Answer: $3.50

Explanation: First, you want to do 70(1.05) and get 73.5. The way you get 1.05 is by adding 0.05 (5%) to 1 and get 1.05. Next, you want to do 73.5-70. The reason you should do this is because the number 73.5 is including both the selling price and the sales tax, and the question is asking for just the sales tax. Finally, 73.5-70 is 3.5, AKA your final answer, $3.50. I hope this helped!

Answer:

Sales tax: 3.5$

Total Price: 73.5$

Step-by-step explanation:

the percentage of tax is that much of the total price. if there is 50% sales tax (unrealistic) and the item costs 100 dollars without any tax, then the tax would be 50 dollars. To find this, turn the percent into a decimal (move the decimal place to the left twice) and multiply that by the price. To do this with this problem, use this strategy. 70 times .05= 3.5. Therefore the tax is 3.5$. hope this helps!!

Pentagon PQRST is drawn on a coordinate plane below. what rule best represents a dilation to create pentagon PQRST with a scale factor of 1/2 and with the origin as the center of dilation?

Answers

Answer: [tex](x,y) \to (\dfrac12 x, \dfrac12 y)[/tex]

Step-by-step explanation:

Dilation is a transformation, in which the size of the image gets changed but not shape.

The rule of dilation with scale factor k and wither origin as center of dilation :

(x,y) → (kx, ky)

Here , [tex]k= \dfrac12[/tex] , center of dilation = Origin

Then, the rule best represents a dilation to create pentagon PQRST will be :

[tex](x,y) \to (\dfrac12 x, \dfrac12 y)[/tex]

Given the two points (3, -1) and (5,3), explain how to write the equation of the line in slope intercept form.


*Calculate Slope first

*Calculate y-intercept second

*Write your answer in the form y=mx+b (HINT: you will need to find m and b)


Help quickly!!! I will give brainylist or whatever

Answers

Can you add an image please?

1. To find slope use the slope equation which would be (3 - -1)/ (5-3). The slope is m = 4\2 which is m = 2

2. Plug in one of the points to find the y-intercept. Using the point (5,3) , you would plug this point into the slope intercept equation, along with the slope which was found. 3= (2 x 5) +b. Solving this equation b=-7

3. The slop intercept form is y = 2x - 7


I hope this is the right answer!

What is the final price of an item that cost $14 with a 75% discount

Answers

Sale Price = $3.5 (answer). This means the cost of the item to you is $3.5. You will pay $3.5 for a item with original price of $14 when discounted 75%. In this example, if you buy an item at $14 with 75% discount, you will pay 14 - 10.5 = 3.5 dollars.
$3.50 because 14 - 75% or you should do convert 75% to a decimal .75 so u should do

A line passes through the point (2,-6) and has an initial value of 6. What is the rate of change for this line?
A. -12
B. -6
C. -1/6
D. 6

Answers

-6
Just did the question

-6

We assume "initial value" means the y-intercept is (0, 6). The rate of change is the "rise" divided by the "run" between the two points.

rise = -6 -6 = -12 . . . . difference of y-values

run = 2 -0 = 2 . . . . . . difference of corresponding x-values

rate of change = rise/run = -12/2 = -6

The rate of change of this line is -6.
