Answer:
15x-7
Step-by-step explanation:


Answer: x + (x + 1) + (x + 2) = -21
Step-by-step explanation:
The z-score is the number of standard deviations away from the mean that a data point is. To find the value of z for which 0.9426 of values are within z deviations of the mean, this means that (1 - 0.9426) = 0.0584 are beyond this interval, and this would be divided by 2: 0.0584 / 2 = 0.0292 of values are located below -z, while another 0.0292 is above +z.
Based on z-tables, this occurs at around z = 1.89, so the interval is from -1.89 to 1.89.

just wanted to let you know you didn't attach a picture would love to answer question in comments once I can see the photo
The slope of the tangent at a given point can be found by differentiating the given equation and substituting the value of x at the point as such:
y = 9 - x²
dy/dx = -2x; x = 1
dy/dx = -2
For a line with the slope of -2 and passing through point (1 , 12)
y -12 = -2(x - 1)
