Find the x-intercepts.

The x- intercepts are the points at which y is equal to zero, so you set the right hand side of your equation equal to zero. You can then multiply both sides by the denominator x^2-4x+3 which leaves you with just 0=2x^2+5x+2. When you factor you get 0=(x+2)(2x+1) which gives you x= -0.5 or -2.

At the end of six weeks, she would have $155 in the bank. At this rate, the expression is as follows: $5 + $10 + $15 + $20 + $25 + $30 = $105. Because she already had $50 in the bank, that is another $50 added to the total. This gives the answer $155.

What is the equation of the line in slope intercept form
slavikrds [6]

Answer:

y = 4/3x +4

Step-by-step explanation:

The first step is to find the slope

We have two points (-3,0) and (0,4)

m = (y2-y1)/(x2-x1)

   = (4-0)/(0--3)

  = 4/(0+3)

  =4/3

Then we need the y intercept (where it crosses the y axis)

It crosses at 4

The form of the equation is

y= mx+b, where m is the slope and b is the y intercept

y = 4/3x +4
