X: y = 1:5 Which is the correct equation? A y = 5x By= C y=x-4 D y=x+4

Ymorist [56]

The answer should be A. For example, if x = 1, and the ratio between x and y is y is 5 times greater than x, then y would equal 5, which is only true in A.

Or, use the number 5 as an example. If x = 5, and the ratio between x and y is y is 5 times greater than x, then y is 5.

And if you put that into A, y = 5x, it becomes 25 = 5(5)
Then 25 = 25, which is true!

Math help please! Simplify: <br> √(4 + 16 + 16√3 + 12) = 4√(2 + √3)

lozanna [386]

Both sides equal each other. Do you want to know how?

√(4 + 16 + 16√3 + 12) = 4√(2 + √3)

Surd Rule: Numbers with the same surd can be added together. Therefore, all whole integers can be added together.

√(4 + 16 + 16√3 + 12)

√((4 + 16 + 12 )+ 16√3 ) =

√(32 + 16√3)

Simplify by Factorising the common factor - 16

√(32 + 16√3) ÷ 16

√(16 (2 + √3))

Square root 16. This is because it is a not a surd because it is not in it's simplest form.

√16 = 4

√4 (2 + √3)

The local ice cream shop surveyed their costumers to see wich flavor of ice cream is most popular.125 people chose chocolate as

svlad2 [7]

Answer: The total costumers were surveyed = 500

Step-by-step explanation:

Let x = total costumers were surveyed.

Given : 125 people chose chocolate as their favorite flavor, which represents 25% of the costumers surveyed.

25% of x = 125

$\Rightarrow\ \dfrac{25}{100}\times x = 125\\\\\Rightarrow\ \dfrac{1}{4}x=125\\\\\Rightarrow\ x=125\times4\\\\\Rightarrow\ x= 500$

Hence, the total costumers were surveyed = 500

Determine whether the degree of the function is even or odd and whether the function itself is even or odd.

Fynjy0 [20]

Answer:

There are Even, Odd and None of them and this does not depend on the degree but on the relation. An Even function: $f(-x)=f(x)$ And Odd one: $-f(x)=f(-x)$

Step-by-step explanation:

1) Firstly let's remember the definition of Even and Odd function.

An Even function satisfies this relation:

$f(-x)=f(x)$

An Odd function satisfies that:

$-f(x)=f(-x)$

2) <u>Since no function has been given</u>. let's choose some nonlinear functions and test with respect to their degree:

$f(x)=x^{2}-4, g(x)= x^{5}+x^{3}$

$f(x)=x^2 -4\Rightarrow f(-x)=(-x)^{2}-4\Rightarrow f(-x)=x^{2}-4\therefore f(x)=f(-x)$

$g(-x)=-(x^{5}+x^{3})\Rightarrow g(-x)=-x^{5}-x^{3}\Rightarrow g(-x)=-g(x)$

3) Then these functions are respectively even and odd, because they passed on the test for even and odd functions namely, $f(-x)=f(x)$ and $-f(x)=f(x)$ for odd functions.

Since we need to have symmetry to y axis to Even functions, and Symmetry to Odd functions, and moreover, there are cases of not even or odd functions we must test each one case by case.
