First number is f
Second number is s
f-s=.7
f+s=1
Using elimination, you could solve this.
-1(f-s=.7); eliminate the first number.
-f+s= -.7
f+s=1
2s=.3
s=.15
Now find the second number by plugging it in:
.15+s=1
1-.15=.85
The numbers are .15 and .85.
Answer:
The length is APPROXIMATELY equal to 12.4.
Step-by-step explanation:
Use the converse of the Pythagorean Theorem (
+
=
[where "c" is both the longest side and the hypotenuse]) since a rectangle's diagonals will always cut it into two right triangles:
169-16=153.
≈ 12

If compounding annually, the student will need to put $6,208.85 into the account.
G(4) = 3x^2 - 3x - 9
Since the g(4) would be g(x) if you didn't know the number. So, substitute all of the x's for 4.
g(4) = 3(4)^2 - 3(4) - 9
g(4) = 3(16) - 12 - 9
g(4) = 48 - 3
g(4) = 45
I hope this helps you!
