When you calculate (ln) 7, you would be finding the value of which of the following expressions? log_e 7
log_7 10
log_10 7
log_7 e

log_e (7)

Step-by-step explanation:

(ln) 7,

ln stands for natural log, which is log base e

log_e (7)

77

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
