Answer:

Allentown(x) got 8 feet of snow and Georgetown(y) got 3 feet of snow

Step-by-step explanation:

Allentown got 2 feet less than twice the amount of snow Georgetown got . Allentown got 3 feet more snow than Georgetown.

Allentown = x     and  Georgetown=y

To solve this we need to represent this information mathematically;

'Allentown got 2 feet less than twice the amount of snow Georgetown got' can be written mathematically as;    x = 2y - 2

and

'Allentown got 3 feet more snow than Georgetown' can be mathematically written as x = y + 3

x=  2y  -  2  ----------------------(1)

x = y + 3  --------------------------(2)

Subtract equation (2) from equation (1)

[ x-x=0          2y-y = y          -2-3=-5]

0 = y  - 5

To get the value of y, add 5 to both-side of the equation

0+ 5  =  y-5+5

5=y

y=5

Substitute y=5 into equation (2)

x = y+3

x=5+3

x=8

Therefore Allentown(x) got 8 feet of snow and Georgetown(y) got 3 feet of snow

x=2y-2

x=y+3

Substitute the second equation into the first

y+3=2y-2

solve for y

y=5

plug into original

x=y+3=5+3=8 or x=2(5)-2=8

Allentown got 8 ft of snow, Georgetown got 5 ft of snow.

Answer:

= 4n - 2

Step-by-step explanation:

There is a common difference d between consecutive terms in the sequence, that is

6 - 2 = 10 - 6 = 14 - 10 = 18 - 14 = 4

This indicates the sequence is arithmetic with n th term

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 4 , thus

= 2 + 4(n - 1) = 2 + 4n - 4 = 4n - 2

The value of (goh)(3) is 26.

What is composition of function?

The composition of a function is an operation where two functions say f and g generate a new function say h in such a way that h(x) = g(f(x)).

given:

g(x) = 2x , h(x) = x²+4

Now,

(goh)(3)

=g(h(3))

=g(9+4)

=g(13)

=2*13

=26
