Answer: OPTION A
Step-by-step explanation:
The equation of the line in slope-intercept form is:

Where m is the slope and b the y-intercept.
Solve for y from each equation:

As you can see the slope and the y-intercept of each equation are equal, this means that both are the exact same line. Therefore, you can conclude that the system has infinitely many solutions.
Answer:
$21.57
Step-by-step explanation:
4.5 (1.22) + 0.8 (1.70) + 4.6 (3.20) =
5.49 + 1.36 + 14.72
21.57
2+1.25f=10-2.75f Add the variables
2+4f=10 isolate the variable
4f=8
f=2
Answer:
y=2/3x-8
Step-by-step explanation:
2x-3y=24
3y=2x-24
y=2/3x-24/3
y=2/3x-8
y=mx+b where m=slope and b=y-intercept.
Answer:
Step-by-step explanation:
<u>Item 1:</u>
Discount = Original price - discount price
= 22.50 - 13.50
= $ 9
Discount percentage = 
= 40%
Discount percentage = 40%
Tax = 14.31 - 13.50 = $0.81
Tax% =
= 6%
Tax percentage = 6%
<u>Item 2:</u>
Tax = 6% of 16.20
= 0.06 * 16.20
= 0.972
Tax = $ 0.97
Total price (including tax )= 16.20 + 0.97 = $ 17.17
x = $ 17.17
<u>Item 3:</u>
Discount = 40% of 32.50
= 0.4 * 32.50
= $ 13
y = 32.50 -13
y = $ 19. 50
Tax = 6% of 19.50
= 0.06 * 19.50
= 1.17
z = 1.17 + 19.50
Z =$ 20.67
