Determine wether each equation is linear or not. then graph the equation y finding and plotting ordered pair solutions. show work. (hint: let x=-3, -2, -1, 0, 1, 2) 27. x+y=3 28. y-x=8 29. y=4x 30. y=6x 31. y=4x-2 32. y=6x-5 33. y=|x|+3 34. y=|x|+2 35. 2x-y=5 36. 4x-y=7 37. y=2x^2 38. y=3x^2 39. y=x^2-3 40. y=x^2+3 41. y=-2x 42. y=-3x 43. y=-2x+3 44. y=-3x+2 45. y=|x-2| 46. y=|x-1| 47. y=x^3

Step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
