What is the solution to the system of equations below? Y=-4/5x-6 & y=-30

Ainat [17]

So when you are trying to find the solution to the system of equations make sure that you have it where y= -4/5x-6 and y= -30 are written like this:

-30=-4/5x-6

And then solve for x:

Add 6 on both sides.

-24=-4/5x

Then multiply by the reciprocal of -4/5.

-5/4*-24=-5/4*-4/5x

x=30

But then you are gonna want to plug 30 in for x in y=-4/5x-6 to make sure that it is the same as y=-30.

I believe in the question it only states 4% interest without any time factor so therefore it would be $10 interest for 1 month or 8 months

Is this a trick question?

Mama L [17]

Answer:

(1,-3), (2,-2)

Step-by-step explanation:

The graph passes through (3, -1) and (0, -4)

The slope is:

(-4 - (-1))/-3 = -3/-3 = 1

The y-intercept is given: -4

The line is:

y = x - 4

See the graph

The points plotted as well and those on the line are:

(1,-3)
