Answer:
<u>Algebraically</u>
0.5x-7= √(-5x+29)
(0.5x-7)² = -5x+29
(0.5x)² - 2*0.5x*7 + 7² = -5x+29
0.25x² - 7x + 49 + 5x - 29 = 0
0.25x² - 2x + 20 = 0
Its discriminant is:
b² - 4*a*c
(-2)² - 4*0.25*20
-16 < 0
Therefore, the equation has no solutions.
<u>Graphically</u>
In the picture attached, the plots of the functions are shown. We can see that they don't intersect each other, and that is why there is no solution.
It’s a function if it passes the vertical line test or pencil test. Using a pencil and following the function if it touches the pencil in more then one spot it is not a function.

Sixty times ten to the seventh power = <span>600,000,000 six-hundred million
eighty-six times ten to the sixth power =</span>86,000,000 eighty-six million
nineteen times ten million = 190,000,000 one-hundred ninety million
Answer: She divided 30 by 1/10, Then rather than putting 300 down as the answer She put 1/10.
Step-by-step explanation: if you divide 30 by 1/10 you get 300, She may have put 1/10 because you need to put fractions in the blank squares.
