♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

f( - 4) = 4( - 4) + 9 =  - 7

_________________________________

f( - 2) = 4( - 2) + 9 = 1

_________________________________

f(0) = 4(0) + 9 = 9

_________________________________

f(2) = 4(2) + 9 = 17

_________________________________

Thus ;

R = { - 7 , 1 , 9 , 17 }

The correct answer is (( D )) .

Answer:

\frac{1}{2} blocks

Step-by-step explanation:

If it takes 15 minutes to walk 7 1/2 blocks, it should be 15:17\frac{1}{2}

The left side is minutes and the right side is the number of blocks

15:17\frac{1}{2}

 1: ?  Since we are figuring out how many blocks he can walk in a minute, the left side is 1 and the right side is a question mark because we have not figured it out yet.

15: 17 \frac{1}{2}    Divide by 15 on both sides because that is the "distance" from 15 to1

 1 : ?

1: \frac{1}{2}

So the answer is \frac{1}{2}

What is 5/6 times 7/4
garik1379 [7]
To solve this, we simply need to multiply the numerators and the denominators together.

\frac{5}{6} * \frac{7}{4} =  \frac{5*7}{6*4} = \frac{35}{24}

Which is our final answer, as it cannot be simplified further.
\frac{5}{6} times \frac{7}{4} is \frac{35}{24}.
Hope that helped! =)

postnew [5]

Answer:

318 feet.

Step-by-step explanation:

We have been given that a girl drops a ball off a cliff into the ocean. The polynomial h(t)=-8t^2+350 gives the height, in feet, of the ball t seconds after it is dropped from a 350 ft tall cliff. We are asked to find the height in feet after 2 seconds.

To find the height after 2 seconds, we will substitute t=2 in our given equation as:

h(2)=-8(2)^2+350

h(2)=-8(4)+350

h(2)=-32+350

h(2)=318

Therefore, the height will be 318 feet after 2 seconds.
