Answer:
1. 80
2. 18.9
3. 7
4. 146
5. 2
6. 4
Step-by-step explanation:
1. 6+4=10
10×8=80
2. 3.6×4.5= 16.2
16.2+2.7= 18.9
3. 3+2=5
5×2= 10
17-10=7
4. 4×3=12^2
12×12=144
144+2= 146
5. 3+2=5
5×6=30
30÷15=2
6. 5×2= 10
40÷10=4
Answer: Choice C

=========================================================
Explanation:
There are four marked points on the line.
Each point is of the form (x,y)
- The first or left most point is (0,1)
- The second point is (2,2)
- The third is (4,3)
- The fourth is (6,4)
Each of these points is then listed in the table format as shown above.
There are infinitely many other points on the line; however, we only select a few of them to make the table (or else we'd be here all day).
Extra side notes:
- The slope of this line is m = 1/2 = 0.5
- The y intercept is 1 located at (0,1)
- The equation of this line is y = 0.5x+1
Answer: Triangle QRS is an isosceles triangle because QR = RS.
. Step-by-step explanation: Find the length of each side of the triangle using the formula for calculating the distance between two points.
