a coordinate plane is a two-dimensional number line where the vertical line is called the y-axis and the horizontal is called the x-axis. And a number line is
a line on which numbers are marked at intervals, used to illustrate simple numerical operations. So how are the related........?
(x^2 +5x+2.5^2) +4+5
(x+2.5)^2+9
vertex -2.5,9
Answer:
-3.8, 3
Step-by-step explanation:
The solution to a system is where the graph cross each other. If you look to where they intersect to the left of the origin, where x is negative, it appears that they intersect ALMOST at -4, but not quite. So -3.8 is going to have to do since we don't have the equations of either graph to find the exact values of x. To the right of the origin, where x is positive, the graphs cross where x = 3..
After 3 years the computer will be valued at 3711.5. I'm sure you can round it up to 3712.
Hope this helps :)
$3.75 would be rounded up and changed to $4
