BD = BC + CD
7x - 10 = (4x - 29) + (5x - 9)
7x - 10 = 9x - 38
2x = 28
Ans: x = 14
BC = 4x - 29
= 4(14) - 29
= 27
Ans: BC = 27
CD = 5x - 9
= 5(14) - 9
= 61
Ans: CD = 61
BD = 61 + 27
= 88
Ans: BD = 88
Change of y / over change of x
Go over 4, up 45
B is your correct answer
Hope this helps!
Quadrant one is not the answe but I think it’s 5x
The answer is C
the domain is the x values which would be {1,2,3,4,5} and the range is the y values which would be {6,7,8,9}
if this helped please give brainliest!
