Answer:
The solution to the system of equations is:

Step-by-step explanation:
Given the system of equations

Multiply -x+8y=22 by 5: -5x+40y=110

so adding the equations




solve 36y = 144 for y:

divide both sides by 36

Simplify

For 5x-4y=34 plug in y=4


Add 16 to both sides

Simplify

Divide both sides by 5

Simplify

Therefore, the solution to the system of equations is:

Answer:
First consider the original amount.
Then consider the rate of tax or markup
To find the tax or markup, multiply the rate by the original amount.
To find the total cost, add the tax or markup to the original amount.
Step-by-step explanation:
Example
A phone has a listed price of $790 before tax. If the sales tax rate is 6.5% find the total cost of the phone with sales tax included. Round your answer to the nearest cent as required.
Solution
Step 1:
List price of the phone = $790
Sales tax rate = 6.5%
Step 2:
Sales tax = 6.5% of 790=0.065×790=51.35
Step 3:
Total cost of phone including sale tax = list price + sales tax
= 790+51.35
= $841.35

Answer:

Step-by-step explanation:
we are given
center =(0,0)
we can compare with
center=(h,k)=(0,0)
so, h=0 and k=0
a=2 and b=5
now, we can use equation of hyperbola formula

now, we can plug values

we can simplify it
and we get equation of hyperbola as
