3x - 2y = 5
2y = 3x - 5
y = (3/2) x - 5/2
so the gradient (m) of the required line = -1 / (3/2) = -2/3
using the general form
y - y1 = m(x - x1) , m = -2/3 , x1 = -2 and y1 = 1
y - 1 = -(2/3) ( x - (-2))
y = -(2/3)x - 4/3 + 1
y = -(2/3)x - 1/3
multiply through by 3
3y = - 2x - 1
in standard form its
2x + 3y = -1
Answer: 5y-10= -25
5y -10+10= -25 +10
Step-by-step explanation:
N³ - 2n² - 15n = 0
"n"
n (n² + 2n - 15) = 0
n = 0
n² + 2n - 15 = 0
Δ = (2)² - 4(1)(-15)
Δ = 4 + 60 = 64
n' = (-2+8) / 2 = 6/2 =3
n'' = (-2-8) / 2 = -10/2 = -5
Solution:
S {-5 , 0 , 3 }
Answer:

The slope is 35 and it means the technician earns $35 per hour.
Step-by-step explanation:
The technician finds that
- when he works 55 hours during the month, he earns $2,125;
- when he works 30 hours, he earns $1,250.
Let
x = number of hours worked
y = amount of money earned
Find the slope of the linear equation:

Equation of the linear function:

The slope is 35 and it means the technician earns $35 per hour.
