-5x² -4x +8  

remove parentheses and collect terms.

 (-2x² +3) -(3x² +4x -5)

 = -2x² +3 -3x² -4x +5

 = (-2-3)x² -4x +(3 +5)

 = -5x² -4x +8

Answer:

  -5x² -4x +8

Step-by-step explanation:

Eliminate parentheses and collect terms.

  (-2x² +3) -(3x² +4x -5)

  = -2x² +3 -3x² -4x +5

  = (-2-3)x² -4x +(3 +5)

  = -5x² -4x +8

Describe how you can tell that a fraction is reapeating and not terminating
GREYUIT [131]
<span> First, reduce the fraction to lowest terms, e.g. 8/6 = 4/3.

Look at the denominator. Split it into its prime factors. If its prime factors only consist of 2's and 5's, then it will be terminating.

Examples:
16 = 2 x 2 x 2 x 2, so terminating
25 = 5 x 5, so terminating
2000 = 2 x 1000 = 2 x (2 x 5) x (2 x 5) x (2 x 5), so terminating
12 = 2 x 3, so repeating (has prime factor 3, which is not 2 or 5)
13 = 13, so repeating (has prime factor 13, which is not 2 or 5)  Hope this helps!!

Can someone help me with this quickly please.​
ELEN [110]

Answer:

See explaination

Step-by-step explanation:

Probability is the number of desired outcomes over the total outcomes.

1) You want to find Oranges, so that is your desired outcome:

There are 4 oranges in the bowl.

Now sum up all the fruits to get the total:

9+4+7+3+6 = 29

Therefore you have 4/29

2) Same idea, count the peaches and put it over total:

3/29

3) This time, you still want to use the same idea, but its just your desired outcomes that have increased. So instead of just having one fruit, now you want to add the total of 2 fruits as your desired outcome.

(9+4)/29

= 13/29

4) To find the probability of a fruit other than a plum, you can use complementary counting. Since the maximum probability is one, we can find what we dont want, and the outcome of that subtracted from one must be the results that we want.

So a plum is 6/29

1-6/29 = 23/29

5) Same idea as what is used in problems 3 and 4, just a combination of the 2.

(4+3)/29

1-7/29

= 22/29

Which is a greater slope 3 or -4
castortr0y [4]

Answer:

3 is greater than -4, but the line with slope -4 is steeper than the line with slope 3.

Step-by-step explanation:

3 is greater than -4, so strictly speaking, a slope of 3 is greater than a slope of -4.

On the other hand, the steepness of a line depends on the absolute value of the slope.

|3| = 3

|-4| = 4

Since 4 > 3, the line with slope -4 is steeper than the line with slope 3.

Answer: 3 is greater than -4, but the line with slope -4 is steeper than the line with slope 3.
