Answer:
300=10x+20y
Step-by-step explanation:
You are trying to get the sales to equal 300 so the 10x and 20y added together will get you 300
Answer:
h = 6
Step-by-step explanation:
Given the 2 equations
- 3x + 4y = - 30 → (1)
9x + 5y = 39 → (2)
We require the value of the x- coordinate at the point of intersection, thus require to eliminate the y- term from the equations
Multiply (1) by 5 and (2) by - 4
- 15x + 20y = - 150 → (3)
- 36x - 20y = - 156 → (4)
Add (3) and (4) term by term thus eliminating y
- 51x = - 306 ( divide both sides by - 51 )
x = h = 6

Step-by-step explanation:
<u>Step 1: Define</u>
(3x² - 3x + 6) - (5x² + 2x + 9)
<u>Step 2: Simplify</u>
- [Distributive Property] Distribute negative: 3x² - 3x + 6 - 5x² - 2x - 9
- [Subtraction] Combine like terms (x²): -2x² - 3x + 6 - 2x - 9
- [Subtraction] Combine like terms (x): -2x² - 5x + 6 - 9
- [Subtraction] Combine like terms (Z): -2x² - 5x - 3
Answer:
x = -3.05
Step-by-step explanation:
x + 20x + 100 = 36
Combine like terms.
21x + 100 = 36
Subtract 100 on both sides.
21x = -64
Divide both sides by 21.
x = -3.04761904762...
