I think it's 1.90. I am not fully sure about the answer if it's wrong.
Answer:The answer would be A) blue
Step-by-step explanation: The blue segment represents the measurement of the part of a circle
Answer:
b=4a
Step-by-step explanation:
In both cases, we have cooling. We can add together the 2 functions describing this cooling: z(x) = 0.5x - 9 - [-x-2] = 0.5x - 9 + x + 2, or
z(x) = 1.5x - 7
Provided that this is correct, all we have to do now is to subst. 5 for x:
z(5) = 1.5(5) - 7 = 7.5 - 7 = 0.5 (answer)
-(50x-15y+15) = -50+15y-15
