Answer:

the first one to solve for x is  x=22-y

the first one to solve for y is y=22-x

the second one to solve for x is x=6+y

the second one to solve for y is y=-6+x

Step-by-step explanation:

in the first two you had to subtract y from both sides  of the equation

the second one you had to add y to both sides of the equation to solve for x

but to solve for y you have to move all terms that dont contain y  to the right side and solve

The Mosteller formula for calculating adult body surface area is Upper B equals StartRoot StartFraction hw Over 3131 EndFraction
Anvisha [2.4K]

Answer:

1,75

Step-by-step explanation:

The Mosteller formula is [tex]M=\sqrt{\frac{(172.72)(63.95)}{3600}} = 1.75[/tex]

We know that height is 68 inches and weight 141 pounds

We must remember that 1 inches = 2.54 cm and 1 pound 0.453 kg

This means 68 inches = 172.72 cm and 141 pounds = 63.95

We substitute on the formula

Functions f(x) and g(x) are shown below:.
kobusy [5.1K]
       First we will find the derivative of each function and equate it to zero.
       f` ( x ) = 6 x + 12
       6 x + 12 = 0
       6 x = - 12
       x = - 2
       f ( - 2 ) 0 12 - 24 + 16 = 4
       f ( x ) min = 4
       g` ( x ) = 4 cos (  2 x - π )
       4 cos ( 2 x - π ) = 0
       cos ( 2 x - π ) = 0
       2 x - π = 3π / 2
       2 x = 5π /2
       x = 5π/4
       g ( 5π/4 ) = 2 sin ( 5π/2 - π ) + 4 = 2 ( sin 3π/2 ) + 4 = -2 + 4 = 2
       g ( x ) min = 2 ( this is the smallest minimum value )

Find the measure of Angle 5. . . measure of angle 7 = 2x+15. measure of angle 8 = 3x.
Fed [463]
There exists the same question with an attachment where angle 8 and 7 are supplementary and angle 7 and 5 are vertical angles. From this, the equation that we may derive from the given is,
                              (2x + 15) + (3x) = 180
The value of x is 33. Substitute this value to x of angle 7, 2(33) + 15 = 81. Thus, the measure of angle 5 is also 81 degrees.
