Answer:
m=-4 slope is -4
Step-by-step explanation:
Finding an angle of a triangle
Xd = y(L-d) then divide by "y"
xd/y = L - d then add "d"
xd/y + d = L
Answer:
8n=20+6(n-2)
Step-by-step explanation:
n is the number of GB
Plan A has no initial fee and charges 8$ per each GB
So A has an equation that is y=0+8n or just y=8n.
Plan B has 20 for the first 2 GB and $6 for each addition GB after the first 2.
So B has an equation that is y=0+20+6(n-2) assuming n is 2 are greater.
So the two equations are y=8n and y=20+6(n-2).
We want Plan A to be the same as Plan B.
So we need to solve:
8n=20+6(n-2).
Let's check our equation:
Distribute:
8n=20+6n-12
Subtract 6n on both sides:
2n=20-12
2n=8
Divide both sides by 2:
n=4
Plan A charges 8 dollars ber GB, so plan A charges 4(8)=32 dollars.
Plan B charges 20 dollars for the first 2GB and 6 dollars for each GB after so we used 4 which means we are spending 20+6(2)=20+12=32 dollars.
They are the amount so n=4 is right.
