It would be the same you would already be dividing by 3 because it’s the denominator and the numerator is 2

Hello from MrBillDoesMath!

Answer:

The equations "are balanced"


Discussion:

Given that

4 + 4 = 8                 => subtracting k from both sides

4 + 4 - k = 8 -k


so the equation shown IS correct. The answer should be the equations "are balanced"


Thank you,

MrB

If a ball is thrown directly upward with a velocity of 50ft/s, it's height (in feet) after t seconds is given by y=50t-16t^2 wha
Tomtit [17]

Answer:

39.0625 ft

Step-by-step explanation:

Since the function is a quadratic representing height, and the coefficient of the t² is negative, the vertex of the parabola will be the maximum height achieved by the ball.  

The general form for a quadratic equation is ax² + bx + c, here a is -16, and b is 50

To find the x coordinate of the vertex, use   x = -b/(2a)

We have x = -50/[2(-16)]

               

                  x = -50/-32

             

                         x= 25/16

Now plug that into the equation to find the y value, which will be the height...

y = 50(25/16) - 16(25/16)²

    y = 1250/16 - 16(625/256)

        y = 1250/16 - 625/16

              y = 625/16

                   y = 39.0625

F(x) = 3x - 1 and g(x) = x2 -x find (f/g(8) answer choices a)-23/6 b)4 c)-4 d)23/6
Lilit [14]

Answer:

all answer wrong with you

Step-by-step explanation:

f(x)=3x-1

f(8)=3.8-1

=24-1

=23

f(g)=x2-x

f(8)=8.2-2

=16-2

=14
