Answer:
D y=2/3 x +1
y= -3/2 x+2
Step-by-step explanation:
Perpendicular lines have slopes that multiply to -1
The equations are written in slope intercept form
y = mx+b where m is the slope
A 1/5* 5 = 1 not perpendicular
B 2/3 * 3/2 = 1 not perpendicular
C -1/5 * -5 = 1 not perpendicular
D 2/3 * - 3/2 = -1 perpendicular

Step-by-step explanation:
Move decimal twice to the right from were the first zero starts, count the number of zeros and that's your exponent.
Answer: 0.1x - 16 (c)
Explanation: The perimeter is the sum of all three sides of the triangle. Since the three side are 0.5x + 9, 3x, and (-3.4x) - 25, the sum is as follows:
0.5x + 9 + 3x + (-3.4x) - 25 = 0.1x - 16
