The answer is "A'B'C'D' is obtained by rotating ABCD counterclockwise 90degrees about the origin and then reflecting it over the x-axis"
I got the answer by trying out each option, since none of the first three gave me result expected, I knew it was the fourth one.
6+(-5) is the same as 6-5 because when adding negative 5 to 6 you are basically subtracting a regular 5 from 6. So the + in front of the parenthesis makes the 5 a positive: 6+(-5) —— 6-5

Answer:
60 m/h
Step-by-step explanation:
1. the basic formula is Time=Distance/Speed;
2. total time is time1 (for 84 miles)+time2 (for 130 miles)=time (4 hours);
3. the time for the first 84 mi. is time1=84/S;
4. the time for the rest 130 mi. is time2=130/(S-10);
5. using all the data of items 2-4, it is possible to substitute into the basic formula and resolve an equation:


note, that the value of speed has one condition: s>10. It means, the only value is true: 60 miles per hour.
To solve for x, you simplify both sides of the equation and then isolate the variable.
<em>10x + 12 = $72.00</em>
<em>x = 6</em>
