A bank loaned out $31,000, part of it at the rate of 13% annual interest, and the rest at 4% annual interest. The total interest earned for both loans was $2,770.00. How much was loaned at each rate? $was loaned at 13% and

$was loaned at 4%

heyyy

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

i believe that the slope of the line is -5
