The answer would be x^2-18x+81. This can be found be writing "(x-9)^2" twice, and distributing. Combine like terms, and you should get this answer.
She was correct to multiply .75 by .15 to get .1125, but she forgot to add that value to .75 to get the total amount of fabric needed.
Answer:
(3, 1 ) is a solution
Step-by-step explanation:
To determine if the given points are solutions, substitute the x and y values into the left side of the equation and if equal to the right side then they are solutions.
(3, 1 )
3 + 4(1) = 3 + 4 = 7 = right side , then a solution
(2, 1 )
2 + 4(1) = 2 + 4 = 6 ≠ 7 ← not a solution
3.25 is the answer
Step-by-step explanation:
you would add them as decimals
Given is -
The variables y and x have a proportional relationship, and y = 5 when x = 4.
As we have to find the value of x when y= 8 so putting y = 8 in the above relationship, we get :
Hence, the answer is 6.4
