She would pay $85.10 in total
74(.15)= 11.1
74+11.1= 85.10
M = (N-2)/N
M = N² - 2N
N² - 2N - M = 0
To find N we need to use quadratic formula.
For our equation x = N, a=1, b= -2, c= -M

Answer:
x = 8
Step-by-step explanation:
complementary means add to 90
6x + 13 + 4x - 3 = 90
10x + 10 = 90
10x = 80
x = 8
And what else, add more detail so i can answer
Answer:
(0.5, 4.5)
Step-by-step explanation:
The easiest-to-graph form is the slope-intercept form. Convert all equations to that form
3x + y = 6
y = -3x + 6 (move 3x)
To graph this, get the y-intercept, just take the b value of the equation (6)
The slope is -3, which is also the coefficient of x. So each time you move 1 over in the x-axis, the y axis drops by 3.
2x + 3 = 4 (this is a vertical line)
2x = 1
x = 1/2
To graph this, just draw a vertical line where x is 1/2
After graphing both equations, the point where the 2 lines intersect is the solution.
