Rearrange x = 3g + 2 to make g the subject.
Kisachek [45]

Answer:

g = \frac{x-2}{3}

Step-by-step explanation:

x = 3g + 2 ( subtract 2 from both sides )

x - 2 = 3g ( divide both sides by 3 )

\frac{x-2}{3} = g

Equation 1: 8x+2y=308x+2y=30
Tems11 [23]

Answer:

Part a) We should try to eliminate the y's because the coefficients are the same

Part b) The solution is the point (6,-9)

Step-by-step explanation:

Part a) Which variable pair should we try to eliminate?

we have

8x+2y=30 ----> equation 1

7x+2y=24 ----> equation 2

Solve by elimination

We should try to eliminate the y's because the coefficients are the same

Part b) What is the solution to the system?

Multiply equation 2 by -1 both sides

-1(7x+2y)=-1(24)

-7x-2y=-24 -----> equation 3

Adds equation 1 and equation 3

8x+2y=30\\-7x-2y=-24\\-------\\8x-7x=30-24\\x=6

Find the value of y

8x+2y=30[/tex[tex]8(6)+2y=30

2y=30-48

y=-9

The solution is the point (6,-9)

The height h in feet of the ball t seconds after it is kicked can be modeled by the function h = -4t (4t - 11). How long is the
Vaselesa [24]

Answer:

t₁  = 2,75 sec

Step-by-step explanation:

The ball will get h maximum when  dh/dt ( its vertical component of the speed is equal to 0. At this moment the ball has flown half of the total flight time

Then

h(t)  = - 4t * ( 4*t - 11 )

h(t)  = - 16*t² + 44*t

Taking derivatives on both sides of the equation we get:

dh/dt  =  - 32*t  +  44

dh/dt  = 0     ⇒   -32*t  + 44 = 0

t  =  44/32     ⇒   t = 1,375 s

So twice this time

2*t   =  2 * 1.375

Total time t₁  = 2,75 sec
