Answer:
i think the answer is -18x^(2)+9x+5
-18x^(2)+9x+5
Subtract 4x^2 from −14x^2
Answer:
A) (3,-8); Reflection
Step-by-step explanation:
The question kind of gave you a hint. Look at how the coordinate point is arranged...
(-y,-x)
That means all positive become negatives and all negatives become positives. This gives you the coordinate of (3,-8).
As for reflection or rotation, the image's coordinates FLIPPED, like how images do in a mirror's reflection.
This means the answer would be A) (3,-8); Reflection.

Parabola equation:

System of two equations:

Answer:
x + y = - 5
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = - x - 5 ( add x to both sides )
x + y = - 5 ← in standard form
Answer would be C
Because I always use the rule of :
B - Brackets
I - indices
D - division
M - multiplication
A - addition
S - subtraction
