Answer:

1

Step-by-step explanation:

When adding a negative and a positive number, subtract the biggest number from the smallest (ignore the signs), so :

6-5=1

After you have your answer, keep the symbol of the bigger number (pay attention to the signs now). Since positive 6 is greater than negative 5, keep the positive. Add this symbol to the answer, making the answer positive.

-5+6=1

49 = -5n – 2n<br> I think I know the answer but just wanna be sure?
Svetach [21]

Answer:

n = -7

Step-by-step explanation:

49 = -5n - 2n

combine like terms

-5 - 2 = -7

49 = -7n

divide both sides by -7

49/-7 = -7n/-7

49/-7 = n

49/-7 = -7

-7 = n

F(x)=(5x+3)(x−2)(3x+7)(x+5) has zeros at x = -5, x = -7/3, x = 2
musickatia [10]

The sign of f on the interval -7/3 < x < -3/5 is always positive.

<h3>How to solve for the sign on the interval</h3>

We have the equation

(5x+3)(x−2)(3x+7)(x+5) > 0

Now when f(x) > 0

Then -7/3 < x < -3/5

This would tell us that the sign would become positive when it changes from the less than to greater than sign

<h3>Complete Question</h3>

f(x)=(5x+3)(x-2)(3x+7)(x+5) has zeros at x=-5, x=-7/3, x=-3/5, and x=2

What is the sign of f on the interval -7/3<x<-3/5?

answer choices

f is always positive on the interval

f is always negative on the interval

f is sometimes positive and sometimes negative on the interval

f is never positive or negative on the interval

give answer here:

<u><em>These are Function (7,2), (1,1), (8,1), (4,2), (3,11) These are not Functions (7,2), (1,1), (8,1), (4,2), (1,11) </em></u>

step-by-step explanation:

<u><em>The first set is a function i know this because for example the inputs which are 7,1,8,4,3 are buyers for a car and the output is 2,1,1,2,1 1 and those are the cars but the input is different buyers, The 2nd one has two of the same inputs which means the same buyer is buying two cars which is not fair so it makes it a non function.</em></u>
