Step-by-step explanation:

h(t) = -16t² + 16t + 12

h(t) = -4(4t² - 4t - 3)

h(t) = -4(2t - 3)(2t + 1)

When h(t) = 0, we have t = 1.5 or t = -0.5.

Hence the zeroes are 1.5 and -0.5.

Step-by-step explanation:

-7 + 4r = -15

+7             +7

4r = -8

divide both sides by 4

r = -2

Hope this Helps!!!

Answer:

r=-2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4r−7=−15

Step 2: Add 7 to both sides.

4r−7+7=−15+7

4r=−8

Step 3: Divide both sides by 4.

4r/4=−8/4

r=−2

Answer:

Step-by-step explanation:

This is how we do it in college, I hope I can be of some help.

First, you multiple 9.6 miles with 5 minutes. Then, you divide your answer with 0.4 miles. Next, you cancel the two mile units because of division and then be left with 120 minutes.

9.6 miles x    5 minutes   =  48 miles x minute = 120 minutes

                      0.4 miles          0.4 miles

Answer:

Question 1: RS=47

Question 2: x=6

Step-by-step explanation:

Question 1:

Step 1: 3x+5=2x+15+6x-37

Step 2: 3x+5=8x-22/2

Step 3: 3x+5=4x-11

Step 4: x=16

Step 5: 2(16)+15=32+15=47

RS= 47

Question 2:

Step 1: 7x+2+25x-14=180

Step 2: 32x-12=180

Step 3: 32x=192  (divide 32 from each side)

x=6

Answer:

Amanda's

Step-by-step explanation:

Given :

3/6 + 2/4

The L. C. M of 6 and 4 = 12

(6 + 6) / 12

12 / 12

= 1

Renne's result = 5/10

Amanda's result = 1 whole

Hence, Amanda's result makes more sense.

Answer:

M= 29/18

Answer:

the download cost for a song is $1 and $11 for a movie

Step-by-step explanation:

According to the questions, the following equations are as follows:

Let us assume the song be x

And, the movies be y

So,

20x + 13y = $163.........(i)

13x + 13y = $156........(ii)

Now solve substract second equation from the first equation

7x = $7

x = $1

And the y value is

20 + 13y = $163

13y = $163 - $20

13y = $143

y = $11

Hence, the download cost for a song is $1 and $11 for a movie

Answer:

45.00 is what she has left

Step-by-step explanation:

Anna has $275.5 left after buying computer.

A percentage is a minimum number or ratio that is measured by a fraction of 100.

Given that Amount saved by Anna each month = $30

Time period = 2.75 years.

1 year = 12 months

2.75 years =  2.75 years x 12 = 33 months

The Amount saved in 33 months = 33 x 30 = $990

She spent 75% of her savings.

Amount spent = 75% of 990

Amount spent = 75% x 990

Amount spent = $742.5

Amount left = Savings - Amount spent

Amount left = 990- 742.5= $275.5

Hecne, Anna has $275.5 left after buying computer.
