The vertex form of all expressions is given below.
We have given that the expressions
We have to write the function in vertex form.
<h3>What is the vertex form of the equation?</h3>
The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.
Therefore the first equation

it can be written as

The second equation can be written as

vertex for is,

The third equation is,

Vertex form is,

Forth equation is,

Vertex form is,

Answer:
$568.75
Step-by-step explanation:
To find the markup, we multiply the original price by the percentage of markup
Markup = 175 * 225%
=175 * 2.25
=393.75
The new price is the markup plus the original price
New price = markup+ original price
=393.7+175
=568.75
Explanation:
The equation for this problem can be modeled in y = mx + b form.
m represents the rate of change and b represents the initial value or constant.
y = 10x + 20
x represents the number of hours he spent delivering newspapers
y is his total money after whatever number of hours he worked
The rate is 10, because it determines how much money he earns for each hour.
The y-intercept is 20, representing the starting amount of money in his bank account.
False. Both answers are 7. So they are equal
