What is the value of x in the following proportion? 7/x-5 = 15/x+4

Mathematics

Shalnov [3]3 years ago

For this question you should first add -15/x on both sides of the equation and then add +5 on both sides:
7/x - 15/x = 5 + 4 
-8/x = 9 
so now you can multiply both sides by x:
-8 = 9x 
now you should divide both sides by 9:
-8/9 = x :)))
I hope this is helpful
have a nice day

Using the graph as your guide, complete the following statement.
ollegr [7]

Answer:

positive

Step-by-step explanation:

the discriminant of the function is postive.

because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0

that implies the discriminant is positive.

\Delta = \sqrt{b^2-4ac}

if \Delta > 0 we have 2 distinct real solution

if \Delta we have no real solution but 2 complex solutions

if \Delta = 0 we have 2 identical real solution

PLEASE HALP I GIVE OUT BRAINLIEST
jekas [21]

Since there is two negative signs in the original equation, you need two negative signs in the equivalent one as well.

Because one of the negatives if before the fraction, it doesn't matter if the second negative is on the 13 or on the 12.

The answer is A.
