Answer:
(6, - 1 )
Step-by-step explanation:
Given the 2 equations
x + 7y = - 1 → (1)
- 4x - 2y = - 22 → (2)
Rearrange (1) expressing x in terms of y by subtracting 7y from both sides
x = - 1 - 7y → (3)
Substitute x = - 1 - 7y into (2)
- 4(- 1 - 7y) - 2y = - 22 ← distribute and simplify left side
4 + 28y - 2y = - 22
4 + 26y = - 22 ( subtract 4 from both sides )
26y = - 26 ( divide both sides by 26 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = - 1 - 7(- 1) = - 1 + 7 = 6
Solution is (6, - 1 )

Answer:
Step-by-step explanation:
<u>Given data:</u>
- <u>x | 2 | 3 | 4 | 5 | 6 </u>
- y | 21 | 69 | 261 | 1029 | 4101
<u>Logarithms of y-values:</u>
- log 21 = 1.322
- log 69 = 1.839
- log 261 = 2.417
- log 1029 = 3.012
- log 4101 = 3.613
<u>The ordered pairs:</u>
- (2, 1.322), (3, 1.839), (4, 2.417), (5,3.012), (6, 3.613)
<u>Using an online calculator found the equation of the regression line:</u>
<u>In our case it is:</u>
Let's represent that number as X:
6(9+2X) = 5X + 12
54 + 12X = 5X + 12
7X = -42
X = -6
