Answer:
1x + 4y = 4 ⇒ 6x + 24y = 24
6x - 8y = 0 ⇒ 6x - 8y = 0
32y = 24
32 32
y = 3/4
x + 4(3/4) = 4
x + 3 = 4
-3 -3
x = 1
(x, y) = (1, 3/4)

If the person walks on the inside edge, he will walk the perimeter of the park.
Solution: 2(245) + 2(420) = 490 + 840 = 1330 yards
Answer:
Step-by-step explanation:
<u>1)</u>
f(x) = -6x + 3
To get the inverse of this, make x be the subject of the formula.
let f(x) = y
6x = 3 - y
x = (3 - y)/6
∴ f(x) = (3 - x)/6
Truly f and g are inverse functions.
<u>2)</u>
f(x) = -3x²+ 5
let f(x) = y
y = -3x² + 5
3x² = 5 - y
x² = (5 - y)/3
x = √[(5 - y)/3]
f(x) = √[(5 - x)/3]
Truly f and g are inverse function.
