So basically just add the equations to get rid of y. Then solve for x and plug into one of the equations for y. (1,4)

Is this correct help plzz
const2013 [10]
None of the offered choices is correct.

The radical cannot be simplified. If rewritten, it must be written as something like
x \sqrt[3]{ \frac{6}{x}}
or
\frac{6x}{ \sqrt[3]{36x}}

Stock worth $80 a share dropped in value by 15% on Tuesday, then increased by $7 the next Wednesday and, finally, increased by 1
Nutka1998 [239]
<h2>Steps</h2>

So here are a couple expressions when a value changes by percentage (p = percentage in decimal form and m = original value):

  • When <em>decrease</em>: (1 - p)m
  • When <em>increase</em>: (1 + p)m

So firstly, the $80 share dropped by 15%. Since this is a <em>decrease</em>, follow the appropriate expression:

15\%=0.15\\\\(1-0.15)*80\\0.85*80\\68

<em>On Tuesday, the share went from $80 to $68</em>

Next, on Wednesday the share increased by $7. With this, just add $68 and 7.

68+7=75

<em>On Wednesday, the share went from $68 to $75</em>

Lastly, on Thursday the share increased by 12%. Since this is an <em>increase</em>, follow the appropriate expression:

12\%=0.12\\\\(1+0.12)*75\\1.12*75\\84

<h2>Answer</h2>

<u>The final price of the share is $84.</u>

The equation of line p is y=ax+b. Which of these could be the equation of line q? A.y=−3a(x+6)+b
Ilia_Sergeevich [38]
The slope of line q is that of line p scaled by a factor of 3 (not -3). The y-intercept of line q is 6 less than the y-intercept of line p. The appropriate choice is
  D. y = 3ax +b -6
