Define a quadratic function y=f(x) that satisfies the given conditions,

vertex (5, -1) and passes through (0, -76).

f(x)=

The quadratic function f(x)=15x-76

Solution:

As given in the problem, the two points are and

We know the slope

Now substituting the value of points we get,

We know the equation of a line at a given point is

Let us take the point (5,-1) for the equation, then we get

Multiplying the signs,

Hence, the function f(x) is

a

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
