9. Solve for x: 2x – y = (3/4)x + 6.

Answers

Answer:

x = 4(y + 6)/5

Step-by-step explanation:

2x - y = (3/4)x + 6

2x - (3/4)x = y + 6

(8x - 3x)/4 = y + 6

5x/4 = y + 6

5x = 4(y + 6)

5x = 4y + 24

x = (4y + 24)/5

Therefore, x = 4(y + 6)/5

A rocket is launched upward so that its distance, in feet, above the ground after t seconds is represented by the function below. What is its maximum height? h(t)=−16t2+320t

Answers

Answer: 1600 feet.

Step-by-step explanation:

Given : A rocket is launched upward so that its distance, in feet, above the ground after t seconds is represented by the function $h(t)=-16t^2+320t$

To find : its maximum height.

First we differentiate the given function , we get

$h'(t)=(2)(-16)t+320=-32t+320$

Put $h'(t)=0$ , we get

$-32t+320=0\n\n\Rightarrow\ t=(-320)/(-32)=10$

Hence, at t=10 , rocket achieves its maximum height.

$\text{Maximum Height =}h(t)=-16\left(10\right)^(2)+320\left(10\right)\n\n=-1600+3200=1600$

Hence, its maximum height = 1600 feet.

Answer:

1600 ft

Step-by-step explanation:

We are given that a rocket is a launched upward so that its distance(feet) above the ground after t seconds is represented by the function

$h(t)=-16t^2+320t$

We have to find the maximum height.

Substitute h(t)=0

$-16t(t-20)=0$

$t=0,t-20=0\implies t=20$

When t=0 it means the rocket is at ground launch.

When t= 20 s.

Total time taken by rocket=20 s.

Half of the time taken to reach maximum height and half of the time taken to reach ground back.

Therefore, time taken by rocket to reach maximum height= $(20)/(2)=10s$

Substitute t=10 in given function

Then we get

h(10)=-16(10)^2+320(10)=-1600+3200=1600 ft[/tex]

Hence, the maximum height=1600 ft

What is the slope of the line?

Answers

Answer:

-2

this eq. can be simplified to -

y = 5 - 2x

we know that the coefficient of x is the slope

therefore , -2 is the slope

Answer:

A. -2

Step-by-step explanation:

Arrange to y-intercept form:

-4x + 7 = 2y - 3

7 = 4x + 2y - 3

7 + 3 = 4x + 2y

10 = 4x + 2y

10 - 2y = 4x

-2y = 4x - 10

y = -2x + 5

As you can see, -2 is the slope of the equation.

I have no idea what to do. Pls help me

Answers

for the first one all u do is 5 times 2 = 10 + 2 = 12. the denominator stays the same so 12/5. then you do the same thing to the other fraction. 3 times 1 = 3 + 2 = 5. the denominator stays the same so your fraction is 5/3. so the answer is 12/5 times 5/3.

hope this helps !
