Answer:
y = -1/2x + (-1)
Step-by-step explanation:
A ) equation would be X = Z / Y
B ) if X = 9 ------------> Y = 1/7
X = 21 ----------> Y = ?
21*1/7 = 21/7 , 21/7÷9 = 21*9/7 = 27
so Y equal 27
Answer: 254.714285714 or rounded to 255
Step-by-step explanation:
Have a good day:)
Is to long to explain so I'm doing quite
find the triangle side so 2.1 square minus 1.4 square it is equal to 2.45
now you just multiple 2.45 by 2 because if you notice 2.45 is the triangle side that is missing and this is only the half so multiple by 2 for get the X value, I hope this helps you.
Answer:
Below
Step-by-step explanation:
● 2 ( x-1) - 5 (x+9)
● 2x - 1 - 5x - 45
● 2x -5x -1 - 45
● - 3x - 46
● 5x - 5 - 7x + 14
● 5x - 7x - 5 + 14
● -2x + 9
