Answer:
If you look at the slope-intercept form equation: y = mx + b
y is the output, m is the slope, and b is the y-intercept. To find the slope, you need to look at mx for your equation.
Since it is you need to look at the number before the x, which in this case will be -7/3
So your slope will be m = -7/3
Answer:
See the explanations below
Step-by-step explanation:
Given the function y = x²+12x
We are to find the inverse and identify the error in the calculation:
Step 1: Replace y with x
x = y²+12y
First Error: There is an error here y, the variable attached to x should be y and not x that is y = y²+12y and not y = y²+12x. The x should be totally replaced with
The second error is where he wrote y = √-11x
The square root of a value must return both negative and positive value not only the positive value. Hence the correct expression should have been y = ±√-11x (Note that the sign ± was introduced)
Third error: Since the value inside the square rot is a negative value hence the value of x must be negative i.e x must be less than zero not greater then. The correct inequality expression should have been <u>x <0</u> and not
x< 0
