Write an equation for the relationship shown on this graph if the price per ticket is doubled.​
vlabodo [156]

Answer:

y = 2x

linear equations are just finding the right ratio and putting it in y = mx+b format

this graph is saying that two dollars are earned for every ticket sold, a 2:1 ratio.

so the equation would be y = 2x, two being the amount of money collected for one ticket, and x being the number of tickets sold.

Which equation is an identity?
dalvyx [7]

The condition for an expression to be an <u>identity </u>is that both sides of equality must give the same value.



In this case, the equation that fulfills that condition is the first equation (1).



<u>Let’s prove it:</u>


1) 3w+8-w=4w-2(w-4)



Applying distributive property:



3w+8-w=4w-2w+8



Joining together similar terms on both sides of the equality:



2w+2w-4w=8-8



<h2>0=0    >>>>>>>This is true and fulfills the condition of identity</h2>

The other equations do not fulfill the condition:


2) 5y+5=5y-6


5y-5y=-6-5


0 =-11   >>>>>>>This is not logic



3) 6m-6=7m+9-m


6m-7m+m=9+6


0=15  >>>>>>>This is not logic



4) 8-(6v+7)=-6v-1


8-6v-7=-6v-1


1=-1   >>>>>>>This is not logic
