Answer 1

Answer:

Answer:

i think C

Step-by-step explanation:

$(1)/(2)$

Solution,

Letthepointsbe AandB

A(-4,1)------>(X1,y1)

B(2,4)---------->(x2,y2)

Now,

Gradient:

$(y2 - y1)/(x2 - x1)$

$(4 - 1)/(2 - ( - 4))$

$(3)/(2 + 4)$

$(3)/(6)$

$(1)/(2)$

Goodluck on your assignment...

Step-by-step explanation:

The price of a t-shirt was reduced from $18.00 to $13.00. Find the percent of the discount.

Answers

1st find discount
18-13=5
5 is discount

discount from original
5/18=x%
percent means parts out of 100 so x%=x/100
5/18=x/100
multiply both sides by 900
250x=9
divide both sides by 250
x=27.77777
aprox 28%

answer is 28%

How would I use the distributive property to rewrite (9-p)3 and then simplify?

Answers

1.To make it easier, you can rewrite the 3 to the other side!
3(9-p)
2.To distribute, you just take the term on the outside of the parentheses and multiply it with each term on the outside (seperately)
3 * 9 = 27
3 * -p = -3p
3. This would leave you with the following equation...rewrite it with the letters first.
-3p + 27 or 3p - 27
either way works!

do 9 times 3 and -p times 3. when you simplify you should get 27-3p

A pencil at a stationery store costs $1, and a pen costs $1.50. Shawn spent $12 at the store. He bought a total of 9 items. Which system of equations can be used to find the number of pencils (x) and pens (y) he bought?

Answers

x= 3 pencils 3+6=9 items
y= 6 pens
So, Shawn bought 3 pencils and 6 pens. 1 pen equals 1.50 and a pencil only costs a dollar and he spent 12 dollars so now if he bought 6 pens and 3 pencils that would equal 12.

9x=£9. 9y=13.50. It has to be an even number of y or you will get a decimal and 12 is not a decimal. 7x+2y=£10 5x+4y=£11. 3x+6y=£12 The answer is three pencils and 6 pens.

Recall that the length a spring streches varies directly with the amount of weight attached to it. a certain spring stretches 5cm when a 10-gram weight is attached write a direct variation equation relating the weight x and the amount of stretch y.

Answers

Direct variation is y=kx

In this case, y=1/2x. The spring stretches 5 cm for every 10 grams. Therefore if y=5 and x=10, k would have to be 1/2. That's how we come up with our direct variation model.

$This\ spring\ stretches\ in\ proportion\ to\ weight,\ that\ is,\ for\ every \n 10\ grams\ of\ weight\ the\ amount\ of\ stretch\ is\ 5\ cm.\n \nx\ [g]\ \ \ |\ \ 10\ \ |\ \ 20\ \ |\ \ 30\ \ |\ \ 40\ \ |...|\ \ \ a\ \ \ |\n------------------\ny\ [cm]\ |\ \ 5\ \ \ |\ \ 10\ \ |\ \ 15\ \ |\ \ 20\ \ |...|\ \ (1)/(2) a\ \ |\n\na\ variation\ equation\ is\ y= (1)/(2) x$
