If the question is how many students are girls, than it's ten(10).
Answer:
D) -122
Step-by-step explanation:
Given:
We need to find f(-4).
Now by substituting the value of x =-4 in above equation we get;
By using PEDMAS we will solve for exponential function first we get;
Now we know that 
So we get;
Now using PEDMAS we will solve division.
Now using PEDMAS we solve multiplication.
Finally by subtraction we get;
Answer:
DF = 14
Step-by-step explanation:
Andrew was wrong in the assumption that DE = EF
Segments of tangents to a circle from the same external point are congruent
That is
EF = FG = 8
Then
DF = DE + EF = 6 + 8 = 14
Answer:
17. xy + z = 51
18 yz - x = 18
21. 5z + ( y - x ) = 20
22. 5x - ( y2 - 4x ) = -10
23 . x2 + y2 - 10z = 70
24. z3 + ( y2 - 4x ) = 1
25. y + xz / 2
26 .3y + x2 / z = 30
Step-by-step explanation:
17.(6 x 8)+3=
48+3=51
18.(8 x 3)- 6 =
24 - 6 = 18
21. 15 + ( 8 - 3 )
15 + 5=
20
22 .30 - (64 - 24)=
30 - 40=
-10
23. 36 + 64 - 30
100 - 30
70
24. 9 + (16 - 24 )=
9 + -8 =
1
25. 8 + 48 / 2
56 / 2
28
26. 24+ 36/3
60/3=
30
