Answer:
(8,6)
Step-by-step explanation:
the difference between the end point and mid point is 3 for x and 5 for y. If we add 3 to the x in the mid point and 5 to the y in the mid point we get (8,6). Hope this helps!
The correct answer is: [F]: "rational" .
________________________________________________
It is not an "integer" because it is a "decimal value".
It is not "irrational" because the decimal value terminates and does not repeat.

Answer:
Step-by-step explanation:
Lin drew a triangle and a dilated triangle with a scale factor of .
That means image of the original triangle is smaller than the preimage.
1). Center of dilation will be point A.
Since, triangle ACB has been reduced to form triangle ADE by a scale factor of
Scale factor = =
AD =
So the center of dilation is point A.
2). Since triangle ADE is half of the triangle ACB, triangle ACB is preimage (original) and triangle ADE is an image after dilation.
Answer:
Δ = 349
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 ) , then the discriminant is
Δ = b² - 4ac
9x² + 5x - 9 = 0 ← is in standard form
with a = 9, b = 5 , c = - 9 , then
b² - 4ac
= 5² - (4 × 9 × - 9)
= 25 - (- 324)
= 25 + 324
= 349
