Step-by-step explanation:

$y = \sqrt{x + 7} - 1$

Replace x and y.

$x = \sqrt{y + 7} - 1$

Solve for y.

$x + 1 = \sqrt{y + 7}$

Square both sides.

$(x + 1) {}^{2} = y + 7$

$(x + 1) {}^{2} - 7 = y$

This is the inverse function or you can also say

${x}^{2} + 2x - 6 = y$

Answer:

11. 10, 20,30,40,50,60,70

12. 35, 45,55,65,75,85,95

Step-by-step explanation:

10 dollars per week for 7 weeks in equivalent to 10x7 which equals $70.

If you already had $25 you would do 10x7+25. Using PEMDAS you would multiply first (10x7=70) then add 25 (70+25=95)

Oksanka [162]

Answer: The cost of child's ticket = $10

The cost of adult ticket = $ 13

Step-by-step explanation:

Let x be the cost of a child ticket and y be the cost of an adult ticket.

Then According to the question, we have

$6x+2y=86..........................(1)\\\\10x+3y=139.......................(2)$

Multiply equation (1) by 3 and equation (2) by 2, then we have

$18x+6y=258.......................(1)\\\\20x+6y=278...........................(2)$

Subtract equation (1) from equation (2), we have

$2x=20\\\\\Rightarrow\ x=10$

Substitute the value of x in equation (1), we get

$60+2y=86\\\\\Rightarrow\ 2y=26\\\\\Rightarrow\ y=13$

Hence, the cost of child's ticket = $10

The cost of adult ticket = $ 13
