1) name the variables:
- amount in account 1 "a"
- amount in account 2 "b"
2) trtanslate the statements into equations:
<span>- the
difference between account 1 and account 2 is $100.
=> a - b = 100
- if she uses 3/8 of
account 1 and 7/8 of account 2, Dawn will have a down payment of $2,000.
=> (3/8)a + (7/8)b = 2000
3) solve the system of equations
(1) a - b = 100
(2) (3/8)a + (7/8b) = 2000
Steps:
- multiply equation (1) by 7 and equaton (2) by 8
=>
(1) 7a - 7b = 700
(2) 3a + 7b = 16,000
- add the two equations
=>
7a + 3a - 7b + 7b = 700 + 16,000
- combine like terms:
10a = 16,700
- divide by 10:
a = 16,700 / 10 = 1670
- use equation (1) to find b:
a - b = 100 => b = a - 100 = 1670 - 100 = 1570
Answer: Dawn has $ 1670 in account 1 and
$ 1570 in account 2.

Take out the constants
(2 × 4)x^2xx^2y^3y^4z^2
Simplify 2 × 4 to 8
8x^2xx^2y^3y^4z^2
Use the Product Rule: x^ax^b = x^a + b
8x^2 + 1 + 2y^3 + 4z^2
Simplify 2 + 1 + 2 to 5
8x^5y^3 + 4z^2
Simplify 3 + 4 to 7
<u>8x^5y^7z^2</u>

When two countries are interdependent both countries can economically grow
Answer:
The value of g'(10)=
Step-by-step explanation:
Given function is f(x)=
Take f(x)=y
y=
Subtract 2 from both side.
y-2=
x=
The inverse of f(x) is written as
It is said as g is inverse of f
g(y)=\frac{4}{y-2}[/tex]
g(y)=
g(10)=
g(10)=
Differentiating both sides we get,
g'(y)=
g'(y)=
To find g'(10)=
g'(10)=
I’m pretty sure it’s B but if I’m wrong I’m so sorry
