Answer:
Option 1, 2 and 4
Step-by-step explanation:
3x-4y-8= 12
3x-4y= 12+8 (bring constants to 1 side)
3x-4y= 20 (simplify)
For a point to be a solution of the above equation, substitute the x and y coordinates into 3x-4y and see if it equals to 20.
Option 1: (0, -5)
3(0)-4(-5)= 20
This is correct
2) (4, -2)
3(4)-4(-2)=20
This is correct
3) (8,2)
3(8)-4(2)= 16
This is incorrect.
4) (-16, -17)
3(-16)-4(-17)= 20
This is correct.
5) (-1, -8)
3(-1)-4(-8)= 29
This is incorrect.
6) (-40, -34)
3(-40)-4(-34)= 16
This is incorrect.
Answer:
20
Step-by-step explanation:
Given function f(x)=![\[x^{2}-x\]](https://tex.z-dn.net/?f=%5C%5Bx%5E%7B2%7D-x%5C%5D)
We need to find f(-4) which means we need to find the value of the function when x=-4
.
On substituting x=-4 in the given function:
f(-4)=![\[-4^{2}-(-4)\]](https://tex.z-dn.net/?f=%5C%5B-4%5E%7B2%7D-%28-4%29%5C%5D)
Square of -4 is 16.
Hence, f(-4)=![\[16+4\]](https://tex.z-dn.net/?f=%5C%5B16%2B4%5C%5D)
=
Hence the value of the given function f(x)=
when x=-4 is 20.
Well, if you are asking how much is for each avocado, then what I did is I divided 27 by 12 and I got 2.25
Answer:
6.71
Step-by-step explanation:
c=
