A farm has chickens and cows. You ask the farmer how many chickens he has, and how many cows he has. The farmer tells you he has 28 healthy animals, and they have a total of 64 legs. How many of his animals are cows.

Answers

Answer 1

Answer: Well, we know that cows have four legs, and chickens have two. See how many times two goes onto 64, and how many times four goes into 64. 64 divided by two is 32. There are 32 chickens. 64 divided by four is 16. There are 16 cows.

Find point-slope.(3/2, -1/2)
(-2/3, 1/3)

x1: 3/2
x2: -2/3
y1: -1/2
y2: 1/3

to find slope:
m= y2-y1/x2-x1

point-slope:
y-y1=m(x-x1)

Answers

this iis easie guise, why don't you do it? so
point slope=y-y1=m(x-x1)

so just subsitute
first find m
m=(y2-y1)/(x2-x1)=(1/3-(-1/2))/(-2/3-3/2)=(1/3+1/2)/(-2/3-3/2)=(5/6)/(-13/6)=-5/13
m=-5/13
subsitute
y-y1=-5/13(x-x1)
subsitute
y-(-1/2)=-5/13(x-3/2)
y+1/2=-5/13x+15/26
subtract 1/2 from both sides
y=-5/13x+15/26-13/26 (1/2=13/26)
y=-5/13x+2/26
y=-5/13x+1/13

Answer:

Step-by-step explanation:

Sample Answer:When a linear function is expressed in different forms, its slope and y-intercept remain the same. The slope from the equation is -1, and the y-intercept from the equation is 3. The slope from the table is -1, and the y-intercept from the table is −3. These are not the same functions.

Select the following numbers that cannot represent the area of a polygon.a. 68
b. 40
c. -5
d. square root 30
e. 0
f. -200

Answers

c. -5
e. 0
f. -200

Area cannot equal zero or a negative number

Answer: The answer is (c) - 5, (e) 0 and (f) - 200.

Step-by-step explanation: We are to select the correct numbers from the given options that cannot represent the area of a polygon.

We know that the area of any figure cannot be a negative number or zero.

So, the numbers which cannot represent the area of a polygon are - 5, 0 and - 200.

Thus, (c), (e) and (f) are the correct options.
