Answer:
a = -6
Step-by-step explanation:
The given line in point-slope form is y + 2 = (1/2)(x - 4).
Replacing x with -4 yields y + 2 = (1/2)(-4 - 4) = (1/2)(-8)
Then y + 2 = -4, and so y = -6, or a = - 6.
According to time, texting speed is a two-variable type of data that's represented by a scatterplot. This is because a scatterplot helps graph the data points, so that you can figure out and interpret the relationship.
The other answer is the sample response, so it's better to put it in your own words. :)
To find the x intercept of the function, we would find g(x) = 0
To do this, we would set each expression in the piecewise function to zero and solve for x. We have
For
x/3 + 2 = 0
let us multiply both sides of the equation by 3. We have
x/3 * 3 + 2 * 3 = 0 * 3
x + 6 = 0
x = - 6
- 6 is less than - 1
- 6 < - 1
It satisfies the inequality. Thus, x = - 6 is in the domain
For
4x - 2 = 0
adding 2 to both sides of the equation, we have
4x - 2 + 2 = 0 + 2
4x = 2
Dividing both sides of the equation by 4, we have
4x/4 = 2/4
x = 1/2
x = 1/2 is less than 1. It is not in the domain of this equation. Thus, there is no x interscept at x = 1/2
Therefore, the x intercept of the piecewise function is (- 6, 0)
