A new hard drive costs $225, plus $40 per hour for labor. The linear equation y=40x + 225 gives the cost y in dollars for x hours of labor. If Jane has $385 to spend on computer repairs, what is the maximum number of hours the computer technician can work? *

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?

Simplify the expression. -2/5(10+15m-20n)

X^2/100+y^2/25=1 the y-intercepts are at: a) (-10,0) and (10,0) b) (0,10) and (0,5) c) (0,-5) and (0,5)
