Answer:

2. -x^{2} +3x+15

3. -x^{2} -x+9

Step-by-step explanation:

We add like terms together to simplify

2.  3x²-4x²= -x²     -2x+5x= 3x  6+9= 15  all equal to -x²+3x+15

3.  2x²-3x²= -x²      6x-7x= -x    8+1=9      all equal to -x²-x+9

HELP:. In baseball, the distance from the pitcher's mound to the batter is 60.5 feet. A pitcher can throw the baseball at 121 fe
zheka24 [161]
<h3>Answer:  D. 5 blinks</h3>

=========================================================

Explanation:

First we'll need to find out how long it takes for the ball to go from the pitcher to the batter.

It needs to travel 60.5 feet and does so at a speed of 121 ft/sec

distance = speed*time

time = distance/speed

time = (60.5 ft)/(121 ft per sec)

time = 0.5 seconds

In half a second, the ball is from the pitcher to the batter.

------------

An eye blink is 0.1 second which means we can form this equation

0.1 second = 1 blink

We multiply both sides by 5 to get the "0.1 second" to turn into "0.5 seconds".

So,

0.1 second = 1 blink

5*(0.1 second) = 5*(1 blink)

0.5 seconds = <u>5 blinks</u> which points us to choice D.

Seventy-five balls numbered from 1 to 75 are placed in an urn. One ball is randomly drawn from the urn. What is the probability
kramer
75-31= 44
44/75= 0.58666 or 58.7%

Subtract 31 from 75 since we're figuring out greater than or "equal to" we want to include the number 32 in our equation. If it was only "greater than" 32 then we'd subtract 32 from 75. Then you divide that number(44) by 75, which is all the possible outcomes you could have in this scenario. Move the decimal two places to the right to make it a percentage and you've got your answer.
