Answer:

y = -2/21(x)+5

Step-by-step explanation:

We know that the formula to find the slope of an a line y = mx + b where m is the slope and b is the y-intercept.

The formula of slope is m = (y2-y1)/(x2-x1)

Using the two points given, we can find the slope:

m = (7-5)/(-21-0)

m = -2/21

b = 5 because (0,5) is the y-intercept

y = -2/21(x)+5

jamal calculated that it costs $0.43 per mile and $4.00 per day to operate his car. if jamal drive m miles over d days , which e

DaniilM [7]

Answer:

c = 4(d) + .43(m)

Step-by-step explanation:

We can test this by plugging in numbers for each of the variables. Let's say Jamal drove 5 miles over 2 days.

c = 4(2) + .43(5)

c = 8 + 2.15

c = $10.15

Have a nice day!

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
