Answer:
9+4n-1=
Step-by-step explanation:
first you substitute n for 3
next you do 4*n=12
then you finish the problem
with order of operations
4*3=12
12+9=21
21-1=20
20 is your answer

Y=-2x+2 and y=x^2-3x.
If there are solutions the x and y values are equal so we can say y=y:
x^2-3x=-2x+2 add 2x to both sides
x^2-x=2 subtract 2 from both sides
x^2-x-2=0 now factor...
x^2+x-2x-2=0
x(x+1)-2(x+1)=0
(x-2)(x+1)=0
So there are two solutions, when x=-1 and 2
Using y=-2x+2 we can find the corresponding y values for the solutions...
y(-1)=-2(-1)+2=2+2=4, y(2)=-2(2)+2=-4+2=-2 so the two solutions are the points:
(-1,4) and (2,-2)
Y= {2,4,6,8,10,12,14,16,18,20}<br>
X={4,8,12,16,20,24,28,32,36,40}<br>
Find the difference Y-X
olganol [36]
Answer:
difference between Y-X = 2
Step-by-step explanation:
you can subtract 2-4 in Y and also in X 4-8
as the difference between 2 (2-4, 4-8) number would be 2. therefore difference is 2
