7x - 9 = 28 + 4x - 4
7x - 4x = 28 - 4 + 9
3x = 33
x = 11
-2x + 3y = 12
x intercept y = 0
-2x = 12
x = -6
y intercept x = 0
3y = 12
y = 4
answer
y intercept (0,4)
x intercept (-6,0)
Simple interest formula:
Interest = P*R*N
P = principle amount
R = interest rate (in decimal)
N = number of time periods (in years)
Interest = 5000*0.05*4 = $1000
Question two simplified is this :)
