Since 3 poles is $120 and 4 poles is $160
you can find the difference between the two to find the price of one pole

160-140 = 20

each pole is $20

you can then do the equation

$120 = 20(3)+ y

3 being the amount of poles and y being the fee added to it.

120 = 60 + y

y = 60

so the final answer would be c = 20n + 60

Answer:

  • 1/3

Step-by-step explanation:

Total outcomes

  • 1, 2, 3, 4, 5, 6 - six

Favorable outcomes

  • 1, 2 - two

Probability

  • P( < 3) = favorable outcomes / total outcomes = 2/6 = 1/3

Determine which equation is written in function form:
Mila [183]

<em>Greetings from Brasil... </em>

A 1st degree function can be written in two ways:

F(X) = AX + B

or

Y = AX + B

note that F(X) = Y

So, looking at the alternatives in the question, only Y = 7X/3 - 8 is equivalent to Y = AX + B, where:

A = 7/3

B = - 8

then

\large{\boldsymbol{\mathbf{Y = \frac{7X}{3}-8\Leftrightarrow Y=AX+B}}}   <em>a function of the 1st degree</em>

answer:

<h2>Y = (7/3)X - 8</h2>

Use algebraic methods to prove that the given function has an x-intercept that is equal to its y-intercept. In your final answer
Llana [10]

Given the function, y = x/( x^2 – 1)

Add x and subtract x from (x^2 – 1) to make it a complete square

y = x/(x^2 + x – x – 1)

 y = x/[x(x + 1) – 1(x + 1)]

y = x/[(x – 1)(x + 1)]

 

 

In order to find the y -intercept, we set x = 0

When x = 0

y = 0/[(0 – 1)(0 + 1)]

y = 0.

Therefore, the y-intercept is zero.

 

In order to find the x -intercept, we set y = 0

When y = 0

0 = x/[(x – 1)(x + 1)]

The only way the product of a division will be zero is if the numerator is zero

So, if x/[(x – 1)(x + 1)] = 0

x = 0

Therefore, the x-intercept is also zero.

 

Since both x- intercept and y- intercept equal zero,

Then, the given function has an x-intercept that is equal to its y-intercept
