Answer:
B. Commutative Property of Multiplication
Step-by-step explanation:
Commutative Property of Multiplication means that you swap the numbers and get the same answer like 2 x 3 =6 or 3 x 2 =6
Answer: (50,-20)
Step-by-step explanation:
Point B is (100,0).
Point A is (0,-40).
To find C you need the midpoint of both A and B, which means you add both coordinate x and coordinate y together to find the middle of both.
Midpoint of x coordinates:
100+0= 100
100÷2= 50
Midpoint of y coordinates:
0+(-40)= -40
-40÷2= -20
Therefore, point C is (50,-20)
Let's write the parametric line
(x,y,z) = (0,2,8) + t(5,-1,4)
(5,-1,4) is called the direction vector of the line. It's normal to the plane
5x - y + 4z = constant
We get the constant by substituting the point (3,0,7),
5x - y +4z = 5(3) - 0 + 4(7) = 43
5x - y +4z = 43
Answer: Pigs = 21
Chicken = 45
Step-by-step explanation:
Let the pigs be represented by p
Let the chicken be represented by c.
From the question,
p + c = 66
4p + 2c = 174
4 × ( p + c = 66)
1 × (4p + 2c = 174)
4p + 4c = 264
- 4p + 2c = 174
2c = 90
c = 90/2 = 45
There are 45 chickens
Simce the farmer has a total of 66 animals, the number of pigs will be:
= 66 - 45
= 21 pigs
