Answer:
y intercepts= 0 x intercepts= none
nation:
The 2 funtions above the x axis do not intercept with the y-axis or the x-axis. They just hover above it, but never atcually touch it.
The function bellow the x-axis only intercepts the y-axis at 0,0
The rule of 72 says to divide 72 over the interest rate without the percent sign attached to it. This means we divide 72 over 9.6 to get 72/9.6 = 7.5
So the money doubles every 7.5 years. When another 7.5 years rolls around, a total of 2*7.5 = 15 years has gone by. At this point the money is roughly 4 times that of the original amount deposited.
<h3>Answer: choice B</h3>
5x+4y=16 y=3/5x-3
y=mx+b <------ slope-intercept form
5x+4y=16
-5x -5x
============
4y=-5x+16
--------------
4
============
y= -5/4+4
Slope is -5/4
y-intercept is 4
y=3/5x-3
slope is 3/5
y intercept is -3
I can't do the graph but I'm sure you can figure it out!
Hope I helped.
16x+3y=251 and 8x+4y=148 then you set them up to each other and cancel one coefficient through elimination or find out what X or Y equals and substitute into either equation
The best I can do is determine the roots:
3.5 plus 3.5707 i and
3.5 minus 3.5707 i
