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
