I think that it's E tbh cuz it's that same thing that the question is asking
When a line is reflected along the x axis, the sign of the x coordinate of the points on the line remains the same while that of the y coordinate is reversed. Therefore,
For point A, the x coordinate is - 2 and the y coordinate is - 1. After relection over the x axis, it becomes
(- 2, - -1)
= (- 2, 1)
For point B, the x coordinate is - 1 and the y coordinate is - 3. After relection over the x axis, it becomes
(- 1, - -3)
= (- 1, 3)
The coordinates after reflection are A(- 2, 1), B(- 1, 3)
Answer:
<u>It</u><u> </u><u>is</u><u> </u><u>2</u><u>0</u><u> </u><u>white</u><u> </u><u>marbles</u>
step by step explanation:
Fraction of the yellow marbles:
let total number of marbles be x :
Total marbles = 80 marbles
for white marbles:
<em>5</em><em>5</em><em>+</em><em>8</em><em>0</em>
<em>1</em><em>3</em><em>5</em>

ANSWER
Brayden should have expanded the parenthesis first.
EXPLANATION
The expression Brayden is trying to simplify is
To simplify this expression, the first thing to do is to expand the perfect square to obtain:
We can now distribute the negative to the terms in the parenthesis.
