Find the values of a and b such that x^2 + 3x + 4 = (x + a)^2 + b

URGENT!

*silly answers will be reported

a = 1.5

b = 1.75

Step-by-step explanation:

First, we need to solve and replace the result in the initial equation as:

Then, this equality apply only if the coefficient of is equal in both sides and the constant is equal in both sides.

It means that we have two equations:

So, using the first equation and solving for a, we get:

Finally, replacing the value of a in the second equation and solving for b, we get:

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
