Answer:

(- 6, 10 ) and (- 1, 5 )

Step-by-step explanation:

Given the 2 equations

y = x² + 6x + 10 → (1)

y = - x + 4 → (2)

Substitute y =  x² + 6x + 10 into (2)

x² + 6x + 10 = - x + 4 ( subtract - x + 4 from both sides )

x² + 7x + 6 = 0 ← in standard form

(x + 1)(x + 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 6 = 0 ⇒ x = - 6

Equate these values into (2) for corresponding values of y

x = - 1 : y = - (- 1) + 4 = 1 + 4 = 5 ⇒ (- 1, 5 )

x = - 6 : y = - (- 6) + 4 = 6 + 4 = 10 ⇒ (- 6, 10 )

Which of the following categories of numbers describes √12 ?
Natali5045456 [20]

Answer:

√12 = irrational number

Step-by-step explanation:

Irrational numbers are decimals that are non-terminating (don't stop) and non-repeating (don't have a pattern).  Non-perfect squares, or square roots that do not have a factor that is multiplied by itself, when solved it will produce a non-terminating, non-repeating decimal:

(Does anyone understand this???)
professor190 [17]

Answer:

y=-4x-8

Step-by-step explanation:

use points (0,-8) and (-2,0) and plug into slope formula.

slope formula=(y2-y1)/(x2-x1)

(0-(-8))/(-2-0)=-4

you get y=4x+b

use point (-2,0) to find b

you get y=-4x-8
