$15 * 3 days = $45
$57 - $45 = $12
$12 / $0.75 = 16
He interviews 16 people to earn a total of $57.
Answer:
x= 5
Step-by-step explanation:
We are given;
- Base of the triangle as x
- Length of the leg is 4x-5
- An isosceles triangle has two equal legs and a base.
- The perimeter of the triangle is 35 (spelling mistake in the question)
To get the perimeter of a triangle we add the lengths of all sides of the triangle.
Therefore;
x + 4x-5 + 4x-5 = 35
9x - 10 = 35
9x = 45
x = 5
Thus, the value of x is 5
Equation of the perpendicular
y= 2x+6
slope of the perpendicular = 2
slope of the req. line = -1/2
equation of the req. line
y - y1 = m(x - x1)
y - 2 = -1/2(x + 4)
2(y - 2) = -1(x + 4)
2y - 4 = -x - 4
2y = -x
y = (-1/2)x
this is your req. equation of line.
