Answer:
(-2/7, 2/3)
step-by-step explanation:
-7x + 3y = 2
x = 0
-7(0) + 3y = 2
3y = 2
/3 /3
y = 2/3
y = 0
-7x + 3(0) = 2
-7x = 2
/-7 /-7
x = -2/7
(-2/7, 2/3)
Question 10
30-2=28
28*2= 56
56*2= 112
120*2= 240
240+112=352.
Area = 352 square feet
Question 11
Volume = pi*r*r*h
=3.142*2.5*2.5*0.5
= 9.817
From the choices the answer is
D. 9.8 cubic ft
The inequality is :
4 + x > 6
