A first number is nine less than a second. The sum of the numbers is 45. Find the numbers.
oee [108]

Answer:

The first number is <u>18</u> and the second number is <u>27</u>.

Step-by-step explanation:

Given:

A first number is nine less than a second.

The sum of the numbers is 45.

Now, to find the numbers.

Let the second number be x.

And the first number be x-9.

The sum of the both numbers is 45.

According to question:

(x-9)+x=45.

⇒ x-9+x=45.

⇒ 2x-9=45.

<em>Adding both sides by 9 we get:</em>

⇒ 2x=54.

<em>Dividing both sides by 2 we get:</em>

⇒ x=27.

<u><em>The second number = 27</em></u>.

Now, to get the first number we put the value of x:

x-9

=27-9

=18.

Therefore, the first number is 18 and the second number is 27.

Answer:

  a) x = -1, x = 4

  b) y = x^2 -3x -4

Step-by-step explanation:

a) We observe the x-intercepts are x = -1 and x = 4. These are the solutions to y = 0, which is usually what we want in cases like this.

The solutions are x=-1 and x=4.

__

b) We know two of the factors are (x +1) and (x -4). There may be an additional constant factor for vertical scaling. One point we can check is the y-intercept.

  y = a(x +1)(x -4)

For x=0, this is ...

  y = a(1)(-4) = -4a

The y-intercept is y = -4, so we have a=1.

The factored equation is ...

  y = (x +1)(x -4)

Multiplying this out gives the equation in standard form:

  y = x^2 -3x -4

__

<em>Additional comment</em>

Your teacher may want the standard form equation to be ...

  x^2 -3x -4 = 0

This is the equation of two specific points: x=-1 and x=4. It is not the equation of the graph.
