5 / 16

m = rise/run = y2 - y1 / x2 - x1

m = 2-7 / (-4) - 12 = -5 / -16

m = 5 / 16

Can anyone please help me with number 17?
sweet-ann [11.9K]

The answer is G. I know because, 1.75 * 3 (slices of pizza) = 5.25.

13.75 - 5.25 = 8.5

8.5 / 4 (hot dogs) = 2.1 (price per hot dog)

We can apply this to Sarah by saying

2 * 1.75 = 3.5

3 * 2.1 = 6.3

Added equals 9.8 or 9.75 (Sarah's total)

Correct me if I am wrong hope this helps:)

Suppose a designer has a palette of 8 colors to work with, and wants to design a flag with 2 vertical stripes, all different col
Vesna [10]

Answer:

For a flag with 2 different colours, there are 8 possible colours for the first colour to be chosen from and 7 possible colours (excluding the first colour already chosen) for the second colour to be chosen from, given that colours are different. Hence there are a total of 8 x 7 = 56 possible flags to be created.

Solve the system using elimination.
KIM [24]
We can't eliminate as is so we have to change something up there in the equations to get either the x values the same number but opposite signs, or the y values the same number but opposite signs.  I chose to change the y values to the same number but different signs. In the first equation y is -3y and in the second one, y is -8y. The LCM of both of those numbers is 24, so we will multiply the first equation by an 8 (8*3=24) and the second equation by 3 (3*8=24) but since they are both negative right now, one of those multiplications has to involve a negative because - * - = +. Set it up like this:
8(-10x - 3y = -18)
-3(-7x - 8y = 11)
Multiply both of those all the way through to get new equations:
-80x - 24y = -144
 21x  +24y = -33
Now the y's cancel each other out leaving only the x's:
-59x = -177 and x = 3.  Now plug that 3 into either one of the original equations to find the y value.  Either equation will work; you'll get the same answer using either one. Promise. -7(3) - 8y = 11 gives a y value of -4.  so your solution is (3, -4) or B above.
