What is the solution set of the equation (x+9)(x+4)=0

Mathematics

Alinara [238K]3 years ago
8 0

Answer:

The set of solution is {-9,-4}

Step-by-step explanation:

*  We use this result: A.B=0 , that means A=0 or B=0.

*  (x+9)(x+4)=0, then x+9=0 or x= - 9

Or x+4=0, x= - 4.

This equation has 2 solutions: - 9 and - 4.

Hope that useful for you.

From the diagram, we know that it is an angle that adds up to 360

So

x+4x+2x+10+5x+50=360


Gather like terms

12x+60=360

Move sixty to the other side as a negative number

12x=300

Divide both sirs by twelve

x is equal to 25

AOB is 2x+10

Sub x in 2*25+10

AOB is 60

BOC is 5x+50

5*25+50, which is 175

BOD is x+2x+10

Which is 3x+10

Sub x

3*25+10 which is 85

Which of the functions below could have created this graph?
Yuri [45]
It's A), because if the highest exponential would've been uneven, the graph would go up, then down, but as you can see it kinda resembles a parabola, making it one out of A) and B)
as you can see, the graph crosses the system at (0/0), so it can't be C), due to it's constant at the end, being "+1"
so it's A)
