P = P₀ (1 + r)ⁿ

= 1.17(1 + 0.09)⁵

= 1.17(1.09)⁵

= 1.17(1.5386)

= 1.80

Answer: $1.80

Note: If you don't know the formula, you could calculate each year.

Year 0: $1.17

Year 1: $1.17 + $1.17(0.09) = $1.2753

Year 2: $1.28 + $1.28(0.09) = $1.3948

Year 3: $1.39 + $1.39(0.09) = $1.5155

Year 4: $1.51 + $1.51(0.09) = $1.6464

Year 5: $1.65 + $1.65(0.09) = $1.7982 <em>which rounds up to $1.80</em>

Solve the system using substitution. Check your solution.<br> 2x - y= 65<br> 5y = x

lyudmila [28]

Answer:

The solutions to the system of equations are:

$x=\frac{325}{9},\:y=\frac{65}{9}$

Step-by-step explanation:

Given the system of the equations

$\begin{bmatrix}2x-y=65\\ 5y=x\end{bmatrix}$

isolate 'x' for 2x-y

$2x-y=65$

Add y to both sides

$2x-y+y=65+y$

$2x=65+y$

Divide both sides by 2

$\frac{2x}{2}=\frac{65}{2}+\frac{y}{2}$

$x=\frac{65+y}{2}$

$\mathrm{Subsititute\:}x=\frac{65+y}{2}$

isolate 'y' for $5y=\frac{65+y}{2}$

$5y=\frac{65+y}{2}$

$10y=65+y$

subtract y from both sides

$10y-y=65+y-y$

$9y=65$

Divide both sides by 9

$\frac{9y}{9}=\frac{65}{9}$

$y=\frac{65}{9}$

$\mathrm{For\:}x=\frac{65+y}{2}$

$\mathrm{Subsititute\:}y=\frac{65}{9}$

$x=\frac{65+\frac{65}{9}}{2}$

$x=\frac{325}{9}$

The solutions to the system of equations are:

$x=\frac{325}{9},\:y=\frac{65}{9}$

Please solve both, graph and show work. answer also has to be in y=mx+b format.

alexandr1967 [171]

2x-y=1
-2x -2x
-----------------
-y=-2x+1
Multiply by -1
y=2x-1

x+y=2
-x -x
------------
y= -x+2

What is the value of x

pashok25 [27]

Answer:

-10

Step-by-step explanation:

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result. Therefore, the value of x is -10.
