Thomas has $30 to spend at the amusement park. Rides cost $2 each and admission at the gate is $6. What is the maximum number of rides that Thomas can go on?
A.2r + 6 < 30

B.2r + 6 = 30

C.6r + 2 = 30

D. 6r + 2 > 30

Answers

Answer:

B.2r+6=30

Explanation:

It costs $6 dollars just to get in. Subtract 6 from 30. 30-6=24

Divide 24 by 2. 24 divided by 2 equals 12.

Let the number of rides = r

Multiply the price per ride by number of rudest over 2r, you then add the admission to that to get 2R + 6

He has $30 so the total he can spend has to be less than or equal to $30

2r + 6 <= 30

Answer:

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis. the y-axis is the point (-x,y).

Please help me figure out the answer to this I'm a bit confused

Answers

Answer:

y= 1/2x + 1

Step-by-step explanation:

Refer to y=mx+b, m=slope and b= y-intercept

First, you find the slope: you can find the slope by finding the rise over run between two points. Rise= 1, Run=2. The slope is rise/run (rise over run), so the slope would be 1/2 (one half).

Next, find the y-intercept. It is where the line touches the y-axis. Here, it would be 1.

Finally, put these in y=mx+b form:

y=(slope)x+(y-intercept) ---> y= 1/2x + 1

I tried my best to explain everything, I hope you found this helpful!

The answer is. y = 1/2x + 1

Rewrite the equation 2x + 6y = 7 in slope-intercept form.

y = -(2/3)x + 1 1/3
6y= -2x +7
y = -2x + 1 1/6
y = -(1/3)x + 1 1/6

Answers

Answer: y = -2x + 1 1/6

Steps:
2x + 6y = 7
2x + y = 7/6
y = 7/6
y = -2x + 7/6
y = -2x + 1 1/6

I Got y = -2x + 1 1/6 :D
