Two factors of -48 have a difference of 19 the factor with the greater absolute value is positive what is the sum of the factors
MA_775_DIABLO [31]
1). Two factors of -48 => x * y = -48

=> the absolute values of the two numbers may be:

48 and 1

24 and 2

16 and 3

12 and 4

6 and 8 

2). Have a differencie of 19 = > x - y = 19


That makes that the numbers  be + 16 and - 3


Because (+16) * (-3) = - 48

And +16 - (-3) = +16 + 3 = 19.


3) The sum of the factors is +16 + (-3) = 16 - 3 = 13.


So the answer is the option C. 13.

HELPPPPP! Points scored in a basketball game vary directly with shots taken. If a player scores 50 points , and takes 40 shots ,
Veseljchak [2.6K]

Answer:

Points scored in a basketball game vary directly with shots taken.

This means that this question can be solved

by proportions, using a rule of three.

How many would she have scored if she takes 60 shots?

Using a rule of three:

50 points - 40 shots

x points - 60 shots

Applying cross multiplication:

4x = 50 × 60

Divide from both sides

x = 50 × 1.25 = 75

Answer is 75

Step-by-step explanation:

Here is a easier explanation if you didn't understand clearly:

It asked for how many 60 shots would score.

You would look at the first time he scored which is 50 and took 40 shots. Divide them

50 ÷ 40 = 1.25 or 1.5

So now you know each point scores 1.25 or 1.5

Now you multiply 1.25 or 1.5 with how many shots to see how much was scored and in this case 60 shots.

60 × 1.25 or 60 × 1.5

& They both end up equaling just the same, 75.

Hope it made sense :)
