This is a simultaneous equation
Rearrange the second to give
x - y = 1
Add the two equations
(x + y) + (x - y) = 5 + 1
2x = 6
x=3
Substitute 3 into either equation
3 - 1 = y
y = 2
Answer:
-7/3
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
y = -7/3x + 5
<u>Step 2: Break Function</u>
<em>Identify Parts</em>
Slope <em>m</em> = -7/3
y-intercept <em>b</em> = 5
5 times 5 times 5 is 125.
1 times 1 times 1 is 1.
So you can fit 125 books into the box.
Answer:
11x²y³ - 4xy²
Step-by-step explanation:
remove the parenthesis and collect like terms
4x²y³ + 2xy² - 2y + 7x²y³ - 6xy² + 2y
= (4x²y³ + 7x²y³) + (2xy² - 6xy²) + (- 2y + 2y)
= 11x²y³ - 4xy² + 0
= 11x²y³ - 4xy²
