100% - 80% = 20%
20% = 0.2
150 * 0.2 = 30
answer: 30 students chose math
Step-by-step explanation:
- 3 ( x + 2 ) + 9 + 7x = 4x + 5 - 2
- 3x - 6 + 9 + 7x = 4x + 5 - 2
- 3x + 7x + 9 - 6 = 4x + 5 - 2
4x + 3 = 4x + 3
Yes the equation is linear because the linear equation is y=mx+b and y=85x-600 is linear.
In order to divide a fraction by a whole number, you must make the whole number a fraction, by putting the number over one. In order to divide something by a fraction, you flip the divisor (3 or 3/1) to get the reciprocal (1/3) and multiply the two fractions together. Hope this helps! <span />
The average rate of change from x = -9 to x = -1 of the graph of the given function is 0.
We know that the rate of change of a function is nothing but the slope of the line.
The slope of the line is given by;
Slope = Change in y-coordinate / change in x-coordinate
We are given the graph of a function.
We need to find the average rate of change from x = -9 to x = -1.
Let us find the value of y or f(x) for the given value of x.
For x = -9, y = 2
For x = -1, y = 2.
Put the values of x and y in the slope formula, we will get;
Slope = (2 - 2) / (- 1 - (-9)) = 0
So, the rate of change of function is 0.
Thus, the average rate of change from x = -9 to x = -1 of the graph of the given function is 0.
