Is the relationship shown by the data linear? If so, model the data with an equation. x= -7, -5, -3 ,-1 , y = 5, 9, 13, 17
PIT_PIT [208]
First we take the two points (-7,5) and (-5,9).
Compute the slope: \frac{9-5}{-5+7}=2
Then the linear relation may be in the following form y=2x+b
Since the point (-7,5) is on the line, then 5=-7(2)+b\text{ then }b=19.
The relation is then y=2x+19.
We check that the other point are on the above line:
2(-3)+19=13 \text{ OK}\\2(-1)+19=17  \text{ OK}
We have then a linear relation.

PLEASE ANSWER CORRECTLY Which of the following is an equivalent for of 5x2 - 13 x-6 ?​
Pepsi [2]

Answer: None of these answers are correct; tell this to your teacher. The 1st answer is closest to correct.

Step-by-step explanation:

The second and fourth answers are not viable because expanding them would result in x^3 which is not in the original equation.

1. 5x(x+3)-2(x+3)

5x^2+13x-6, This answer is closest to correct and may be correct in the case of a typo.

3. 5x(x-3)-2(x-3) ; Expand

5x^2-15x - 2x +6

5x^2-17x+6

the sales tax in your city is 4.4%.and an item costs $3 before tax. how much tax would you pay on that item
MrMuchimi
<h2>Greetings</h2>

Answer:

The tax is $0.12

Step-by-step explanation:

If you can imagine that price of $3 to be 100% of the price, you can simply add 4.4 onto this to find the percentage you need to find of the price:

100 + 4.4 = 104.4

So now you can use the percentage formula:

Amount x \frac{percentage}{100}

Simply plug all the values into this:

3 x \frac{104.4}{100}

3 x 1.04 = 3.12

Now you have the total price and you can simply minus the item cost without tax:

3.12 - 3 = 0.12

<h3>So the tax is $0.12!</h3><h3 /><h2>Hope this helps!</h2>
