What you want to do for each of those is follow the formula, y-y[1]=m(x-x[1]). When I say y[1] and x[1], I mean the x and y values given. So the first one would be y-4=-3(x-(-1)). Then you solve for y by distributing the -3 to x and +1 (+1 because two negatives make a positive), making the equation
y-4=-3x-3. Then you subtract the 4. Answer #1. y=-3x-7.
#2.
y-1=1(x-4)
y-1=x-4
y=x-5
#3.
y-2=2(x-(-1))
y-2=2x+2
y=2x+4
Hope this helped you!
The zeros of this functions are -4, 2, -4, and -4.
-4 is a multiple zero and has multiplicity 3.
2 is a zero. I would call it a simple zero, since it's only a zero once (AKA has multiplicity of 1).
Is this a "pick one answer" or "pick all correct answers"?
Answer:
Step-by-step explanation:
p+1 +8 = 8p+16
p+9 = 8p+16
9-16 = 8p-p
-7=7p
-7/7 =p
-1=p
Answer: The predictor variable in this problem is the amount spent on promotional material.
Explanation:
A predictor variable refers to variable needed to make a prediction of another variable. If we analyze the problem, we notice that the supermarket chain is predicting the sales revenue generated because once the supermarket spends on promotional material, it will result to sales revenue. Thus, the predictor variable is the amount spent on promotional material.
