Answer:
a,c,d and e are TRUE.
Step-by-step explanation:
<8 and <5 add upto 180°(supplementary)
<4 and <7 are angles outside and opposite of the transversal(the line that is crossing the parallel lines)
<5 and<7 are 90°(vertical)
<2 and<6 are on the same side of the transversal(corresponding)
F(x) = -2.5x + 135...where x is the number of weeks, and f(x) = total weight
Answer:
a= 13+3b
Step-by-step explanation:
Simplifying
a + -7 = 3(b + 2)
Reorder the terms:
-7 + a = 3(b + 2)
Reorder the terms:
-7 + a = 3(2 + b)
-7 + a = (2 * 3 + b * 3)
-7 + a = (6 + 3b)
Solving
-7 + a = 6 + 3b
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + a = 6 + 7 + 3b
Combine like terms: -7 + 7 = 0
0 + a = 6 + 7 + 3b
a = 6 + 7 + 3b
Combine like terms: 6 + 7 = 13
a = 13 + 3b
Simplifying
a = 13 + 3b
