If the coefficient of x^2 is negative, the graph will be n shaped and curve down instead of like a u shape if it was positive. If the vertex is below the x axis and curves down, it won’t pass the x axis, Tia is right.
10^-8 would be .000000001 I believe lightning would be the correct answer because .00000001 is bigger than 10^-8 hope this is correct
9x–42=5 is x = 11.
<u>Step-by-step explanation:</u>
9x- 42 = 5...
When we put x = 9
then we will get 81 - 42 =39
put x = 10 then
9(10) - 42 = 90 - 42 - 48
put x = 11
then 9(11) - 42 = 99-42 = 57
So x = 11 is the answer.
The Answer is: 4.73
34.14 - 5.76
