Answer:

(5,-3)

Step-by-step explanation:

y+3 = 3x-15

y= -2x + 7

plulg y in

-2x+7+3 = 3x-15

combine like terms

-2x+10 = 3x-15

add 2x to both sides and add 15 to both

5x=25

x=5

y=-2(5) +  7

y= -10 + 7

y= -3

If(x)= 2e^x-1 +3 , what is f^-1 (x)
Rainbow [258]

Answer:

f^-1 (x) =  1+ln( (x-3)/2)

Step-by-step explanation:

hello :

let f(x) = y  so : y = 2e^(x-1) +3

calculate x :  e^(x-1) = (y-3)/2

for : y-3 > 0 :  x-1 = ln( (y-3)/2)    so : x= 1+ln( (y-3)/2)

If(x)= 2e^(x-1) +3 , what is f^-1 (x) =  1+ln( (x-3)/2)

Can someone please help me with this question
Elina [12.6K]

Answer:

The answer should be: B

I think it's B because there are 2 cups of water (2c) and 7 bottles of water (7w) which costs $16 so that would be 2c +7w=16. Also for the other one, it's 3 cups (3c) and 8 bottles of water (8W) and the cost is $19 so that would be

3c + 8w =19

Step-by-step explanation: Hope this helps and gl :))
