Answer:
129
Step-by-step explanation:
If three lines CD, CE and CF extend from point C, then the following addition postulate is true;
<DCE + <ECF = <DCF
If the space between line C D and C E is 75 degrees, then <DCE = 75
If the space between lines C E and C F is 54, then <ECF = 54.
Substitute the given values into the expression above will give;
<DCF =<DCE + <ECF
<DCF = 75+54
<DCF = 129
Hence the measure of <DCF is 129°
From the given step function in this item above, we can see that the value of y in the given equation is dependent in the values of x but with certain step-wise arrangement. As we can see, for x = 1, the value of y is equal to 0. Thus, the answer is the first choice.
Answer:
D)
Step-by-step explanation:
No, a reasonable estimate is around 9. $6 = $54
I got it right on my test
6.333333 repeating decimal because 1/3 is infinite and cannot be evenly divided.
