The question asks that y is equal to 0. So the equation should be 0 = x² - 64. Now you can use the addition property of equality by adding 64 to both sides. This gives you x² = 64. Now, to find x, you need to find the root of 64, which is √64. However this can be simplified to a whole number 8. However, this isn't it. The answer actually can be 8 or -8, because -8² = 64 as well, because a negative multiplied by a negative is a positive. So your answer would be B. 8 or -8. Hope this helps. Feel free to ask questions about my explanation or any other questions you have.

Y = x^2 - 64
x^2 - 64 = 0
x^2 = 64
x^2 = 8^2
x = 8 and x = -8
answer is B. x = 8 and x = -8

BlackZzzverrR [31]

Answer:

x° =125° y°= 125°

Step-by-step explanation:

55° + x° = 180° because they are complementry angles

solve for x by subtracting 55° from both sides

x° = 125°

x° and y° is equal because they are vertical angles

Applying the Third Corollary to the Inscribed Angles Theorem A circle is shown. Points A, B, C, and D are on the circle. Lines c
Marat540 [252]

Answer:

  • ∠B = 110°
  • ∠D = 70°

Step-by-step explanation:

Opposite angles in an inscribed quadrilateral are supplementary, so ...

  ∠B +∠D = 180°

  (3x -4) +(2x -6) = 180

  5x = 190 . . . . . . . . . . . add 10, collect terms

  x = 38 . . . . . . . . . . . . . divide by 5

  ∠D = 2(38) -6 = 70

  ∠B = 180 -70 = 110

The measures of angles B and D are 110° and 70°, respectively.

shopkeeper purchased a bicycle for rupees 5000 and marked its price a certain percent above the cost price then he sold it at 10
Gennadij [26K]

Lets say the final price of the bike is SP plus 13% VAT. So:

1.13 * SP = 6356.25

SP = 5625

Now SP was after 10% discount on Original Price, say MP. So:

0.9 * MP = 5625

MP = 6250

Therefore, the percent of Marked Price above Cost Price is:

(6250 - 5000) * 100/5000 = 25%
