Find the slope of the line graphed below
igomit [66]

We are given two points: (-1, -1) and (1, -4). Slope is calculated as the change in y over the change in x, or rise over run.

The change in y is the difference of the two y coordinates (it doesn't matter the order): -1 - (-4) = 3

The change in x is the difference of the two x coordinates (this order depends on the order that you subtracted the y coordinates; they must be the same order): -1 - 1 = -2.

So, the slope is 3/-2

You have 12 coins, one of which is fake. The fake coin is indistinguishable from the rest except that it is heavier. Can you det
Anton [14]
Yep! 
Weighing #1: Start off by splitting the pile of 12 coins evenly into two piles, 6 in each pile. Put one pile on each side of the balance. The side that is weighed down has the fake coin it in. Ignore the other 6 coins.

Weighing #2: Now you have 6 coins left. Split the pile evenly again, 3 in each pile. Repeat the same process and put each pile on one side of the balance. The side that is weighed down has your fake coin in it. Ignore the other 3 coins.

Weighing #3: You have 3 coins left. Take two coins, whichever two you like, and weigh them. If they weigh the same, then the one you didn't weigh is the fake one. If one is heavier, then that heavier one is your fake coin.

Please help me guys it is due today there is a second part i will do anything so ANSWER PLS!!! ASAP
Fantom [35]

Answer:

see below

Step-by-step explanation:

To find the combined length of Pine and Elm and the lengths together

Pine +Elm

We are estimating by rounding to the nearest whole number

Pine is 2.7 so it rounds to 3 because we look at the .7 and since .7 is greater than .5 it rounds the 2 to 3

Elm is 8.9  so it rounds to 9 because we look at the .9 and since .9 is greater than .5 it rounds the 8 to 9

2.7 + 8.9 rounds to 3+9 = 12

12 is reasonable because the actual answer is 2.7+8.9 = 11.6 which rounds to 12
