When eating out, it is customary to tip your server at least 15% of the cost of your meal. The graph shows a 15% tip, t, for a m

eal that costs m dollars.
Each of the following sets of numbers represents dollars. Assuming the graph is correct, which set of numbers is most appropriate to label the seven tick marks along the vertical axis (15% tip)?

Question 5 options:

15, 30, 45, 60, 75, 90, 105


1.50, 3, 4.50, 6, 7.50, 9, 10.50


5, 10, 15, 20, 25, 30, 35


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

Answer:

1.50, 3, 4.50, 6, 7.50, 9, 10.50

Step-by-step explanation:

The x axis represents the amount of money the meal (without tip) costs.

The question is asking what numbers should label the tick marks on the y-axis given that we are assuming a 15% tip.

So the question is really easy to solve. We see our first point is at (1,1) on the coordinate plane which has the meal costing $10. All you have to do to find the tip is to multiply $10 x (0.15%) = 1.50...

So 1.50 should label the first tick mark on the y-axis. You can do the same for all of the numbers. But only one answer choice gives 1.50 as an option, so answer choice 'C' is correct!

Hope this helps, let me know if you need further or better explanations!

Find the inverse of the following function.
Naddik [55]

For this case we must find the inverse of the following function:

f (x) = 8 \sqrt {x}

For this, we follow the steps below:

We change f (x) to y:

y = 8 \sqrt {x}

We exchange the variables:

x = 8 \sqrt {y}

We solve for y:

8 \sqrt {y} = x

We divide between 8 on both sides of the equation:

\sqrt {y} = \frac {x} {8}

We raise both sides of the equation to the square to remove the root:

y = (\frac {x} {8}) ^ 2\\y = \frac {x ^ 2} {64}

So, the inverse is:f ^ {- 1} (x) = \frac {x ^ 2} {64}

the larger triangle is a dilation of the smaller triangle with a center of dilation at (2,-1). Whatbis the scale factor of the d
leva [86]
I think it’s 2. You can see this because if you count the squares in the smaller triangle it is 3 along. You would then need to double the amount of squares on all sides. This makes the larger triangle now 6 squares along. 6/3 is 2 making the scale factor 2. (This is only if I have read the question correctly and we are calculating small to big. If I have read it wrong and it is big to small it would be 1/2)

The sum of 8 and B is greater than 22
Alinara [238K]

Given:

The sum of 8 and B is greater than 22.

To find:

The inequality for the given statement and its solution.

Solution:

We know that, sum of two number is the addition of two numbers.

Sum of 8 and B = 8+B

It is given that, the sum of 8 and B is greater than 22.

8+B>22

Subtracting 8 from both sides, we get

8+B-8>22-8

B>14

Therefore, the required inequality for the given statement is 8+B>22 and the solution is B>14.
