Answer:
X = 74°
Step-by-step explanation:
90 + 30 = 120 (S + T = 120 )
180 - 120 = 60 (triangles total - S and T's Total = U )
120 - 46 = 74 (The angle TUX is 120 so the answer is 74)
Really hope I did this right and sorry if not
The vector equation of the line through the origin perpendicular to the plane is
.. (x, y, z) = t(2, 3, -1)
so the point of interest will satisfy
.. 2(2t) +3(3t) -(-t) = -3
.. 14t = -3
.. t = -3/14
and its coordinates are (x, y, z) = (-3/7, -9/14, 3/14)
Answer:
choice 2) x+2y+3 = 7
Step-by-step explanation:
equation to match:
x+2y = 4
add 3 to each side
x+2y+3 = 7 (which is the same as choice 2, x+2y+3 = 7)
Answer:
Step-by-step explanation:
The formula for the sum of n terms of an arithmetic sequence is
aₙ = a₁ + (n-1)d
If a₁ = -40, d = -7, and n = 22
