Answer:
8
Step-by-step explanation:
Eric's salary: y=75x+1400
Nancy's salary: y=250x.
Solve the system of equations to get 8.
Since the equation we're looking for is parallel to another line, we can "steal" the second line's slope and use it in our equation.
Point-slope formula:
y - y1 = m(x - x1)
y - 2 = 2(x-(-1))
y - 2 = 2(x+1)
Solve for y to put into slope intercept form:
y - 2 = 2x + 2
y = 2x + 4
Knowing that an hour has 60 minutes, add 25 minutes to 9:55 to get 10:20. Another way to think of this is by adding 25 to 55 to the base of 60. Assuming that he only had to mow the front and back yard, add 45 minutes to 10:20 to get your final answer.
The final answer should be: 11:05 am.

Answer:
10x -30y = 3
Step-by-step explanation:
In general form, you can start by swapping the x- and y-coefficients, negating one of them. To find the new constant for the equation, substitute the values for the given point
2x -6y = 2(-3.9) -6(-1.4)
2x -6y = 0.6
Multiplying by 5 will make the numbers be integers, so will put the equation in standard form.
10x -30y = 3
Ok so remember
if a+bi is a root, then a-bi is also a root
since 2i is a root, -2i is also a root
use synthetic division and the fact that when we divide by 2i and -2i, we have to get all real coeficients and end witha zero at the end
I will show the division in the attachment
we find m=8
we then find th resulting equation that is x^2-2x+2=0
quadratic formula
x=

x=1+i or 1-i
m=8 and the other roots are
x=-2i, 1+i, 1-i
