Answer:
B
{(8,-9), (-8,-5), (8-7), (-8,-6)}
Step-by-step explanation:
A function can have two X values but not two Y values

Notice that the second row is half the first, so the rows are dependent. This means there are infinitely many solutions to the system.
The spherical container has a radius of 4ft (where ft represents feet)
Its filled with gas that costs $12 per ft³
The value of gas in the container = ?
The volume of a sphere = 4/3
r³
The volume of the container = 4/3 ×
× 4³ ft³
One cubic foot = $12
4/3 ×
× 64 = How much?
Cross multiplying gives:
4/3 ×
×64 × $12 = $3216.99 (Rounded up to nearest one cent)
Answer:
4
Step-by-step explanation:
2 · 4 = 8
8 + 4 = 12
the value of x is 4
<span>Differentiating :
y' = 1 + sec^2(x),

cosπ=−1</span><span>
plug in pi = -1 ,for x:
1 + sec^2(pi) = 1 + (-1)^2
= 2</span>
