Archers need to use arrows that do not bend easily. The table shows how the weight of an arrow affects its spine or the distance the center of the arrow bends when a certain constant weight is attached. Graph the data in the table to find a linear and quadratic model for the d...

Steve can you recheck my answer

this is what i got y=39 x=-117 y when x=-132 39/-117=k k=-0.3 y=-0.3*-132 y=39.6

algebra
so should be 39.6

algebra
oh ok thanks for catching my mistake

algebra
Find the value of y for a given value of x, if x varies directly with x. If y=39 when x=-117 what is y when x=-132 my answer y=k*x 39=k*-117 39/-117=k k=-0.3 y=k*x y=-0.3*-1.32 y=-3.96 can someone please check my work

algebra
not sure they are in possible answers

what is the simpler form of the radical expressio. 4 sqrt 2401x^12y^16 I know its 7x^3y^4 but not sure if looks like 7[x^3[y^4 7x^3[y^4

algebra
would the answer be 2 3sqrt 6 + 9 3sqrt18 over 6

algebra
how can you write the expression with rationalized denominator? 2+3sqrt3/3sqrt6
