300%

Part 2: I'm not sure what the problem means, but if it means the original price, then it is c/3 or 1/3c. If it is referring to the resale price, then it is 300%c or 3c.

How do you complete the square to rewrite y= x^ -6x + 15 in vertex form

Vaselesa [24]

Vertex form of a quadratic equation is $y=a(x-h)^{2}+k$
where (h, k) is the vertex.

Our aim is to write the expression $y=x^{2} -6x+15$ in the form
$y=a(x-h)^{2}+k$

$y=x^{2} -6x+15$

$y=x^{2} -2*3*x+15$

$y=(x^{2} -2*3*x+ 3^{2})-3^{2}+ 15$

$y=(x-3)^{2}-9+15$

$y=(x-3)^{2}+6$

ankoles [38]

Answer:

t = 1.025c + 5.99

Step-by-step explanation:

Recall : general for of a linear equation is given by :

y = mx + c

Given the following :

Item cost = c

Shipping charge = $5.99

Tax on purchases = 2.5%

Total cost, t

t = c + tax + shipping cost

Tax on purchase : 2.5% * item cost ; 0.025c

Shipping = $5.99

Hence,

Total cost, t = c + 0.025c + 5.99

t = 1.025c + 5.99

Sam takes x minutes yo walk from home to library and 5 minutes more to walk from the library to school than fron home to the lib

LuckyWell [14K]

Answer:

$2x+5\ minutes$

Step-by-step explanation:

Given:

Sam takes x minutes yo walk from home to library.

And takes 5 minutes more to walk from the library to school than from home to the library.

Express the total time taken for Sam to walk from home to school via the library in terms of x.

<u>Solution:</u>

Time taken by Sam to walk from home to library = $x\ minutes$

Time taken by Sam to walk from library to school = $x+5\ minutes$

Total time taken by Sam to walk from home to school via the library = Time taken to walk from home to library + Time taken to walk from library to school

Total time taken = $x+x+5=2x+5$

Therefore, the total time taken for Sam to walk from home to school via the library is $2x+5\ minutes$
