Change the quadratic equation y= x^2+4x-5 from standard form to vertex form. 1. Transpose the -value to the left side of the equation.

2. Complete the square of the expression on the right side of the equation to get a perfect square trinomial. Add the resulting term to both sides.

3. Add the numbers on the left and factor the trinomial on the right.

4. Transpose the number across to the right side to get the equation into the vertex form, .

5. Make sure the addition and subtraction signs are correct to give the proper vertex form.

a. y= (x---2)^2

b. Y+9=(x+2)^2

c. y= (x---2)^2---9

d. y= a (x-h)^2 + k
Y= [x - (-2)]^2+ (-9)

e. Y=(x+2)^2-9

f. Y+5 = x^2+4x

g. Y+5+_4_=x^2+4x+_4_

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
