Answer: 3/5
Step-by-step explanation:
First, you need to find the inverse of f(x)=2x+5 .

Then, you'd plug in 8 into that equation, which I got

Answer:
121
Step-by-step explanation:
You are missing a parentheses
Assuming you just mean to close the parentheses
((5-(-4)^2)^2)
The first step is to complete the inside parentheses
PEMDAS
(5-(-4)^2)
Do the exponents first
(5-(16))
-11
Put this in the equation for (5-(-4)^2)
(-11) ^2

Answer:
Bonds: $42,000
Certificates of deposit: $41,000
Step-by-step explanation:
Total invested = Amount in bonds + Amount in CDs
Amount in bonds = Amount in CDs + 1000
Let the amount in bonds = B and the amount in CDs = C
1. 83,000 = B + C
2. B = C+1000
Since the above expression (#2) defines B, you can substitute it for the B in the first equation (#1).
83,000 = C + 1000 + C
Now, you can solve for C.
83,000 = 2C + 1000
82,000 = 2C
41,000 = C
You know that the amount invested in bonds is $1000 greater than the amount invested in CDs, so add $1000 to C and you find B, $42,000.
Answer:
10
Step-by-step explanation:
d = 10
For:
(X1, Y1) = (13, 2)
(X2, Y2) = (7, 10)
Distance Equation Solution:
d=(7−13)2+(10−2)2−−−−−−−−−−−−−−−−−√
d=(−6)2+(8)2−−−−−−−−−−√
d=36+64−−−−−−√
d=1–√00
d=10
