We can also use a proportion.

5/8 = x/16

8x = 5 × 16

x = 5 × 2

x = 10

The term (- x² + 2x + 1 ) must be subtracted from (x² + 2x - 3) to get

(2x² - 4).

Here,

We have to find the number which must be subtracted from x² + 2x - 3 to get 2x² - 4.

What is Number system?

A system of writing to express the number is called number system.

Now,

Let 'a' must be subtracted from x² + 2x - 3 to get 2x² - 4.

It can be written as;

(x² + 2x - 3) - a = 2x² - 4

a = (x² + 2x - 3) - (2x² - 4)

a = x² + 2x - 3 - 2x² + 4

a = - x² + 2x + 1

Therefore, The term (- x² + 2x + 1 ) must be subtracted from x² + 2x - 3 to get 2x² - 4.

It is not a function because: C) the element 1 is in both the domain and the range.

A relation can be defined as a function if each of the domain values each has exactly one corresponding range value. This means that an element of the domain must not have two different elements from the range that it is related or corresponded to.

In the given function, 1 as an element of the domain is related to two different range elements, 10 and 7. This doesn't satisfy a function property.

The towns are 15600 miles apart.  

The term "map scale" refers to the proportion between a distance on a map and its corresponding distance on the ground. Lets see an example like, On a map with a scale of 1:100,000, one kilometer on the ground is equivalent to one centimeter. The scale of a map refers to the proportion between a distance on a map and its actual distance on the ground. This simple concept is complicated by the fact that scale must vary across a map due to the curvature of the Earth's surface. The concept of size is now important in two different ways as a result of this development.

The size of the producing globe is compared to the size of the Earth in the first technique. a theoretical globe known as the generating globe, upon which the map is projected and the Earth is compressed. The ratio of the size of the Earth to that of the generating globe is known as the nominal scale, also known as the major scale or representative fraction.

∵ 1 inch = 50 miles on the map

Answer:the iconic Indian building named Taj Mahal

Step-by-step explanation:

One way to solve is to follow these steps

2(3b - 2) = 2(2b + 12)

2*3b - 2*2 = 2*2b + 2*12

6b - 4 = 4b + 24

2b = 28

b = 28/2

b = 14

Answer:

y = 2x

Step-by-step explanation:

The slopes of two perpendicular lines are negative reciprocals of each other. So the slope is 2

m = 2, y = -4, x = -2

y = mx + b

-4 = 2(-2) + b

b = -4 + 4

b = 0

y = 2x

Answer: 56.25 of 70% and 93.75pints of 90%

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%

f(x)=x+1 is a formula for a function f(x) that has f(9)=10

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

Hence , f(x)=x+1 is a formula for a function f(x) that has f(9)=10

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).

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).

THE THIRD GRAPH IS THE PARABOLA!

HOPE THIS HELPS!

Answer:

consider the two number as x and y

first  given condition

x-6 = 3y

i.e. x= 3y + 6  eqn 1

second given condition

x+ y = 38

i.e. x= 38-y  eqn 2

solving eqn 1 and 2

3y + 6 = 38-y

3y + y = 38-6

4y = 32

y = 8

substituting the value of y in eqn 2

x = 38 - y

x= 38-8

x= 30

hence the required numbers are 8 and 30

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]

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:

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:

-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:

Hence the non-real solutions are:

Answer: x=21, y=8
