Answer:
false
Step-by-step explanation:
X times X times X times X times X equals X^5 not 5X
Answer:
<em>The slope is:</em>
![m=-\frac{3}{2}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B3%7D%7B2%7D)
Step-by-step explanation:
The slope m of a line is calculated using the following formula
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Where the points
and
are two points belonging to the straight line
Notice in the graph that the line passes through the points
(0, 2) and (2, -1)
Then the slope is:
![m=\frac{-1-2}{2-0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1-2%7D%7B2-0%7D)
![m=\frac{-3}{2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-3%7D%7B2%7D)
I got 67 but I can guarantee it’s right
Answer:
No solution
Step-by-step explanation:
![-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9\\\\](https://tex.z-dn.net/?f=-3x-4y-3z%3D-7%5C%5C2x-6y%2B2z%3D3%5C%5C5x-2y%2B5z%3D9%5C%5C%5C%5C)
Lets consider the equation 2.
Here we multiply the LHS and RHS with (-1).
![-3x-4y-3z=-7\\-(2x-6y+2z)=-3\\5x-2y+5z=9\\\\](https://tex.z-dn.net/?f=-3x-4y-3z%3D-7%5C%5C-%282x-6y%2B2z%29%3D-3%5C%5C5x-2y%2B5z%3D9%5C%5C%5C%5C)
Hence,
![-3x-4y-3z=-7\\-2x+6y-2z=-3\\5x-2y+5z=9\\\\](https://tex.z-dn.net/?f=-3x-4y-3z%3D-7%5C%5C-2x%2B6y-2z%3D-3%5C%5C5x-2y%2B5z%3D9%5C%5C%5C%5C)
When we add the equations we get,
![0x+0y+0z=-10+9\\Hence,\\0=-1](https://tex.z-dn.net/?f=0x%2B0y%2B0z%3D-10%2B9%5C%5CHence%2C%5C%5C0%3D-1)
As 0 doesn't equal to -1, answer is d) No solution
