If y=-x2+14x+7, then x=10 is a counterexample for which conjecture? a. y is always positive. b. y is always negative. c. y is a function of x. d. the graph of y is a parabola.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

step-by-step explanation:

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation
