Answer:
Well, they both involve math, and a word problem uses a equation to tell the problem.
Step-by-step explanation:
Answer is B 1, -1
y = -2x + 5
when x = 2; y = -2(2) + 5 = 1
when x = 3; y = -2(3) + 5 = -1
Answer:
The answer is 2x + y - 3z
Step-by-step explanation:
∵ 
∵

∵ 


∴ 2x + y - 3z
Answer:
Line CDE is a straight line,
so 85°+70°=55°
180°-55°=25°
angle BDA=25°
25°+85°=110°
180°-110°=70°
angle CDF=70°
