Answer:
3 
Step-by-step explanation:
change 1 
to an improper fraction
1 = 
, thus
× = 
= 3 or 3.57 ( to 2 dec. places )
Answer:
<h2>
88859.375 & f(n)= 28000(0.75)×</h2>
Step-by-step explanation:
using the information on the problem a function can can be made
f(n)= 28000(0.75)×
where x is the amount of years
plug in 4 for x in the equation to get
f(4)=8859.375
Answer:
153.94 is the area
Step-by-step explanation:
If the radius is 7p sqrt of 7p and you have your answer
The area of a circle is pi times the radius squared (A = π r²)
Answer:
The line given is equal to y=-x+7 (Through rearranging)
To find the new line, we substitute the given coordinates (5,8) in the equation without the given y-intersect (+7):
-8=-5+c
c=-3
The line parallel to x+y=7 that passes through the point (5,-8) is y=-x-3
Answer:
Step-by-step explanation:
So,it would be easier to simplify the right equation, so when I say "the right equation", I mean the one I will make right now. It is 8x+9. So the first problem is 8x+9=x+?. Well, if there are no solutions, the slopes have to be the same, and the y-int doesn't matter. So the answer would be + 7x because that will make the x an 8x. If there is one solution, then the slope has to be different. So literally anything but 7x will work. Even constants. If there are infinitely many solutions, then the equations have to be the same. Meaning, you would have to add 7x and 9 to make the left equation the same as the right.
