Answer:
y = -3x + 7.
Step-by-step explanation:
First find the slope of the given line by converting to intercept form:
3x + y + 2 = 0
y = -3x - 2
So the slope is -3.
Then the line we want has a slope of -3 also (as it is parallel).
y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line:
m = -3, x1 = 1 and y1 = 4, so we have:
y - 4 = -3(x - 1)
y = -3x + 3 + 4
y = -3x + 7.

❖ To find the mean, add up all the numbers and divide by the amount of numbers there are. To find the range, subtract the highest number by the lowest number in the data set.
2. Mean = 35 Range = 78
3. Mean = 43 Range = 58
4. Mean = 63 Range = 73
5. Mean = 61 Range = 56
6. Mean = 55 Range = 83
7. Mean = 61 Range = 53
8. Mean = 60 Range = 75
9. Mean = 50 Range = 76
10. Mean = 50 Range = 81

Answer:
The formula is 10 - 3n
Step-by-step explanation:
For an nth term in an arithmetic sequence
U( n ) = a + ( n - 1)d
Where n is the number of terms
a is the first term
d is the common difference
From the sequence above
a = 7
d = 4 - 7 = - 3
The formula for an nth term is
U(n) = 7 + (n - 1)-3
= 7 - 3n + 3
The final answer is
= 10 - 3n
Hope this helps you.
Answer:
Yes.
Step-by-step explanation:
Yes, it is possible. For example, 0.2 and 0.2 both have one decimal place and one significant digit. Their product, 0.04, has one significant digit, but has 2 decimal places.
