Answer:
m= rise/ run
Step-by-step explanation:
We can find the slope by
m= rise/ run
= change in y/ change in x
= ( y2-y1)/(x2-x1)
= vertical change/ horizontal change
I dont see anything maybe you forgot to add the answer'
-28+2r+3r+5
simplified it is -23+5r
Answer:
17 cows and 6 geese
Step-by-step explanation:
1. set up two equations:
C + G = 23 (number of cows and geese = total number of animals)
4C + 2G = 80 (cows have 4 legs, geese have 2 legs and the total # of legs is 80)
2. 2(C+G)=2(23) ===> 2C + 2G = 46
3. subtract 4C + 2G = 80 and 2C + 2G = 46 to equal 2C=34, divide by 2 and C=17 (17 cows)
4. apply 17 back to the original (C + G = 23) equation to get: 17 + G = 23, subtract 17 from 23 and G=6 (6 geese)
i hope the way i explained it was clear! :)
