Answer:
(-a-b,c)
Step-by-step explanation:
midpoint D : ((-2b-2a)/2 ;(2c+0) /2 )
(-2b-2a)/2 = 2(-b -a)/2 = -b-a
(2c+0) /2 =2c/2 = c
Answer:
Δ MNO ≅ Δ RST
Step-by-step explanation:
In naming the congruent triangles follow the same order, that is
M is the vertex with 79° and R is the vertex with 79°
MN = 21 and RS = 21
These are the first 2 letter names of the triangles, that is MN and RS
O and T are the third, thus
Δ MNO ≅ Δ RST
Answer:
Shad's cost per use will be $ 2.80.
Step-by-step explanation:
Since Shad Yarbrough wants to consider the cost per use of a high-end desk top computer he is considering for his web site business, and the computer costs $ 1,750 and has a life expectancy of four years, if Shad feels he would use the computer three days a week, on average, to determine what is Shad's cost per use, the following calculation must be performed:
Weeks per year = 52
52 x 4 = 208
208 x 3 = 624
1750/624 = X
2.80 = X
Thus, Shad's cost per use will be $ 2.80.
Of course A does because integers are positive and negative
