dalvyx [7]

Answer:

The function is:

f(t) = -16t^2 + 50t + 3

Step-by-step explanation:

Given

height = 3ft

velocity = 50ft/s

acceleration = -16ft/s^2

Required

The function

Let t represents time;

So, we have:

f(t) = acceleration * t^2 + velocity * t + height

So, we have:

f(t) = -16* t^2 + 50* t + 3

f(t) = -16t^2 + 50t + 3

6х + 4ув 32<br>-6х + 4 y = 8​
AveGali [126]

Answer:

The Solution set is (x,y){(2,5)}

Step-by-step explanation:

The given equation is:

  6x+4y=32

 -6x+4y=8

We will use the elimination method:

By this method we will eliminate the variable x.

6x+4y=32

-6x+4y=8

________

      8y=40

Divide both the sides by 8

8y/8=40/8

y=5

Now substitute the value of y in equation 2:

-6x+4y=8

-6x+4(5)=8

-6x+20=8

Move the constant value to the R.H.S

-6x=8-20

-6x= -12

Divide both the terms by -6

-6x/-6 = -12/-6

x= 2

The Solution set is (x,y){(2,5)}....

Four more than three times n equals -5
Verizon [17]
3n+4=-5

do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.

-5-4=-9

since 4-4=0, we can take 4 out of the equation. now you have:

3n=-9

now divide -9 by 3

-9/3=-3

n=-3

hope this helps :)
