Answer:

y = 4

Step-by-step explanation:

equate these two equations, obtaining 2x+2 = x^2+3.  Solving this for x, we get:

x^2 - 2x - 2 + 3 = 0, or x^2 - 2x + 1 = 0.  This is equivalent to (x - 1)^2 = 0.  There's a double root here:  x = 1 and x = 1.

Since Y=2x+2, y = 2(1) + 2, or y = 4, when x = 1.

The y-coordinate of the solution is y = 4.

Manuel bought 9 pounds of apples. He has eaten three fourths
Diano4ka-milaya [45]

1. So, since Manuel bought 9 pounds and ate 3/4 of 1 pound, he has 8.25 pounds left  (9  - 0.75  = 8.25)

2. Let us call "x" the cost of 1 pound of apples

3. (8.25) * (x) = $15


4. x = $1.81818  rounded to the nearest dollar is $2 / pound

Change the equation of the parent square root function to represent the equation of the graphed function. Enter the correct answ
Dennis_Churaev [7]

The equation of the parent square root function to represent the equation of the graphed function will be, y=√x-2

According to the statement

we have to show the square root function as a equation in the graphical representation.

So,

we know that the definition of a

Graph a diagram showing the relation between variable quantities, typically of two variables and it also show the relation between more than two variables.

Now, we know that the definition of Equation is a mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

And the equation obtained from the graph is a y=√x-2 by a some calculations in the graph.

So, The equation of the parent square root function to represent the equation of the graphed function will be, y=√x-2
