Answer:
f(x) = 3x +5
Step-by-step explanation:
The x-values change by 1 from the first line to the second.
The y-values change by -13-(-16) = 3 from the first line to the second.
Then the "rate of change" is ∆y/∆x = 3/1 = 3. This will be the coefficient of x in the equation. The last choice is appropriate:
f(x) = 3x + 5
Answer:
b. 106 sq.cm
Step-by-step explanation:
A=L×W
A1= 2(5×8) = 2(40) = 80
A2= 2(1×8) = 2(8) = 16
A3= 2(5×1) = 2(5) = 10
Total area = 80 + 16 +10 = 106 sq. cm
40% of 120 is 48
1/4 of 200 is 50
1/4 of 200 is bigger.
