Answer:

y = 2x+1

Step-by-step explanation:

$2y =4x+8\\\\ Write \:in \: y =mx+b \:form\\\\\frac{2y}{2} = \frac{4x}{2} +\frac{8}{2} \\\\y =2x +4\\m =2\\(1,3) =(x_1,y_1)\\Substitute\:values\:into\:point-slope\:form\\\\y-y_1=m(x-x_1)\\y-3=2(x-1)\\y-3 = 2x-2\\y=2x-2+3\\y =2x+1$

If you rolled two dice what is the probability that you would roll a 4 or a 5

Masja [62]

Hello there! Given that normal dice are numbered 1-6, individually rolling a 4 or a 5 would give a 1/6 probability. That converts to about 17% as a percentage because we can multiply 1 by 100 to get 100/6, then divide 100 by 6 to get 16.6666. When rounding, that gives approximately 17%. However, if we combined probabilities, we would find that rolling a 4 or a 5 collectively gives a 2/6 probability, which is approximately 33% as a decimal.

In terms of individual probabilities, you would be 17% likely to roll one of them. In terms of collectiveness, the likelihood of rolling a 4 or 5 would render 33% on each die. If you need additional help, let me know and I will gladly assist you.

The Cooper family, consisting of 6 children and 2 adults, goes to the movies and pays a total of $86. The Griffen birthday party

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
