Answer:
see explanation
Step-by-step explanation:
Choose any value for x, substitute into the equation and solve for y, that is
x = - 1
2(- 1) + y = 8
- 2 + y = 8 ( add 2 to both sides )
y = 10
---------
x = 0
2(0) + y = 8
0 + y = 8
y = 8
----------------
x = 1
2(1) + y = 8
2 + y = 8 ( subtract 2 from both sides )
y = 6
---------------
x = 3
2(3) + y = 8
6 + y = 8 ( subtract 6 from both sides )
y = 2
----------------
4 possible solutions are (- 1, 10 ), (0, 8 ), (1, 6 ) and (3, 2 )
Answer:
Sale price is $2.58.
Paid with tax is $2.73
Step-by-step explanation:
If the make-up is originally $4.30 and you receive a 40% discount. This means you'll pay 60% of the price since 100-40=60.
To find this price, 60% as 0.6 is multplied with the price. 0.6*4.30 = $2.58
This is the sale price.
When you pay you will pay 6% tax or 0.06 of the price. Find this by multiplying $2.58 by 1.06.
2.58(1.06) = $2.73
t/5 = 2.9
For the first step, I would multiply both sides by 5, to get rid of the fraction.
That will leave
t = 14.5
So with what you have on your screen, I would drag “x” and “5” to both sides of the equation.
