D. y = 9 because it has a complete zero slope while the y-intercept of the equation is 9, so the equation is y = 9.
7x +16 < -5(4 - 5x)....given
7x + 16 < -20 + 25x....distributive property
16 < -20 + 18x ... subtraction property
16 + 20 < 18x.....addition property
36 < 18x
36/18 < x.....division property
2 < x
The answer is 5900 as 879 in 5000 is closer to 900 rather than 800.
Well all u have to do is minus -6 from 23 so 23-6 is 17. Then all u have to do is add 0+17 so ur answer is the temperature changed 17 F
