In the chart of the triangle it shows that the variable b is the base. It also give us the equation for area 1/2bh (half of base * height)
Now we just plug in the values we are given
1/2bh
1/2(10*13)
1/2(130)
65
The area of the triangle is 65 ft
Answer:
y = 2x+10
Step-by-step explanation:
y is the cost (which we don't know)
2x is the $2 per card with x representing the number of cards (which we don't know)
And of course 10 is the cover charge.
Start at (0, 135) and work your way down 15 and over one each time. Your next point would be (1, 120)
we know that

so
by proportion
