I believe 5 is 3 inches per year because 57 minus 40 and 1/2 is 16 and 1/2, so you divide 16 and 1/2 by 5 and 1/2 which equals 3, so 3 inches per year
Answer:
(4, 6)
Step-by-step explanation:
90 degree goes counterclockwise so
(6,-4) becomes( 4, 6)
(x,y) rotation 90 or -270 is (-y,x)
A) We can first start with the how: our equation is 2x+y=3. First, subtract 2x from each side. We get y=-2x+3. Our Y variable is isolated.
B) Now we can describe which points our equation goes through. One of them is obvious in our form, and that is (0,3) or our y-intercept. Another 2 would be branching off that line, such as (1,1) or (-1,5)
C) To make our system inconsistent, we can easily make another equation, with same slope, but the y-intercept has to be different. Our equation can be y=-2x+2, y=-2x+4, or even y=-2x+3.00000001.
Hope this helps you.
Percent decrease=(decrease)/(original) converted to percent
change=120 to 52
120-52=68
change or decrease=68
original=120
68/120=0.5666666=56.6666%
about 57%
