Which function is the inverse of f(x) = 2x+37

Mathematics
1 answer:
WINSTONCH [101]3 years ago
3 0

Answer:

f^{-1} (x)=\frac{x-3}{2}

Step-by-step explanation:

y = f(x)

y = 2x+3

You need to switch the places of x and y, into this:

x = 2y + 3

Then solve for y:

2y = x-3

y=\frac{x-3}{2}

f^{-1} (x)=\frac{x-3}{2}

How many equilateral triangles with sides of 4 can fit into a larger triangle with sides of 2012
igomit [66]
The base measures 2012 if you divide that by four you get 503 trianles on the bottom and on the sides and each one gets one smaller until you get to one so 503+502+501,.... or 252+251(504) so the answer is 126,756 triangles in total because 1+503=504  2+502=504... when you get to 252 you just add that to itself so that is the odd one out

Jack bought 4 bagels for $3.00.How many bagels can he buy for $4.50?
nydimaria [60]

Answer:

He can buy 6 bagels.

Step-by-step explanation:

In order to figure out how much each bagel is, you need to divide $3.00 by 4. This gives you .75 because 3.00/4=75. Each bagel is therefore $0.75. Now, in order to find how many bagels you can buy with $4.50, you have to divide 4.50 by 0.75. The equation is 450/75=6. You can buy 6 bagels with $4.50.

Let me know if you need any more help. Have a nice day. :)
