Yes just plug in x and y so yes

y > 5 + 6*x

10 > 5 + 6*1 .... replace x with 1, replace y with 10

10 > 5 + 6

10 > 11 ... this is a false statement because 10 is smaller than 11

Since the last statement is false, this means the first inequality is false when (x,y) = (1,10)

The given point is <u>not</u> a solution

Erin was completing the square of the quadratic function in order to find the extreme value. What is the next step in the proces
Lady bird [3.3K]

Step-by-step explanation:

ax^2+bx+c=0

a=leading term

ok so if the leading term is positive then opens up and has a <u>min</u>

if leading term is negative then opens down and has a <u>max</u>

leading term is positive

1x^2+8x

it has a min

to complete the square, move c aside take 1/2 of b and square it

b=8

8/2=4

4^2=16

now add that to both sides

x^2+8x+16+6=0+16

factor perfect square

(x+4)^2+6=16

subtract 6

(x+4)^2=10

subtract 10

(x+4)^2-10=0

vertex aka min or max is (h,k) when ou have

y=a(x-h)+k

h=-4

k=-10
