20 ! will mark brainliest for the best ! use the given information about the polynomial graph to write the equation. degree 5. roots of multiplicity 2 at x=3 and x=1, and root of multiplicity 1 at x=3 and x=-2. y=intercept at (0,9)

15 points! write the slope-intercept form of the equation of the line through the given point with the given slope. use y-y = m(x-x) to solve. through (2,5) slope= undefined

For what values of the variable x is the expression square root of 7x+14+ square root of 7-x a real number?

Twelve different video games showing substance use were observed and the duration times of game play (in seconds) are listed below. the design of the study justifies the assumption that the sample can be treated as a simple random sample. use the data to construct a 99% confidence interval estimate of μ, the mean duration of game play. 4028 4316 4816 4650 4036 5010 4833 4331 4307
