Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees none of the other lines add up to 180 degrees and are also part of a vertical pair

Write the equation of the line that passes through the points (1,9) and (-1,1). Put
SpyIntel [72]

Answer:

Point slope form

                 y - 9 = 4(x-1)

Equation of the straight line passing through the point (1,9) and slope 'm' = 4 is    4 x - y +5=0

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the points are (1,9) and (-1,1)

slope of the line

                m = \frac{y_{2}-y_{1}  }{x_{2} - x_{1} }

               m = \frac{1-9}{-1-1}

             m = 4

<u><em>step(ii):-</em></u>

Equation of the straight line passing through the point (1,9) and slope 'm' = 4

                     y-y₁ = m( x-x₁)

                   y - 9 = 4(x-1)

                  y -9 = 4x-4

           4 x - y -4+9 =0

          4 x - y +5=0

Equation of the straight line passing through the point (1,9) and slope 'm' = 4 is    4 x - y +5=0

If the area of a circle measures 16 pi cm2, what is the circumference of the circle in terms of pi
Fiesta28 [93]

Answer: 8 pi

Step-by-step explanation: So we know that area of a circle is pi times r^2 so if we reverse that formula it would be square root of 16 pi which would be 4 pi and divide by pi so the radius is 4. And we know that the formula for circumference is 2 times pi times r, so 2 times 4 times pi is 8 pi. 8 pi is the cIrcumference! :)

6. What impact does the 5 have in the following equation. y = 5(x+2)^2 +
yulyashka [42]

Answer:

B. It makes the graph really narrow.

Step-by-step explanation:

\displaystyle Y = A[X - H]^2 + K

In the Vertex Formula, any <em>fraction</em><em> </em>you store in for <em>A</em><em> </em>will result in a <u>vertical</u><u> </u><u>shrink</u>, widening the graph, whereas any <em>whole number</em> you store in for <em>A</em> will result in a <u>vertical stretch</u>, narrowing the graph.

I am joyous to assist you at any time.
