Answer:
y=-x+3
Step-by-step explanation:
The general slope-intercept equation of a line is y=mx+b where m is the slope and b represents the y intercept. y and x are simply a point the line passes through. In this case, y=x-5, meaning m=1 and b=-5.
In order to find the perpendicular slope, we should take the current slope's <u>negative reciprocal</u>. We have:
Therefore, our perpendicular slope is -1. We now have equation:
We can plug in the known values of the point (-1,4) to solve for b.
If we now put what we found together, we have equation

Answer: none
1) combine like terms: 4x + 8 = 4x - 13
2) Add 13 to both sides (addition property of equality)
3) Subtract 4x from both sides (subtraction property of equality)
4) 21 does not equal 0
A) x + y = 17
B) x - y = 27
Adding both equations:2x = 44
x = 22
y = -5
Answer:
1222 billion dollars.
Step-by-step explanation:
To find the total increase from 1960 to 2010, we need to find the growth of each decade and sum them all:
In the period 1960-1970, we have x = 1, and the growth is:
In the period 1970-1980, we have x = 2, and the growth is:
The growth in the following 3 periods are:
So the total growth in the period 1960 - 2010 is:
Rounding to the nearest billion dollars, we have a total of 1222 billion dollars.
6+z=10x-2
6+z=-20
Z=-20-6
Z=-26
