Answer:
1) 8 2) -33/9
Step-by-step explanation:
1) (1/2)x = -1/2 + 9/2
(1/2)x = 4 x = 8
2) distributing 3/2, 9x/2 - 15/2 = -24
9x/2 = -24 + 15/2
9x/2 = -33/2
9x = -66/2
9x = -33
x = -33/9
1) <span>Pairs A(2, 5), B(6, 5), and C(6, 1)
point D
Dx=Cx-(Bx-Ax)=(6-(6-2))=2
Dy=Cy=1
</span>the coordinates of vertex D is (2,1)
2) Pairs <span>A(2, 3), B(7, 3), and C(7, -2)
</span>point D
Dx=Cx-(Bx-Ax)=(7-(7-2))=2
Dy=Cy=-2
the coordinates of vertex D is (2,-2)
3) Pairs <span>A(-5, -1), B(1, -1), and C(1, -5)
</span>point D
Dx=Cx-(Bx-Ax)=(1-(1+5))=-5
Dy=Cy=-5
the coordinates of vertex D is (-5,-5)
4) Pairs <span>A(-1, 4), B(7, 4), and C(7, -1)
</span>point D
Dx=Cx-(Bx-Ax)=(7-(7+1))=-1
Dy=Cy=-1
the coordinates of vertex D is (-1,-1)
The cotangent function can be obtained by taking the reciprocal of the tangent of the same angle. Using a calculator, taking the tangent of 10 degrees and taking the reciprocal of the answer would yield the correct one. With that, the correct answer would be D.) 5.671.
Answer:
She bought six first class tickets.
Step-by-step explanation:
360 × 4 = 1,440
1140 × 6 = 6,840
1,440 + 6,840 = 8,280
hope this helps :)
