Answer:
1/2 or 0.5
Step-by-step explanation:
Slope (m) =
ΔY/ΔX=
1/2=
0.5
(more in depth)
ΔX = 3 – 13 = -10
ΔY = -5 – 0 = -5
-10/-5 = 1/2 = 0.5
We can drop the absolute value and the signs, and the integer part if they're all the same, and then make a common denominator and check for a decreasing sequence.
10/12, 7/12, 5/12 -- Check decreasing
3 1/3, 3 2/3, 2 2/3 -- nope, increases then decreases
6 5/7, 6 3/7, 5 2/7 - Check, decreasing
11 7/10, 11 6/10, 10 3/10 -- Check, decreasing
Answer: A,C,D
Perimeter = sum of all 3 sides in a triangle
so
x + x - 4 + 12= 26
answer
B. <span>x + x - 4 + 12 = 26</span>
