If you're talking about #3, then the equation would be 10+12.50h=5+15h.
h will equal 2, and the cost for that number of hours would then be $35.

(x, 7) and (11, 8); m = -1/5<br> Plz help
Kay [80]

Answer:

This tells us that the line with slope -1/5 passes through the two points (16, 7) and (11, 8).  The previously unknown x-coordinate is 16.

Step-by-step explanation:

A line with slope m = -1/5 passes through the points (x, 7) and (11, 8).  Find the value of x.

The slope of the line through these two points is found from the slope formula and is:

        8 - 7

m = ----------- and the value of m is given as -1/5.  Therefore,

         11 - x

           1

m = ----------- =  -1/5

         11 - x

Cross-multiplying, we get (1)(5) = -(11 - x), or 5 = -11 + x.  Then x = 16

This tells us that the line with slope -1/5 passes through the two points (16, 7) and (11, 8).  The previously unknown x-coordinate is 16.

The general form of a circle is given as x^2+y^2+4x - 12y + 4 = 0. A) What are the coordinates of the center of the circle? B) W
Alex_Xolod [135]

Answer:

center = (-2, 6)

radius = 6

Step-by-step explanation:

<u>Equation of a circle</u>

(x-a)^2+(y-b)^2=r^2

(where (a, b) is the center and r is the radius)

Therefore, we need to rewrite the given equation into the standard form of an equation of a circle.

Given equation:

x^2+y^2+4x-12y+4=0

Collect like terms and subtract 4 from both sides:

\implies x^2+4x+y^2-12y=-4

Complete the square for both variables by adding the square of half of the coefficient of x and y to both sides:

\implies x^2+4x+\left(\dfrac{4}{2}\right)^2+y^2-12y+\left(\dfrac{-12}{2}\right)^2=-4+\left(\dfrac{4}{2}\right)^2+\left(\dfrac{-12}{2}\right)^2

\implies x^2+4x+4+y^2-12y+36=-4+4+36

Factor both variables:

\implies (x+2)^2+(y-6)^2=36

Therefore:

  • center = (-2, 6)
  • radius = √36 = 6
