Step-by-step explanation:
Hi :)
Let x be the amount invested at 7% and y the amount invested at 6%
We know that the yearly interest earned = 0.07(x) and 0.06(y)
x+y =4500
0.07x +0.06 y =290
Solving the equations will give , x = $2,000 and y=$2,500
M=3n
divide both sides by 3
M/3=3n/3
on the left hand side, the numerator constant cuts the denominator 3
therefore, n=M/3
Step-by-step explanation:
General equation : y = mx + c
2y - 4x = 2
2y = 4x + 2
y = 2x + 1
Therefore m = 2 and c = 1.
