Y=-1/4x+13 not sure though
For something to be a function, each input (x value) can only have ONE output (y value)
If an input has multiple outputs, it is not a function.
so the last graph represents a function (parabola going down)
Complete Question
Talia attended a 5 -day math camp that lasted 5/6 of an hour each day. How many hours did Talia spend at the math camp?
Answer:
4 1/6 hours
Step-by-step explanation:
1 day = 5/6 hour
5 days = x
Cross Multiply
x = 5/6 × 5 days
x = 25/6 hours
x = 4 1/6 hours
Therefore, Talia spent 4 1/6 hours at camp.
Answer:
Step-by-step explanation:x+y+z=100(let x ,y,z represent the first second and third numbers respectively)
Therefore,y=2z
z=x-8
y=2x-16
substituting the values of x,y and z into the question,we have
x+(2x-16)+(x-8)=100
Simplifying,we have
4x-24=100
adding 24 to both sides of the equation,
4x=100+24
4x=124
dividing both sides of the equation by the co-efficient of x,we have
4x/4=124/4
4.31=124
therefore,x=31.
