Answer:

Angle 1 = 80 (by definition)

Angle 3 = 180 - 80 = 100

Angle 4 + Angle 2 = 90

Also, Angle 2 = 40 (by definition)

So Anglee 4 = 50

The slope point equation of a line passing through the points (-3, -1) and (2, -6) is:
evablogger [386]

Answer:

y = -1x -4

Step-by-step explanation:

The point slope equation is y - y1 = m(x -x1).

You will have to plug in the points (-3, -1) and (2, -6).

y - (-1) = m (x - (-3))

To find "m", find y over x.

m = (y2 - y1) / ( x2 - x1)

m = (-6 + 1)/(2 + 3)

m = -5/5

m = -1

Then plug in "m"

y + 1 = -1(x + 3)

then distribute the "m" into the parenthesis and isolate y or subtract 1 from both sides.

y + 1 = -1x - 3

y = -1x -4

What are the solutions of the equation x4 + 6x2 + 5 = 0? Use u substitution to solve.
klio [65]

Answer:

x = i and x = i\sqrt{5}

Step-by-step explanation:

Given

x^{4} + 6x² + 5 = 0

Using the substitution u = x², then

u² + 6u + 5 = 0 ← in standard form

(u + 1)(u + 5) = 0 ← in factored form

Equate each factor to zero and solve for u

u + 1 = 0 ⇒ u = - 1

u + 5 = 0 ⇒ u = - 5

Convert solutions back into terms of x

x² = - 1 ⇒ x = \sqrt{-1} = i

x² = - 5 ⇒ x = \sqrt{-5} = i\sqrt{5}
