For the fraction you start off by putting 80 over 100 and start simplifying which gives you 4/5 as for a mixed number or a whole number it isn't possible since it isn't a total whole. In order for you to have a mixed number you need something over a whole or something over a 100%

A percent can be viewed as a fraction over 100, so in this case, we form the fraction 80/100.

However, this is not in simplest form. The largest number that goes into both of these (greatest common factor) is 20, so we should divide the numerator and denominator by 20.

When we do this, we can see that the simplest fraction to represent 80% is 4/5.

Using the completing-the-square method, rewrite f(x) = x2 + 10x + 7 in vertex form
mr Goodwill [35]

Answer:

f(x) = (x - (-5))^2 + (-18)

Step-by-step explanation:

Given:

f(x) = x^2 + 10x + 7

Rewrite f(x) in vertex form

Solution:

f(x) = ax^2 + bx + c is a quadratic function.

The vertex form of f(x) is a(x - h)^2 + k, where (h, k) is the vertex.

=> f(x) = x^2 + 10x + 7

          = x^2 + 10x + 25 - 18

          = (x + 5)^ - 18

          = (x - (-5))^2 + (-18)

=> f(x) can be rewritten in form of a(x - h)^2 + k, where (h, k) is the vertex, with a = 1, h = -5, k = -18
