Answer:
answer: 1) false 2) true 3) true 4) false
Step-by-step explanation:
A: pass (0,0) (12,6)
slope: 6/12 = 1/2
y = 1/2 x
x=1 y= 1/2
B: pass(0,0) (4,6)
slope: 6/4 = 3/2
y = 3/2 x
y=1 x= 2/3
Answer: The answer here is x=12.49
Step-by-step explanation:
The idea is tho remove the brackets on the right hand side by multiplying by 4.9
4.90= 10(x-12)
4.90=10x-120
x=12.49
Answer:
No, 40(2x - 16y) is not equivalent to 42 - 56y
Step-by-step explanation:
40(2x -16y)
If we expand the above expression, we will have
80x - 16y which is not equivalent to 42 - 56y
Answer:
326.56 square feet
Step-by-step explanation:
Surface area of a cylinder = 2πrh + 2πr²
Radius = Diameter/2
= 8 ft/2
= 4 ft
Height = 9 ft
Surface area of a cylinder = 2πrh + 2πr²
= (2 * 3.14 * 4 * 9) + (2 * 3.14 * 4²)
= 226.08 + 100.48
= 326.56 square feet
Surface area of a cylinder = 326.56 square feet
Answer:
+2 each year. 40+(2+y), y being years.
