\\R = \dfrac{275}{3}-\dfrac{425}{5}\\\\R = \dfrac{100}{15}\\\\R = \dfrac{20}{3}[/tex]
Therefore, rate of change for this situation is [tex]\dfrac{20}{3}[/tex] .
Hence, this is the required solution.

Find a polynomial function with leading coefficient 1 that has the given zeros, multiplicities, and degree. Zero: 2, multiplicity: 3 Zero: 0, multiplicity: 2 Degree: 5
Given:
Zero: 2, multiplicity: 3
Zero: 0, multiplicity: 2
Degree: 5
Leading coefficient = 1
To find:
The polynomial function.
Solution:
The general form of a polynomial is
[tex]P(x)=a(x-c_1)^{m_1}(x-c_2)^{m_2}...(x-c_n)^{m_n}[/tex]
where, a is a constant, [tex]c_1,c_2,...,c_n[/tex] are zeroes with multiplicity [tex]m_1,m_2,...,m_n[/tex].
Using the given information and the general form of a polynomial, we get
[tex]P(x)=a(x-2)^{3}(x-0)^{2}[/tex]
[tex]P(x)=ax^2(x^3-6x^2+12x-8)[/tex]
[tex]P(x)=a(x^5-6x^4+12x^3-8x^2)[/tex]
Leading coefficient is 1, so the value of a is also 1.
[tex]P(x)=1(x^5-6x^4+12x^3-8x^2)[/tex]
[tex]P(x)=x^5-6x^4+12x^3-8x^2[/tex]
Therefore, the required polynomial is [tex]P(x)=x^5-6x^4+12x^3-8x^2[/tex].
The polynomial for the conditions with leading coefficient 1 that has the given zeros, multiplicities, and degree. Zero: 2, multiplicity: 3 Zero: 0, multiplicity: 2 Degree: 5 is given as
[tex]\rm\bold{ y(x) = 1\times (x-2)^3(x-0)^2 }[/tex]
According to the given condition
The given conditions to write the polynomial equations are as follows
Zero 2 and Multiplicity 3
Zero 0 and Multiplicity 2
Degree of polynomial expression = 5
Leading coefficient of polynomial expression = 1
Let us consider the polynomial equation has only one variable and hence in general form we can write the equation of polynomial as follows
[tex]\rm y (x) = a(x-\alpha)^m (x-\beta)^n........(1)\\Where \\a = Leading \; coefficient\; of\; polynomial\; expression \\\alpha ,\beta = Roots \; of \; the\; polynomial\; expression\\m\; and \; n \; are \; multiplicities \; of \; the \; roots \; \alpha,\beta \; respectively\\Degree = m+n[/tex]
From the general form of polynomial expression as shown in equation (1) we can write
Polynomial expression for the given conditions is formulated in equation (2)
[tex]\rm y(x) = 1\times (x-2)^3(x-0)^2 .......(2)[/tex]
So the polynomial for the conditions given in question is expressed as
[tex]\rm\bold{ y(x) = 1\times (x-2)^3(x-0)^2 }[/tex]

A recipe for 4 cups of trail mix calls for 2··3cup of raisins. Aniyah has 1 1··2cups of raisins. Does Aniyah have enough raisins to make 14 cups of the trail mix? If not, how many more cups of raisins does Aniyah need?
Answer:
Aniyah does not have enough for 14 cups, and needs 1 1/6 more.
Using the required arithmetic concept, we can conclude that Aniya needs 7/6 more cups.
Representing the problem thus:
4 cups of trail = 2/3 cups of raisins
14 cups of trails = x
Cross multiply
4x = (2/3) × 14
4x = 28/3
x = (28/3) ÷ 4
x = (28/3) × (1/4)
x = 7/3
Cups of raisins Aniya has = 1 1/2 = 3/2
Extra cups needed = 7/3 - 3/2 = 7/6 cups
Therefore, Aniya does not have enough, she needs 7/6 more cups.
