Answer:
y = -x + 3; could also be y + 1 = -(x - 4) or y = -(x - 4) - 1 or x + y = 3
Step-by-step explanation:
No options given, so I hope this helps.
1. Identify any of the equations that have the same slope as your given equation (-1). If there's only one, stop here.
2. Find the y-intercept by replacing (x,y)=(4,-1) in the equation y = -x + b and solve for b: -1 = -(4) + b ==> 3 = b
3. Replace b in the equation y = -x + b with 3.
Yes,
(0,3) = (x,y)
0 = x
3 = y
Y = x + 3
Turns into:
3 = 0 + 3
0 + 3 = 3
Hope this helps you understand! <3
Answer:
1. Yes
2. No
3. Yes
4. No
Step-by-step explanation:
When you say a random sample, this means that every member of the population will have a chance to be part of the sample. If you consider the scenarios, only the 1st and 3rd option will come up with a random sample because the respondents of the sample is not predetermined. If you take the other options into consideration, you can see that not everyone would have had a chance to be part of the sample.
Answer:
Negative
Step-by-step explanation:
A negative plus a negative (negative minus a positive) will give you a negative. -1.69 + (-1.69) = -3.38
-3.38 is a negative, therefore the answer is negative.
