Answer:
x=1.25
Step-by-step explanation:
We want to solve by graphing.
We let and also
.
We graph both equations to obtain the graph shown in the attachment.
The two graphs intersect at (1.25,0.74)
Therefore the solution to is the x-coordinate of the point of intersection of the two graphs which is x=1.25.
Answer:
2/3
Step-by-step explanation:
A line perpendicular to another line has a opposite reciprocal slope.
For example, if a line has a slope of 5, then the perpendicular line will have a slope of -1/5.
First, put the formula into slope intercept form:
3x + 2y = 18
2y = -3x + 18
y = -3/2x + 9
Because this line has a slope of -3/2, the perpendicular line will have a slope of 2/3.

Answer:
141
Step-by-step explanation:
The interior angles of a polygon with <em>n</em> sides is 180(<em>n</em> - 2) and the polygon has 7 sides, so the sum of its interior angles is 180(7 - 2) = 180(5) = 900.
125 + (x + 7) + 107 + (x - 15) + x + 131 + 122 = 900
Combining like terms,
3x + 477 = 900
3x = 423
x = 141
Year. Population
1995. 4,500
2000. 15% increase from 4,500
15% of 4500=0.15•4500=675
4500+675=
5,175
2005. 4% decrease from 5,175
4% of 5175=0.04•5175=207
5175-207=
