On a grid if you have paddy paper use it, you draw the shape with the coordinates given to you then you rotate it 180°.

So basically if the coordinates were (5,7) after the 180° rotation from the origin, it would be (-5,-7)

Because the rule for a 180 degree rotation is (-x, -y).

180° btw is when yo paper is completely upside down from how it was before

Answer:

f(x) = x^2 - 3x + 1.

Step-by-step explanation:

If the roots of this polynomial are 1 and 2, the corresponding factors are (x - 1) and (x - 2).  Multiplying, we get

f(x) = (x - 1)(x - 2) = x^2 - 3x + 1

The polynomial of least degree with roots 1 and 2 is f(x) = x^2 - 3x + 1.

Jon bought a printer for $189 and a set of printer cartridges for $192. Sales tax on these items was 6.5%. What is Jon's total b
julia-pushkina [17]
So first we need to find the total before tax. Let's add up the two prices:

189+192=381

So we know that the total before tax is $381. Now we are told that the sales tax on these items is 6.5%. It would be easier for us to convert 6.5% to a decimal in order to multiply. Let's convert 6.5% to a decimal by dividing by 100:

\frac{6.5}{100}=0.065

Now that we have the sales tax in decimal form, let's multiply this sales tax by the total amount of the items before tax ($381):

381*0.065=24.77

This means that $24.77 is the tax for this purchase. To find the total amount that Jon paid for these items after tax, you must add the tax to the total amount before tax to give you:

381+24.77=405.77

So now we know that Jon's total bill for these items is $405.77.

hammer [34]

Answer:

<u>Answer</u><u>:</u><u> </u><u>3</u><u>5</u><u>/</u><u>1</u><u>8</u>

Step-by-step explanation:

\frac{ \{ \frac{3}{4} -  \frac{5}{2}  \} }{ \{ \frac{3}{5}  -  \frac{3}{2}  \}}   =  \frac{( -  \frac{7}{4} )}{ (-  \frac{9}{10} )}  \\  \\   =  \frac{7}{4}  \div  \frac{9}{10}

use the reciprocal of 9/10 :

=  \frac{7}{4}  \times  \frac{10}{9}  \\  \\  =  \frac{35}{18}
