Answer:
x= 112
Step-by-step explanation:
Answer:
R 42.26
Step-by-step explanation:
To calculate the bill correctly we must add the orders separately and in the sweet cost when adding, we should write it as 0.59 not 59.
my order my friend's order
20.50 10.29
+ 10.29 + 0.59
<u> </u> 0.59
R 30.79 <u> </u>
R 11.47
<em>R 30.79 + R 11.47 = </em><em>R 42.26</em>
Below are suppose the be the questions:
a. factor the equation
<span>b. graph the parabola </span>
<span>c. identify the vertex minimum or maximum of the parabola </span>
<span>d. solve the equation using the quadratic formula
</span>
below are the answers:
Vertex form is most helpful for all of these tasks.
<span>Let </span>
<span>.. f(x) = a(x -h) +k ... the function written in vertex form. </span>
<span>a) Factor: </span>
<span>.. (x -h +√(-k/a)) * (x -h -√(-k/a)) </span>
<span>b) Graph: </span>
<span>.. It is a graph of y=x^2 with the vertex translated to (h, k) and vertically stretched by a factor of "a". </span>
<span>c) Vertex and Extreme: </span>
<span>.. The vertex is (h, k). It is a maximum if "a" is negative; a minimum otherwise. </span>
<span>d) Solutions: </span>
<span>.. The quadratic formula is based on the notion of completing the square. In vertex form, the square is already completed, so the roots are </span>
<span>.. x = h ± √(-k/a)</span>
