False. It’s a quadrilateral.
Answer:
e) Hence 2, -7 are roots of the equation X² + 5X - 14 = 0
Step-by-step explanation:
given equation : X² + 5X - 14 = 0
⇒ X² + 7X - 2X - 14 = 0
⇒ X·(X + 7) - 2·(X + 7) = 0
⇒ (X + 7)·(X - 2) = 0
⇒ X = -7, X = 2
<u>Hence 2, -7 are roots of the equation X² + 5X - 14 = 0</u>
Answer:
Below
Step-by-step explanation:
The equation of a circle is written as:
(x-a)^2 + (y-b)^2 = r^2
● ( a,b) are the coordinates of the center . Here (0,-2)
● r is the radius (here 12)
So the equation is:
x^2 + (y+2)^2 = 12^2
Answer:
y = 3x - 5
Step-by-step explanation:
Slope m = 3
Using (1,-2)
Slope-intercept: y = mx + b
-2 = 3(1) + b
-2 = 3 + b
b = -5
then y = 3x - 5
