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
hope this helped!

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
