Answer: The value of g(3) = 7

Step-by-step explanation:

The given function : g(x) = 2x + 1.

We know that to calculate the value of f(a), where f(x) be any function , we need to substitute the value of x=a in the function.

To calculate the value of g(3) , we need to substitute the value of x=3 in the above function , we get

g(3)=2(3)+1\\\\\Rightarrow\ g(x3=6+1\\\\\Rightarrow\ g(3)=7

Therefore, we get the value of g(3) = 7

(Geometry), homework please help

Exercise 1:

The angle in the low left corner is supplementar with the external angle. Since the external angle is 105, the inner angle is 75.

Since in every triangle the inner angles sum to 180, we have

x = 180-75-72 = 33


Exercise 2:

Again, you need to use the fact that in every triangle, the sum on the inner angles is always 180.


Exercise 3:

Since PQ and BC are parallel, triangles APQ e ABC are similar. This means that their side are in the same proportion, so


AP : AB = AQ : AC


Plug the known values of AB, AP and AC and solve for AQ:


6: 12= AQ : 18 \implies AQ = \frac{6\cdot 18}{12} = 9

The school that Alberto goes to is selling tickets to a fall musical. On the first day of ticket sales
vaieri [72.5K]

Answer:

<em>The price of both tickets is $12 each</em>

Step-by-step explanation:

<u>System of Equations</u>

Let's call:

x = price of a senior citizen ticket

y = price of a child ticket.

On the first day of ticket sales, the school sold 6 senior citizen tickets and 2 child tickets for $96. Setting up the first equation:

6x + 2y = 96

Dividing by 2:

3x +  y = 48         [1]

On the second day, the school sold 6 senior citizen tickets and 4 child tickets for $120:

6x + 4y = 120

Dividing by 2:

3x + 2y = 60         [2]

Subtracting [2] and [1]:

2y - y = 60 - 48

y = 12

From [1]:

3x +  12 = 48

3x = 48 - 12 = 36

x = 36/3 = 12

x = 12

The price of both tickets is $12 each
