X = 1, since they intersect at (1,6) and are thus equal at that point
we have that
*-------------------------*--------------------------------*
E F G
EF=2x-12
FG= 3x-15
EG=23
we know that
EF + FG = EG
so
[2x - 12] + [3x - 15] = 23 simplify
5x - 27 = 23 add 27 to both sides
5x = 50 divide both sides by 5
x = 10
EF=2x-12-------> EF=2*10-12-------> EF=8
FG= 3x-15------> FG=3*10-15------> FG=15
therefore
the answer part a) is
the value of x is 10
the answer part b) is
the value of EF is 8
the answer part c) is
the value of FG is 15
1 trillion is 10^9.
Thus, 21 1/2 trillion is 21 1/2 times 10^9, or 2.15 times 10^10
Hope this helps. If not, ask for clarification.
Answer:
(10, 1)
Step-by-step explanation:
It tells you that when you translate it you add 2 to the x-coordinate and subtract 7 from the y-coordinate. This means that the point E, (8, 8), would become (8 + 2, 8 - 7) or (10, 1).
Answer:
Anything
Step-by-step explanation:
5n - 10 = 5n - 10
It doesn't matter what you put in for n, the equality can never be anything but an equality.
Suppose n = 10,000,000
Then 5*10,000,000 - 10 = 5*10,000,000
