Step-by-step explanation:
Basically each side of the triangle represents a square on each which then makes the hypotenuse the largest square. Now, the area of a square is formulated by (1 side)² . Pythagorean theorem says that the area of the largest square is the sum of the 2 smaller square which is why the formula is a² + b² = c².
Answer: y=1/2x
Step-by-step explanation:
The equation we can use is slope-intercept form. The formula is y=mx+b. The m represents the slope, and b is the y-intercept. The line passes through the y-axis at (0,0). therefore, the y-intercept is 0.
To find the slope, we can take any two points and use the formula to solve for slope. Let's use (2,1) and (4,2).
The slope is 1/2. Our equation is y=1/2x+0 or y=1/2x.

Answer:
Step-by-step explanation:
Alberto uses the steps below to solve the equation One-half x minus 3 equals 7. Step 1: One-half x minus 3 plus 3 equals 7 plus 3 Step 2: One-half x plus 0 equals 10 Step 3: One-half x equals 0 Step 4: 2 (one-half) x equals 2 (10) Step 5: 1 x equals 20 Step 6: x equals 20.
Which justifies Step 6 of his work? the addition property of equality the identity property of addition the multiplication property of equality the identity property of multiplication.
1/2x - 3 = 7
One-half x minus 3 equals 7.
Step 1: add 3 to both sides
1/2x - 3 + 3 = 7 + 3
One-half x minus 3 plus 3 equals 7 plus 3
Step 2:
1/2x + 0 = 10
One-half x plus 0 equals 10
Step 3: One-half x equals 10
1/2x = 10
Step 4: Multiply both sides by 2
1/2x * 2 = 10 * 2
2 (one-half) x equals 2 (10)
Step 5:
1x = 20
1 x equals 20
Step 6:
x = 20
x equals 20.
identity property of multiplication states that when 1 is multiplied to an equation, the result remains the same.
identity property of multiplication justifies Step 6 of his work
