Answer:
The coordinates of the reflected triangle are 
, 
and 
.
Step-by-step explanation:
Let be a point 
, reflections across x- and y-axes are represented by the following operations:
x-Axis reflection:
y-Axis reflection:
If we know that 
, 
and 
, the coordinates after both reflections are, respectively:
The coordinates of the reflected triangle are , and .
Answer:
A
Step-by-step explanation:
The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is 
where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.
This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.
Let's solve this problem step by step.
28=8b+13b-35
Step 1: Bring 35 to 28.
28=8b+13b-35
+35 +35
63=8b+13b
Step 2: Add 8b and 13b.
63=21b
Step 3: Divide both sides by 21.
63/21=21b/21
So, the answer for this problem is 3=b.
She would make about 17.35 because $850 divided by 49 is 17.3469388 rounded is 17.35
