The third one I think so ....

Btw it's an inequality not an equation
The score of Raven is 9 points
<em><u>Solution:</u></em>
Let the point scored by bangal be"x"
Score of Raven = 40 points
Given that,
The ravens scored 13 more than three times number points that the bangals scored in their last game
Score of raven = 13 + 3(score of bangal)
40 = 13 + 3x
Solve the above equation for x
3x = 40 - 13
3x = 27
x = 9
Thus the score of Raven is 9 points
Answer:
- Center = (3, 0)
- Radius = 3
- Graph = see below
Concept:
Here, we need to know the idea of the circle equation.
Circle equation: (x - h)² + (y - k)² = r²
(h, k) = center
r = radius
x = variable
y = variable
Solve:
<u>Given expression </u>
(x - 3)² + y² = 9
<u>Find the point of the center</u>
(h, k) = 
<u>Find the length of the radius</u>
r² = 9

Hope this helps!! :)
Please let me know if you have any questions
<span>so your equation would be 2x-3=-1 then your answer would be -1
