Answer:
(42, 21) or (–42, –21)
Step-by-step explanation:
let A(x, y), A on line 2y = x
distance
x² + y² = 2205
(2y)² + y² = 2205
y² = 441
y = ±21
x = ±42
0.07 (5000-x) + 0.15x= 480
Solve for x
350-0.07x+0.15x=480
0.08x=130
X=1625 invested at 15%
(5000-1625)=3375 invested at 7%
She harvested 93 kg of apples.
First you need to set it up like this:
X/75=24/100
Then you cross multiply and get:
1800=100x
The you isolate the variable (divide both sides) and get 18
75+18=93
