To find the slope of the line, first find the slope of 3x + y = 5, and then its opposite reciprocal.
3x + y = 5
y = -3x + 5
the slope of 3x + y = 5 is -3.
the slope is -3, so the opposite reciprocal slope is 1/3.
the equation of any line is y = ax + b
to find this line, y = 3, x = -9, and the slope is 1/3.
3 = -9a + b
3 = -9 (1/3) + b
3 = -3 +b
b = 6
substitute a and b into the equation
y = ax + b
y = 1/3x + 6
the equation of the line is y = 1/3x + 6.
Answer: 20%
Step-by-step explanation:
The 150 students in the marching band and 30 of the students play the trumpet. To get the percentage of students that play the trumpet, we divide 30 by 150 and then multiply by 100. This can be written as:
= 30/150 × 100
= 0.2 × 100
= 20%
The percentage of students that play the trumpet is 20%
Answer and Step-by-step explanation:
1. square and 20 ft because each side is 5 ft and 5+5+5+5=20
2. triangle and 25 ft because 12+5+8=25 ft
3. trapezoid but Im not sure what the side lengths are for that one so i dont know what the perimeter is
4. Parallelagram and the same as what happened with number three
5. hexagon and 8+8+8+8+8+8= 48 ft
