Answer:
Maurice is correct.
Step-by-step explanation:
Because in order to multiply correctly you must find the total number of turbines that has been built.
3x² - 2x + 7 = 0.
Using method of completing the square.
3x² - 2x = 0 - 7
3x² - 2x = -7 Divide through by 3.
x² - 2/3x = -7/3 ...........(d)
Coefficient of x = -2/3, half of it = 1/2*-2/3 = -1/3 square of it = (-1/3)² = 1/9
We add (1/9) to both sides of equation (d)
<span>x² - 2/3x = -7/3
</span>
<span>x² - 2/3x + 1/9 = -7/3 + 1/9
We factorize it by making using of half of the coefficient, -1/3
</span>
(x - 1/3)² = -7/3 + 1/9
<span>(x - 1/3)² = -20/9
</span>
That's the answer as asked by the question. -20/9
1) First, solve one linear equation for y in terms of x .
2) Then substitute that expression for y in the other linear equation.
3)Solve this, and you have the x -coordinate of the intersection.
4)Then plug in x to either equation to find the corresponding y -coordinate.
Answer:
Ad 1: 9.25/hr Ad 2: 8.25/hr
Step-by-step explanation:
1. Find how many hours you work:
- 40*50 = 2000 hours worked
2. Divide the pay by the hour to find the cost:
- 18500 / 2000 = $9.25
- 16500 / 2000 = $8.25
3. That is the answer :)
5 19 6 -18
-3
-15 -12 18
5 4 -6 0
Therefore, the width is 5x^2 + 4x - 6
