Use a graphing calculator to sketch the graph of the quadratic equation, and then state the domain and range. y = negative 5 x squared + 3 x + 10 a. D: (x greater-than-or-equal-to 0.3) R: all real numbers c. D: (x greater-than-or-equal-to 0.3) R: (y less-than-or-equal-to 10) b. D: all real numbers R: (y greater-than-or-equal-to 10.45) d. D: all real numbers R: (y less-than-or-equal-to 10.45) Please select the best answer from the choices provided A B C D

step-by-step explanation:

if x = 2 you have to find x to finish the problem

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

step-by-step explanation:

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
