Answer:
Step-by-step explanation:
8z, 12y, 7.7 are separate terms
z and y are variables
8 and 12 are coefficients
7.7 is the constant
If a data set contains three points, and two of the residuals are -10 and 20, the third residual is 10 (option B).
<h3>What is a residual?</h3>
A residual is the difference between the observed value and the estimated value of the quantity of interest.
The residual of a data points should normally sum up to zero (0). This means the following applies:
-10 + 20 + x = 0
x = 10
Therefore, if data set contains three points, and two of the residuals are -10 and 20, the third residual is 10.

Answer:I’m pretty sure it would be A!
Step-by-step explanation:
Answer:
Not perpendicular
Step-by-step explanation:
Convert it to y-intercept form first:
5x - 4y = -1
-4y = -5x - 1
y = 5/4x + 1/4
4x - y = -9
-y = -4x - 9
y = 4x + 9
y = 5/4x + 1/4
y = 4x + 9
From the slopes, they are not considered perpendicular because one of the line slope is not a <em>negative reciprocal</em> of the other line slope.
