Answer:
Step-by-step explanation:
y = (x^2 + 4x) + 2
Take 1/2 of the linear term 4/2 = 2 and square that result. 2^2 = 4.
Put it after 4x
y = (x^2 + 4x + 4) +2 Subtract what you put inside the brackets on the outside.
y = (x^2 + 4x + 4) + 2 - 4 Combine the right.
y = (x^2 + 4x + 4) - 2 Express the brackets as a square.
y = (x + 2)^2 - 2
That's your answer
a = 1
h = 2
k = -2

Answer:
The difference between the number of pounds of strawberries and the number of pounds of grapes in the mix is 33.42 pounds.
Step-by-step explanation:
I think that the right question is:
In the system of equations shown, x represents the number of pounds of strawberries, and y represents the number of pounds of grapes in a fruit mix. x y = 15.82 and x - 1.90y = 72.5. what is the difference between the number of pounds of strawberries and the number of pounds of grapes in the mix
Given that:
x represents the number of pounds of strawberries, and y represents the number of pounds of grapes in a fruit mix.
The equation relating x and y is given by the equation:
Subtracting equation 2 from equation 1, we get:
Putting y = 19.54 in equation 1 to get:
Therefore, the difference between the number of pounds of strawberries and the number of pounds of grapes in the mix is given by:
The difference between the number of pounds of strawberries and the number of pounds of grapes in the mix is 33.42 pounds.
