Answer:
what?? the question is not clear.....
The slopes of lines perpendicular to each other are opposite reciprocals. So, if you are given that the slope of a line is 3 and need to find the slope of a line perpendicular to that line, you'd flip that number around and negate it, leaving you with -1/3.
To find the slope of the given line, first get it into slope-intercept form (y - mx + b, where m is the slope and b is the y-intercept).
3y = -4x + 2
y = -4/3x + 2/3
The slope is -4/3. To find the slope of a perpendicular line, find its opposite reciprocal. It is 3/4.
Answer:
3/4 (the first option)
Answer:
area = 11 17/21 cm²
Step-by-step explanation:
area = length x width
area = 2 2/7 x 5 1/6 = 16/7 x 31/6 = 496/42 = 11 34/42 = 11 17/21 cm²
Answer:760ft2
Step-by-step explanation:
Area of first triangle = 1/2bh = 1/2*8*15=60ft2
Area of second triangle = 60ft2
Area of bottom rectangle =20*15=300ft2
Area of top rectangle = 17*20=340 ft2
Total surface area =60+60+300+340
=760ft2
