P- it is amount of exercises
average= \frac{exercises}{hour}
Monday average= \frac{p}{3h}
Tuesday average= \frac{p}{2h}
If we take into account both days and calculate average from Monday and Tuesday ( we sum 3h on Monday and 2 hours on Tuesday and p exercises on Mon and p exercises on Tuesday):
Monday and Tuesday average=\frac{2p}{5}

Solve y = f(x) = (2x+1)^1/2<br><br> &amp; g(x) = x-1
snow_lady [41]

Answer:

f(x) = x = \frac{y^{2} - 1}{2}

g(x) = 1

Step-by-step explanation:

y = (2x + 1)^1/2

y^{2} = 2x + 1

y^{2} - 1 = 2x

\frac{y^{2} - 1}{2} = x

y = x - 1

y + 1 = x

write the standard equation for the circle with the center at (4,1) and passing through the point (0,1)
Airida [17]
Without needing the distance formula

from 4,1 to 0,1, you move the "x" from 4 to 0, over the same "y" value of 1, so is just 4 units long, from the center to an endpoint, and the chord that stems from the center to an endpoint is the radius, so r = 4

\bf \textit{equation of a circle}\\\\ &#10;(x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2&#10;\qquad &#10;\begin{array}{lllll}&#10;center\ (&{{ h}},&{{ k}})\qquad &#10;radius=&{{ r}}\\&#10;&4&1&4&#10;\end{array}

10. Write the equation of the line with a slope of -1 and passes through the point (-13,0). Put in Standard
shepuryov [24]

Answer:

Step-by-step explanation:

slope m  = -1;   (-13,0)

y - y1 = m (x-x1)

y - 0 = (-1)* (x - [-13] )

  y  = (-1)* (x + 13)

   y = -1*x  + (-1)*13

   y =  -x -13

Solve algebraically for the positive value of x, x _ 0, and check: 2x+5/7=1/x
kati45 [8]

<span>The solution would be like this for this specific problem:

</span>

(2x+5)/7 = 1/x
(2x+5) x = 7
2x² + 5x - 7 = 0
( x -1) ( 2x + 7) = 0
x = 1 ( Omit x = -7/2)

<span>I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.</span>
