Answer:
x = √(-1) = i
Since the value of √(-1) is not real.
The system has no real solution.
Step-by-step explanation:
The solution to the system of equations is at the point where they intercept each other.
y1 = y2
For the given equation;
y=x^2-2x and y=-2x-1
To get the where they intercept, we will equal both equations;
y=x^2-2x = -2x-1
x^2 - 2x = -2x - 1
x^2 - 2x + 2x + 1 =0
x^2 +1 = 0
x^2 = -1
x = √(-1) = i
Since the value of √(-1) is not real.
The system has no real solution.
3 plus 1 equals 4 so its 4/6. When you simplify it the answer is 2/3
First, start off with the number of double basses. the question says there are 4. now, add up all of the numbers of instruments in order to find the total. 7+4+11+11+11=44 (three 11’s for the first violins, second violins and violas). now since you’re comparing the double basses to the total amount, the ratio is 4/44. You can also simplify this ratio by dividing both numbers by 4, which will become 1/11. Now, in order to find the decimal, just divide the fraction. 1/11=.09 repeating. Hope this helped!
the simplification performed in step 2 is invalid or incorrect
