(x, y) = ( ,
)
given the 2 equations
5x - 3y - 10 = 0 → (1)
x + y - 7 = 0 → (2)
rearrange (2) to obtain y in terms of x
y = 7 - x → (3)
Substitute y = 7 - x into (1)
5x - 3(7 - x) - 10 = 0
5x - 21 + 3x - 10 = 0
8x - 31 = 0 ( add 31 to both sides )
8x = 31 ( divide both sides by 8 )
x =
Substitute this value into (3) for y
y = 7 - x = -
=
Answer:
No you do not.
This is because we can use Pythagoras Theorem to show that our location sits outside the 15 mile radius of the cell tower.
To work is out you would write the equation
Then to work out the Hypotheses you would
Which proves that the location is outside of the 15 Mile radius of the cell tower.
Answer:
Step-by-step explanation:
Surface area of a cylinder:
S. A. = 2πrh + 2πr²
Volume of a cylinder:
V = πr²h
~~~~~~~~~~~
2(π)(2.5)(x) + 2(π)(2.5)² = π(2.5)²(x)
5x + 12.5 = 6.25x
1.25x = 12.5
x = 10
