Answer:

1.07p

Step-by-step explanation:

The tax  equals the price times the tax rate

We know the price p and the tax rate 7%

tax = p*7%

Changing this to decimal form

tax = .07p

The  final price of the item is the sales tax plus the price

final price = tax + price

                   .07p +p

                  1.07p

If you have an item that costs 10 dollars and a sales tax of 7% you could do it this way


10 * 7/100 = 0.70 dollars.


The total cost is 10.70 dollars. or 10 dollars and 70 cents.

The best way to do the total however is to multiply the cost by 1.07. You will get the number the customer has to pay.

10 * 1.07 = 10.70

So for any price (p) it would be 1.07*p

Step-by-step explanation:

Hello!
I'd love to help you learn.
I see the formula attached is 4*(\frac{1}{2})^{x} =-2^{x}-1\\

This problem is explaining you to graph, since algebraically it's a little more harder to try and find the solution.

Since they're both equal to each other, we can assign a variable like y, so we can make them into two individual lines.

You can use your scientific calculator to graph lines like this, or otherwise there are online sources (Desmos helps alot!) which can graph two equations as so.

Now that we have the corresponding system of equations, we can graph both.

y=4*(\frac{1}{2})^x\\ y=-2^x-1
Let's graph them on Desmos on the same plane. The answers are attached. Red is the first equation, blue is the second.

What determines the solutions of a system of equations?

-No solution: the two lines will never intersect/does not intersect ever, which means that there are no set point where it satisfies both equations.

-One solution: the two lines intersect once and only once, meaning that there is that one set point where the x and y values both satisfy both equations.

-Multiple solutions: the two lines will intersect each other multiple times, meaning there are multiple set points where the x and y values satisfy both equations. You usually will not have to worry about these problem sets.

-Infinite solutions: the two lines are both the same line, which means every x and y value will satisfy both equations.

Looking at the solution attached, we can see that there are no places where a system of equations intersect, therefore ruling it that they have no solution.

And to answer your last question, an asymptote is a imaginary line in which a equation can approach closely and closely, but will never touch that imaginary line. Think of a line at y=\frac{1}{x}. When you graph it, you can see that the two lines never ever EVER intersect the y-axis, or x=0; giving that x=0 as a vertical asymptote.

What is the experimental probability that both coins land on the same side on Isidro’s next toss
Musya8 [376]

Answer:

1/2, or 0.5

Step-by-step explanation:

There are 4 ways that 2 coins can fall...

Both heads (this satisfies our situation)

1st coin heads, 2nd coin tails

1st coin tails, 2nd coin heads

Both tails (this satisfies our situation)

We have 2 out of 4 ways to satisfy this situation, so our experimental probability is

P = 2/4 which reduces to

 P = 1/2 , or 0.5 as a decimal

PLEASE HELP I'LL MARK YOU BRAINLIEST IF YOU'RE CORRECT I don't understand this​
mario62 [17]
The y-intercept of the function is at y = -3 so the options that don’t include it are off the table. The only possible answer is option C. Option A doesn’t work because plugging in positive values would give negative numbers within the square root which isn’t defined in the real numbers.
