Answer:
Let price of drink be x
price of tub y
You have 4x+2y=32.5 (1) and
x = y -3.5 (2)
Plug for x from (2) into (1):
4(y-3.5) + 2y = 32.5
4y -14 +2y = 32.5
6y = 14+32.5
y = (46.5)/6 = $7.75 the price of tub
x= y-3.5 = 7.75 - 3.5 = $4.75
Assuming you are talk about a quadratic with y=-x^2-6x-13
Domain is all reals
Answer:
351π cm^2.
Step-by-step explanation:
Area of shaded part = area of the large circle - area os small circle
= π * (13+7)^2 - π * 7^2
= 400π - 49π
= 351π.
