To solve a system of inequalities ayana isolated y in the first equation and then substituted for y in the second equation. what

vitfil [10]

Answer:

(- 3, - 6 ) , (1, 2 )

Step-by-step explanation:

2y = 4x ( divide both sides by 2 )

y = 2x → (1)

x² + y = 3 → (2)

Substitute y = 2x into (2)

x² + 2x = 3 ( subtract 3 from both sides )

x² + 2x - 3 = 0 ← in standard form

(x + 3)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1

Substitute theses values into (2) for corresponding values of y

x = - 3 : y = 2(- 3) = - 6 ⇒ (- 3, - 6 )

x = 1 : y = 2(1) = 2 ⇒ (1, 2 )

Points N and R both lie on circle O. Line segment RQ is tangent to the circle at point R.

ANEK [815]

Answer:

Perimeter ΔRON = 18.66 units

Step-by-step explanation:

Complete Question has these information given as well:

Circle with center O
RN = QN
RQ = $5\sqrt{3}$
ON = 5 units
RQ is tangent

Now, we draw an image according to the information given. THe image drawn is attached.

Looking at the figure, we can say the perimeter of triangle RON would be:

RON = OR + ON + RN

We know according to tangent theorem, QN = QR

RN is equal to that as well and RN = $5\sqrt{3}$

Now,

OR and ON is the radius, which is "5"

Perimeter of RON = 5 + 5 + $5\sqrt{3}$ = 10 + $5\sqrt{3}$ = 18.66 units

Perimeter ΔRON = 18.66 units

1st slope is -1/3. 2nd slope is 6

slope is same in parallel lines so not parallel

slopes are negative reciprocals in perpendicular lines so they aren't perpendicular

they are called oblique
