How to graph 6x + 3y = 12
explanation:
Step 1: Find x intercept: substitute 0 for y: solve for x
• 6x + 3(0) = 12
• 6x = 12
• x = 2
Step 2: Then Find y intercept: also substitute 0 for x; solve for y
• 6(0) + 3y = 12
• 3y = 12
• y = 4
So plot x and y intercepts: ( 2,0 ) and ( 0,4 ) then draw a line through the points.

How to graph 3x + y = 5
explanation:
Step 1: Find x intercept: substitute 0 for y: solve for x
• 3x + 5(0) = 15
• 3x = 15
• x = 5
Step 2: Then Find y intercept: also substitute 0 for x; solve for y
• 3(0) + 5y = 15
• 5y = 15
• y = 3
plot x and y intercepts: (5,0 ) and ( 0,3) then draw a line through the points.

Answer:
21, 42, 63, 84.
Step-by-step explanation:
The cards with a star and a circle must be multiples of 3 and 7.
So these must also be multiples of 21:
These are 21, 42, 63 and 84.

Step-by-step explanation:
<u>Step 1: Define</u>
(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)
<u>Step 2: Simplify</u>
- [Distributive Property] Distribute negative: 3x² + 2y² - 3x + 2x² + y² - 2x - x² - 3y² - x
- Combine like terms (x²): 4x² + 2y² - 3x + y² - 2x - 3y² - x
- Combine like terms (y²): 4x² - 3x - 2x - x
- Combine like terms (x): 4x² - 6x
