Answer:
The length of the rectangle is 25 km
Step-by-step explanation:
Let
x ----> the length of rectangle
y ----> the width of rectangle
we know that
The perimeter of rectangle is
we have
so
simplify
---- > equation A
---> equation B
substitute equation B in equation A and solve for y
Find the value of x
therefore
The length of the rectangle is 25 km
Answer:
( - , - )
Step-by-step explanation:
Given the 2 equations
8x = 2y + 5 → (1)
3x = y + 7 → (2)
Rearrange (2) expressing y in terms of x by subtracting 7 from both sides.
y = 3x - 7 → (3)
Substitute y = 3x - 7 into (1)
8x = 2(3x - 7) + 5 ← distribute and simplify right side
8x = 6x - 14 + 5
8x = 6x - 9 ( subtract 6x from both sides )
2x = - 9 ( divide both sides by 2 )
x = -
Substitute this value into (3) for corresponding value of y
y = 3 × - - 7 = - - = -
Solution is (- , - )
Answer:
(x+9)(x+2)
Step-by-step explanation:
x(x+9)+2(x+9)
(x+2)(x+9)
the order of the (---) doesn't matter
The inverse of this would be
f^-1(x) = -7/4 + x/4
