Answer:
20.4 kilograms
Step-by-step explanation:
.4 times 51
For lines to be parallel, the slopes have to be the SAME.
For lines to be perpendicular, the slopes have to be the exact opposite. (opposite sign and number)
For example(perpendicular):
slope is 2
the perpendicular slope is -1/2
slope is -4/5
the perpendicular slope is 5/4
12. line a and b are perpendicular
13. Line a: y = 3/5x + 1
Line b: y = 3/5x - 2/5
Line c: y = 4/6 + 5/3x
line a and b are parallel
14. Line a: y = 3x + 6
Line b: y = 6 - 3x
Line c: y = 2/3x + 6
Neither, none of them are parallel or perpendicular
15. Line a: y = -2/3 + 4/3x
Line b: y = -1/4 - 3/4x
Line c: y = 5 + 3/4x
line a and b are perpendicular
Area of a circle=πr²
r=radius=13 cm
area of a circle=π(13 cm)²=169π cm²≈530.93 cm²≈530.7 cm²
Answer: B.530.7 cm²
Answer:
y=6/5x+13
Step-by-step explanation:
6y=-5x+16
Divide by 6
y=-5/6x + 8/3
Slope: 6/5 (opposite reciprocal)
7=-5(6/5)+b
7=-6+b
b=13
The correct answers would be :
2.) 2.6 < 2.7
1.2 < 1.9
10.7 > 10.4
3.) D.
4.) A. (97÷33)
