5. write an equation in slope intercept form for the line parallel to : y=5x-2 that passes through (8, -2).
6. find the X and Y intercepts of -x+2y=8
7. solve the graph: 1<3x-2≤10
10. how many miles did she hike if she hiked for 1.75 hrs at a speed of 3.5 mi/h ?
31. the first term of geometric sequence is 512 and the common ratio is 0.5 what is the 8th term of the sequence?
37. find the slope and the Y intercept: 14x+4y=24
32. the fish population of lake henry is decreasing at a rate of 4% per year. in 2002 there were about 1,250 fish. write an exponental decay function to model this situation then find the population in 2008.
36. solve the inequality: 12+10w⪰8(w+12)
26. identify the excluded value for the rational function: y=5/x +1
27. simplify the rational expression: x-3/x^2-5x+6
28. (x+2/4x-8)(3x-9/x+4)(2x-21/x^2-x-6)
29. divide: m^2+10m+24/m+4
24. mom likes to serve 2 diff. kinds of vegetables with dinner. she has carrots,peas,okra, and green beans in her refrigerator. how many diff. sets of 2 vegetables can she serve? tell whether the situation is a combination or a permotation.
21.solve quadratic equation: x^2+2x-8. by factoring
22.complete the square for x^2-14x+___ ? to form a perfect square trinomial
19. golfer hits the ball. the quadratic function y= -16x^2+80x gives the time x seconds when the golf ball is at height 0 ft. how long does it take for the golf ball to return to the ground
20. use the zero product property to serve the equation (x+4)(x-3)= -10
6. X= -8 Y= 4
22. +49
21. (x-4)(x+2)
29. use sintetic division- answer would be m+6
37. slope is 7/2 and y intersept is 6
7. you add 2 to both sides first then divid by 3 than you graph
