False because 5 is associated with two values.
To be a function, the domain can only map to one range value, but in this case, 5 is mapped to two values, 1 and 3.
Answer:
A) -x + y = 2
B) x + 2y = 4
we add both equations
3 y = 6
y = 2
We put y = 2 into equation B)
x + 2 * 2 = 4
x = 0
***********************************************
A) -2x + y = 6
B) x + y = 0
We multiply B) by 2
B) 2 x + 2 y = 0 then we add A)
A) -2x + y = 6
3y = 6
y = 2
Therefore x = -2

Hello!
1.
The area of a rectangle is lenth * width
So 16 * 6 = 96
------------------------------------------------------------------------------------------------------
2.
The area of a square is a side^2
So 11^2 = 121
------------------------------------------------------------------------------------------------------
3.
The area of a parallelogram is base * height
So 14 * 9 = 126
------------------------------------------------------------------------------------------------------
4.
It is a parallelogram again
So 12 * 8 = 96
------------------------------------------------------------------------------------------------------
5.
The area of a triangle is
h is height and b is base
15 * 19 = 285
285/2 = 142.5
------------------------------------------------------------------------------------------------------
for number 6 I do not remember how to do that sorry
Hope this helps!<span />
Answer : The area of land a farmer own now is, 1790 acres
Step-by-step explanation :
Area of land a farmer owns = 1000 acres
Total area of land farmer buy = 120 acres + 160 acres + 700 acres
Total area of land farmer buy = 980 acres
Area of land a farmer sells = 190 acres
Thus, the remaining area of land a farmer has = Total area of land farmer buy - Area of land a farmer sells
The remaining area of land a farmer has = 980 acres - 190 acres
The remaining area of land a farmer has = 790 acres
Now we have to determine the area of land a farmer own now.
Area of land a farmer own now = 1000 acres + 790 acres
Area of land a farmer own now = 1790 acres
Therefore, the area of land a farmer own now is, 1790 acres
There's no equation for that
