F(-1)=-3
F(2)=-3/2
F(0)=-2.5
F(9)=2
Answer:
Step-by-step explanation:
4x + 23 + 9x - 38 = 180
13x - 15 = 180
13x = 195
x = 15
4(15) + 23= 60 + 23= 83
9(15) - 38 = 135 - 38= 97
21y - 1 + 97 = 180
21y + 96 = 180
21y = 84
y = 4
21(4) - 1 = 84 - 1 = 83
The answer is 0.003, because the two "00" in front of the three represent, tenths and hundredths, and the 3 is in the thousandths place<span />
Y-y(1) = m(x - x(1))
y - 1 = (-3/4)(x + 8)
