6.32 units squared
a^2+b^2=c^2
3^2+b^2=7^2
9+ b^2= 49
-9. -9
b^2 =40
b= 2 square root of 10, -2 square root of 10
b=6.32
Answer:
I think this is the answer
Answer:
F-1(x)=7/(x+9)
Step-by-step explanation:
Change F(x) to y so y=7/x -9
Swap variables x=7/y -9
Solve x+9=7/y
7/(x+9)=y
Then change y to F inverse
F-1(x)=7/(x+9)
Thats ur inverse!!!
You start by finding the slope : y2 - y1 / x2 - x1
2 - 8 / 4 - (-16)
- 6 / 20
m = - 3 / 10
Point slope form : y - y1 = m( x- x1 )
You can pick either of the coordinates and substitute them in
POINT SLOPE FORM EQUATION : y - 8 = -3/10 ( x + 16 )
When Javier writes 40 on both accounts they cost him the same amount of money so it should be 41.
Javier needs to write 41 checks for the second bank to beat better
