Answer:

64 adult tickets were sold and 36 children tickets were sold

Step-by-step explanation:

i created two equations. 7A + 4C = 592 and A + C = 100. A stands for adult tickets and C stands for children tickets. in order to find the value of C, the children tickets, i took the second equation, A + C = 100, and subtracted A on both sides to get C = -A + 100. i then plugged the value of c into the first equation i created. i then got 7A + 4(-A+100) = 592. after that, i distributed the 4 into the parentheses and got 7A - 4A + 400 = 592. from there, you solve and get 3A = 192. divide 3 from both sides, and get the value of A = 64. then, you go back to the second equation, A + C = 100, and plug in your value of A to get 64 + C = 100. you can then go on to solve for C and get 36. your final answer is 64 adult tickets and 36 children tickets were sold.

Scrat [10]

Answer:

1, 3, 4, and 10

Step-by-step explanation:

To get a y value, substitute the x value into the equation they gave you (y = 3x - 5). For the x value 2:

y = 3(2) - 5

y = 6 - 5

y = 1.

To get a missing x value, solve for x in the equation they gave you. You were given the y value, so you can substitute that into the equation.

(4) = 3x - 5

Add 5 to both sides

9 = 3x

Divide both sides by 3

3 = x

Do the same with 7

(7) = 3x - 5

Add 5

12 = 3x

Divide by 3

4 = x

For the last one, you're given x so substitute it into the equation:

y = 3(5) - 5

y = 15 - 5

y = 10

What function is the inverse of f(x)=2x+3

almond37 [142]

Answer:

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

Step-by-step explanation:

To find the inverse function, solve for y:

x = f(y)

x = 2y +3

x -3 = 2y

(x -3)/2 = y

The inverse function is ...

$\boxed{f^{-1}(x)=\dfrac{x-3}{2}}$
