Answer:

Step-by-step explanation:

We know that 7a+13<48. This inequality can be simplified by rearranging.

Subtracting 13 from both sides: 7a<48-13

Therefore this becomes: 7a<35

Dividing both sides by 7: a<5

Since the inequality simplifies to a<5, the answer is C

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
$y=a(x-h)^{2}+k$

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

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

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

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

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

If the cost is $138.25 and the desired markup is 12.5%, then what is the price after markup?

KIM [24]

First, you must turn the 12.5% into a decimal, which would then become .125. You then multiply that by the $138.25 and you would get 17.28. Then you just add the $138.25 to the $17.28 where you would then get $155.53 as your answer. Please let me know if I am wrong.
