Simplify: 5x - 6y + 4x
A) 9 x - 6 y
B) 3 xy
C) x - 6 y

Answer:

a = cd + b / b

Explanation:

ba − cd = b

[ Step 1: Add cd to both sides ]

ab − cd + cd = b + cd

ab = cd + b

[ Step 2: Divide both sides by b ]

ab / b = cd + b / b

a = cd + b / b

Answer: A

Step-by-step explanation:

If you look at the line segment, it states that EG is 12. Now, we add EF and FG to get the value of x.

6x-8+2(x+2)=12          [distribute]

6x-8+2x+4=12            [combine like terms]

8x-4=12                       [add both sides by 4]

8x=16                          [divide both sides by 8]

x=2

Now, we know that A is the correct answer.

Answer:

9

Step-by-step explanation:

Let the two perfect cubes be x and y where x > y.

According to the given conditions:

[tex] {x}^{3} - {y}^{3} = 386...(1) \\ y = 7...(2) \\ plug \: y = 7 \: in \: equation \: (1) \\ {x}^{3} - {7}^{3} = 386 \\ {x}^{3} - 343 = 386 \\ {x}^{3} = 343 + 386 \\ {x}^{3} = 343 + 386 \\ {x}^{3} = 729 \\ x = \sqrt[3]{729} \\ x = 9[/tex]

Thus the cube root of the larger number is 9.

Building and solving an equation, it is found that the cube root of the larger number is 9.

-------------------------

[tex]x^3 - y^3 = 386[/tex]

[tex]x^3 - y^3 = 386[/tex]

[tex]x^3 - 7^3 = 386[/tex]

[tex]x^3 - 343 = 386[/tex]

[tex]x^3 = 386 + 343[/tex]

[tex]x^3 = 729[/tex]

[tex]x = \sqrt[3]{729}[/tex]

[tex]x = 9[/tex]

Thus, the cube root of the larger number is 9.

Answer:

See explanation

Step-by-step explanation:

It is impossible to take the square root of a negative number. Try any value, nothing works. [tex]2^2 = 4[/tex], and [tex]-2^2 = 4[/tex]. It just doesn't work. This is why there is no real number that satisfies [tex]\sqrt{-4}[/tex] (however it is represented as [tex]2i[/tex], i being "the imaginary number" that mathematicians made up to represent it).

When we are finding the cube root of a number, we are looking for a number that when multiplied by itself 3 times, will equal the number.

This is different than squared. Any number, positive or negative, squared will be positive. However, we can test out values and see we can end up with a negative when cubing.

For example: [tex]5^3 = 5\cdot 5\cdot 5 = 125[/tex]

HOWEVER:

[tex]-5^3 = -5 \cdot -5 \cdot -5 = -125[/tex]

We know that [tex]2^3 = 8[/tex], this means that [tex]-2^3 = -8[/tex] (as [tex]-2 \cdot -2 \cdot -2 = -8[/tex])

Answer:

Yes.

Step-by-step explanation:

Rational numbers can be represented as fractions with integers. The denominator must not equal 0.

[tex]\frac{7}{9}[/tex] is already in this form. This means that it's a rational number.

Hope this helps.

Yes, 7/9 is a rational number. A rational number is any number that can be expressed as a fraction of two integers, where the denominator is not zero.

In this case, 7/9 can be written as the fraction where the numerator (7) and denominator (9) are both integers. Since there is no division by zero, 7/9 qualifies as a rational number.

Rational numbers can be represented as terminating decimals or repeating decimals. When we divide 7 by 9, we get the decimal representation 0.777... where the digit 7 repeats infinitely. This is a repeating decimal, and it's still considered rational because it can be expressed as the fraction 7/9.

In conclusion, 7/9 is a rational number since it can be expressed as the fraction of two integers, and it can be represented as a repeating decimal.

It is NOT a function.

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function. X = y2 would be a sideways parabola and therefore not a function. Good test for function: Vertical Line test. If a vertical line passes through two points on the graph of a relation, it is not a function. A relation which is not a function. The x-intercept of a function is calculated by substituting the value of f(x) as zero. Similarly, the y-intercept of a function is calculated by substituting the value of x as zero. The slope of a linear function is calculated by rearranging the equation to its general form, f(x) = mx + c; where m is the slope.

A relation that is not a function

As we can see duplication in X-values with different y-values, then this relation is not a function.

A relation that is a function

As every value of X is different and is associated with only one value of y, this relation is a function.

[tex] QR = 2x - 1 [/tex]

[tex] PR = 21 [/tex]

Required:

Value of x

SOLUTION:

Point P, Q, and R are collinear, therefore:

[tex] PQ + QR = PR [/tex] (segment addition postulate)

[tex] (x - 5) + (2x - 1) = 21 [/tex] (substitution)

Solve for the value of x using the above equation.

[tex] x - 5 + 2x - 1 = 21 [/tex]

Combine like terms

[tex] x + 2x - 5 - 1 = 21 [/tex]

[tex] 3x - 6 = 21 [/tex]

Add 6 to each side of the equation

[tex] 3x - 6 + 6 = 21 + 6 [/tex]

[tex] 3x = 27 [/tex]
