Use an element argument to prove the statement. (Assume that all sets are subsets of a universal set U.)
Statement: For all sets A, B, and C, (A − B) ∩ (C − B) = (A ∩ C) − B.
Answer and Step-by-step explanation:
Solution:
Given:
A, B and C are sets.
We have to prove that:
(A − B) ∩ (C − B) = (A ∩ C) − B.
Use an element x,
Let x Є (A – B), by the definition of difference:
X Є A and x ∉ B.
And
X Є A ∩ C and x ∉ B
X Є (A ∩ C) – B
Now let x Є C – B
By the definition of difference:
X Є C and x ∉ B
By definition of intersection: x Є C and x Є( A ∩ C)
By definition of difference, using that x Є(A ∩ C) And x ∉ B:
X Є ( A ∩ C) – B
We know that: x Є (A – B) ∩ ( C – B)
Is equivalent to x Є A – B and x Є C – B
So, ( x Є A and x ∉ B)
And (x Є C and x ∉ B)
From this we know that x Є (A ∩ C) – B.

0.3d-1/3 1/3=.84:7/15
Answer:
[tex]d=\frac{147}{6.3}[/tex]
Step-by-step explanation:
The right side is a ratio [tex]0.84:\frac{7}{15}[/tex] a ratio can be written as a fraction [tex]\frac{0.84}{\frac{7}{15} }[/tex] this means [tex]0.84[/tex] divide by [tex]\frac{7}{15}[/tex] which is the same as [tex]0.84*\frac{15}{7}=\frac{12.6}{7}[/tex] On the left, change the mixed fraction [tex]3\frac{1}{3}[/tex] to the improper fraction [tex]\frac{10}{3}[/tex] Then divide [tex]0.3d-1[/tex] by [tex]\frac{10}{3}[/tex] which is same as [tex](0.3d-1)*\frac{3}{10} =\frac{3(0.3d-1)}{10}[/tex] So the equation is now [tex]\frac{3(0.3d-1)}{10}=\frac{12.6}{7}[/tex] Now multiply both sides by 10 and 7:[tex](10)*(7)*\frac{3(0.3d-1)}{10}=\frac{12.6}{7}*(7)*(10)\\7*3(0.3d-1)=12.6*(10)\\21*(0.3d-1)=126\\6.3d-21=126\\6.3d-21+(21)=126+(21)\\6.3d=147\\d=\frac{147}{6.3}[/tex]Answer:
d=147/6.3
Step-by-step explanation:
d = 147 / 6.3

what is the value of x in 9/5 x = 2/3
Answer:
x = 10/27
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
9/5x = 2/3
Step 2: Solve for x
Divide both sides by 9/5: x = 10/27Step 3: Check
Plug in x to verify it's a solution.
Substitute: 9/5(10/27) = 2/3Multiply: 90/135 = 2/3Simplify: 2/3 = 2/3And we have our final answer!
Answer:
x = 10/27
Step-by-step explanation:
2/3 ÷ 9/5
2/3 x 5/9 = 10/27

Write the cubic polynomial function f(x)in expanded form with zeros −6, −4,and −1,given that f(−2)=−32.
Answer:
[tex]f(x)=4x^3+44x^2+136x+96[/tex]
Step-by-step explanation:
Polynomials
It's possible to build a polynomial function by knowing its zeros and leading coefficient.
Given the zeros of a third-degree polynomial: x=x1, x=x2, and x=x3, the function is:
[tex]f(x)=a(x-x_1)(x-x_2)(x-x_3)[/tex]
Where a is the leading coefficient.
We are given the zeros -6, -4, and -1, thus:
[tex]f(x)=a(x+6)(x+4)(x+1)[/tex]
The value of a can be calculated by substituting the point (-2,-32):
[tex]a(-2+6)(-2+4)(-2+1)=-32[/tex]
Calculating:
[tex]a(4)(2)(-1)=-32[/tex]
[tex]-8a=-32[/tex]
Dividing by -8:
[tex]a = -32/(-8) =4[/tex]
a = 4.
The polynomial is now complete:
[tex]f(x)=4(x+6)(x+4)(x+1)[/tex]
Operating:
[tex]f(x)=4(x^2+10x+24)(x+1)[/tex]
[tex]f(x)=4(x^3+11x^2+34x+24)[/tex]
[tex]\mathbf{f(x)=4x^3+44x^2+136x+96}[/tex]

Step-by-step explanation:
Cross multiply. 0.3x=0.35x-3.5. Subtract 0.35x to get -0.05x=-3.5. Multiply by -1 to get 0.05x=3.5. And (5/100)x=7/2. Divide by 5/100 to get 700/10=70.
