$2r = 17 + s = 50 - 2s \\ 3s = 50 - 17 = 33 \\ s = 11 \\ \\2 r = 50 - 2s \\ 2r = 50 - 2 \times 11 = 50 - 22 = 28 \\ r = 14$

C. r=14, s =11

Mazyrski [523]

Answer:

$x^2$

Step-by-step explanation:

apply the inverse properties of logarithmic and exponential functions to simplify

$ln(e^{x^2})$

all logs has base 'e'

Inverse property of log says that

$ln(e^x)=x$ , the value of ln e=1

we apply this property in our problem. ln has same base 'e' . ln and 'e' gets cancelled

$ln(e^{x^2})$

$x^2$

I need help with this question

k0ka [10]

F(x) = 1 / (x - 2)...when x = 4
f(4) = 1 / (4 - 2)
f(4) = 1/2 <==

f(x) = 1 / (x - 2)...when f(x) = 1
1 = 1 / (x - 2) ...multiply both sides by (x - 2) eliminating it on the right
1(x - 2) = 1
x - 2 = 1
x = 1 + 2
x = 3 <==
