Joy is going to solve the equation below which of the following represents the equation after just distributing and combining like terms

Answers

The correct option is b. -30x + 32 = 182.

After combining the like terms, the equation that represents -8x + 23 - 22x + 9 = 182 is -30x + 32 = 182, where x = -5.

What is defined as equation?

In its most basic form, an equation is a statement that demonstrates that 2 mathematical expressions have been equal.

3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are 2 expressions separated by a 'equal' sign.An equation is a formula in mathematics that conveys the equality of two expressions by linking them with the equal sign =.

Now, as per the given question;

The stated equation in the question is is,

-8x + 23 – 22x + 9 = 182

Considering like terms together;

-8x – 22x + 23 + 9 = 182

Further simplifying;

– 30x + 32 = 182

Subtracting 32 from the both sides.

– 30x + 32 - 32 = 182 - 32

On solving;

– 30x = 150

⇒ x = -5

Therefore, the expression which defined the equation after taking alike terms is -30x + 32 = 182 for which the value of 'x' comes to be -5.

What is a simple definition for function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input

a constant function is a function whose (output) value is the same for every input value. For example, the function y(x) = 10 is a constant function because the value of y(x) is 10 regardless of the input value x

if we take f(x)= x+1

then put x=9 we get f(9)= 10

Convert the polar equation to rectangular form and identify the graph. Support your answer by sketching the graph. Show and explain your work.

Answers

The polar equation r = - 4 · cos θ is equivalent to the equation of the circle (x + 2)² + y² = 2², whose radius is 2 and center is (h, k) = (- 2, 0).

How to transform a polar expression into its rectangular form

Polar and rectangular forms are related by this relation: (x, y) → (r · cos θ, r · sin θ), where r is the radial distance with respect to the origin and θ is the angle in standard position. We can use this fact to change the given expression into its rectangular form:

r = - 4 · (x / r)

r² = - 4 · x

x² + y² = - 4 · x

y² = - (x² + 4 · x)

y² - 4 = - (x² + 4 · x + 4)

y² - 4 = - (x + 2)²

(x + 2)² + y² = 4

(x + 2)² + y² = 2²

In a nutshell, the polar equation r = - 4 · cos θ is equivalent to the equation of the circle (x + 2)² + y² = 2², whose radius is 2 and center is (h, k) = (- 2, 0).

Using the Factor Theorem, the non-real solutions are given as follows:

[tex]\frac{1 + \sqrt{5}i}{3}, \frac{1 - \sqrt{5}i}{3}[/tex]

What is the Factor Theorem?

The Factor Theorem states that a polynomial function with roots [tex]x_1, x_2, \codts, x_n[/tex] is given by:

[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]

In which a is the leading coefficient.

For this problem, the function is:

f(x) = 3x^5 + 25x^4 + 26x³ - 82x² + 76x - 48.

The function can be written as:

f(x) = g(x)h(x).

In which:

g(x) is the polynomial with the real solutions.h(x) is the polynomial with the non-real solutions.

Using a calculator, as the graph is not given, the real solutions are given as follows:

[tex]x_1 = -6, x_2 = -4, x_3 = 1[/tex]

Hence:

g(x) = (x + 6)(x + 4)(x - 1)

g(x) = (x² + 10x + 24)(x - 1)

g(x) = x³ + 9x² + 14x - 24.

f(x) is of degree 5, g(x) of degree 3, hence h(x) is of degree 2 and:

f(x) = g(x)h(x)

3x^5 + 25x^4 + 26x³ - 82x² + 76x - 48 = (x³ + 9x² + 14x - 24)(ax² + bx + c)

Hence:

ax^5 = 3^5 -> a = 3.-24c = -48 -> c = 2.

-24bx + 14cx = 76x

-24b + 28 = 76

-24b = 48

b = -2.

Then the equation with the non-real solutions is:

h(x) = 3x² - 2x + 2.

Which is a quadratic equation with coefficients a = 3, b = -2 and c = 2, thus:

[tex]\Delta = b^2 - 4ac = (-2)^2 - 4(3)(2) = -20[/tex][tex]x_1 = \frac{2 + \sqrt{-20}}{6} = \frac{2 + 2\sqrt{5}i}{6} = \frac{1 + \sqrt{5}i}{3}[/tex][tex]x_2 = \frac{2 - \sqrt{-20}}{6} = \frac{2 - 2\sqrt{5}i}{6} = \frac{1 - \sqrt{5}i}{3}[/tex]

Step-by-step explanation: First find the ratios. One juice is 70% and the other is 95%. Your goal is 85%. This is 15% from 70 and 10% from 95. This means you need (15)/(15+10) of 95, which is 3/5 of all the juice to be 95. This means you will need more of the 95% juice, which makes sense because 85 is closer to 95. So 3:5 and total 150=56.25 of 70% and 93.75pints of 90%

The function is represented as

A(t) = A * (1 + r)^t

So, we have

A(t) = 1 * (1+3)^t
