Answer:

x  = -5 \pm  \sqrt{26}

Step-by-step explanation:

x^2+10x-1=0\\\\\implies x^2+2\cdot 5 x +5^2-5^2-1=0\\\\\implies (x+5)^2-25-1=0\\\\\implies (x+5)^2 -26=0\\\\\implies (x+5)^2 = 26\\\\\implies x +5 = \pm\sqrt{26}\\\\\implies x  = -5 \pm  \sqrt{26}

The following trapezoid JKLM is translated by the rule (x - 2, y + 8). What are the coordinates for J'K'L'M'?
Andrew [12]

The coordinates of trapezoid vertices are:

  • J(-7,-2);
  • K(-4,-2);
  • L(-2,-5);
  • M(-9,-5).

The translation rule is

(x,y)→(x-2,y+8).

Then the image trapezoid vertices are:

  • J'(-7-2,-2+8) that is J'(-9,6);
  • K'(-4-2,-2+8) that is K'(-6,6);
  • L'(-2-2,-5+8) that is L'(-4,3);
  • M'(-9-2,-5+8) that is M'(-11,3)

Butoxors [25]
She can buy 2 bags of fruit (adds up to 9.50) and of course the box of crackers that is 3.5, in total it adds to $13. So the answer is she can buy 2 bags of fruit.
