It costs $23 per hour plus a flat fee of $16 for a plumber to make a house call. What is the equation of the form y = mx + b for
Dmitry_Shevchenko [17]

So, we just need to figure out what number means what.


So, the flat fee is $16.  This is going to be charged even for "zero" hours of work.  So, this will be the Y-intercept (also known as the B-Value)


$23 per hour means that as time progresses, you will be charged more.  23 will be our slope since it's price is dependent on time spent.  The slope is also known as the M value.


So, we just plug in our numbers and get

Y = 23x + 16

For circle O, and m∠ABC = 55°. In the figure, ∠ and ∠ have measures equal to 35°.
snow_lady [41]

Answer:

In the figure ∠ABO and ∠BCO have measures equal to 35°.

Step-by-step explanation:

Measure of arc AD = 180-measure of arc CD= 180-125 =55

m<AOB= 55 ( measure of central angle is equal to intercepted arc)

<OAB= 90 degrees (Tangent makes an angle of 90 degrees with the radius)

In triangle AOB ,

< AB0 = 180-(90+55)= 35 degrees( angle sum property of triangle)

In triange BOC ,< BOC=125 ,

m<, BCO=35 degrees

An object is launched from a platform.
Bess [88]

Answer:

60 feet

Step-by-step explanation:

The height, h (in meters), of the object launched from a platform is represented by the equation

h=h(x)=-5x^2+20x+60

where x is the time (in seconds) passed after the launch.

The time of launch is x=0 (0 seconds passed after the launch)

Substitute x=0 to find the height:

h=h(0)=-5\cdot 0^2+20\cdot 0+60=60\ feet

The vertices of ABC are A (-5, 5), B (-2,5), C(-2,3).
bulgar [2K]

Answer:

It will be in the attachment below.

Step-by-step explanation:

Translating a vertex 3 units down and 4 units to the left means that the x coordinate is 4 less than before and the y is 3 less. So, subtract 4 from -5 to get -9; from -2 (twice) to get -6 (twice), and subtract 3 from 5 (twice) to get 2 (twice); from 3 to get 0. So, the new coordinates are (-9, 2), (-6, 2), and (-6, 0). The original shape is in red, and the translated shape is blue.
