(21×15)9= 315×9= 2,835. Hope this helps i used a calculator.
Answer:
Graph A
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Since we are dealing with a slope of zero, we replace m with 0:
y = 0x + b
y = b
Here, we see that we would have a horizontal line. Therefore, graph A would be our answer.
The answer is 32
The number of subsets is always 2^n where n is the number of elements in the set; in this case 5. There should be 2^5=32 subsets including the empty set and the set itself.
Answer:
![-2x-11z](https://tex.z-dn.net/?f=-2x-11z)
Step-by-step explanation:
You have to remember that,
![(-)*(-) = (+)\\(+)*(+)=(+)\\(-)*(+) = (-)](https://tex.z-dn.net/?f=%28-%29%2A%28-%29%20%3D%20%28%2B%29%5C%5C%28%2B%29%2A%28%2B%29%3D%28%2B%29%5C%5C%28-%29%2A%28%2B%29%20%3D%20%28-%29)
lets solve now
![-(7x+4z)-3x+(8x-7z)\\-7x-4z-3x+8x-7z\\-7x-3x+8x-4z-7z\\-10x+8x-11z\\-2x-11z](https://tex.z-dn.net/?f=-%287x%2B4z%29-3x%2B%288x-7z%29%5C%5C-7x-4z-3x%2B8x-7z%5C%5C-7x-3x%2B8x-4z-7z%5C%5C-10x%2B8x-11z%5C%5C-2x-11z)
hope this helps you
please let me know if you have any other questions :-)
Step-by-step explanation:
First, reflect over line k:
(2, 5) → (-5, -2)
Then, reflect over the x-axis:
(-5, -2) → (-5, 2)
