Answer:
80
Step-by-step explanation:
From the given diagram;
KN = NM
9x - 5 = 7x + 7
9x - 7x = 7 + 5
2x = 12
x = 12/2
x = 6
Since KM= 2KL
KM = 2(6x+4)
KM = 12x + 8
KM = 12(6)+8
KM = 72+8
KM = 80
Hence the length of KM is 80
3750(0.20)=$750
1/5 as a percent is 20% and as a fraction it is 0.20
Multiply 120 by 18%
Change 18% to a decimal: 0.18
120 x 0.18 = 21.6
Answer: 21.6
Answer:
f(3) = -4
Step-by-step explanation:
Draw a line parallel to the y-axis and cross point 3 on the x-axis. This line cuts the parabola at a point whose coordinates on the y-axis are f (3). This is -4.
Hope you understand.
