Answer:
5 (y + x) or c: 5x+y
Step-by-step explanation:
Simplify the following:
9 x - 3 y - 5 x + 7 y + x + y
Grouping like terms, 9 x - 3 y - 5 x + 7 y + x + y = (-3 y + 7 y + y) + (9 x - 5 x + x):
(-3 y + 7 y + y) + (9 x - 5 x + x)
-3 y + 7 y + y = 5 y:
5 y + (9 x - 5 x + x)
9 x - 5 x + x = 5 x:
5 y + 5 x
Factor 5 out of 5 y + 5 x:
Answer: 5 (y + x)
Rewrite 13/40 as a fraction over 100:
13/40 = (2 • 6.5)/(2 • 20) = 6.5/20
6.5/20 = (6.5 • 5)/(20 • 5) = 32.5/100
32.5/100 = 0.325
which clearly terminates.
It equals DE because it’s obvious they have the same angles and it’s a straight line not a bendy one or anything so it’s ( DE )
Answer:
(x-3)^2
Step-by-step explanation:
y = sqrt(x) +3
To find the inverse , we exchange x and y and then solve for y
Exchange x and y
x = sqrt(y) +3
Now solve for y
Subtract 3 from each side
x-3 = sqrt(y)
Square each side
(x-3)^2 = (sqrt(y))^2
(x-3)^2 = y
The inverse of sqrt(x) +3 is (x-3)^2
