Answer:
C. 3+ (-4)
Step-by-step explanation:
First we have three but then we go back 4 spaces which results in -1
The simplified answer of C. would be 3-4= -1
Answer/Step-by-step explanation:
A. The cluster is where the 100 is to the 235. The outlier is 1,110 cause it is way out in the open alone almost 300 numbers away from its nearest number
B. For the correlation if you notice how it goes from 200... > 400...> 600...>800...it kinda like a pattern of adding 200
C. The independent variable is temperature and the dependent is sales. since the amount of money made depends on the temperature.

Step-by-step explanation:
Given the 2 equations
y = x² + 2x + 7 → (1)
y - 7 = x → (2)
Rearrange (2) expressing y in terms of x by adding 7 to both sides
y = x + 7 → (3)
Substitute y = x + 7 into (1)
x + 7 = x² + 2x + 7 ( subtract x + 7 from both sides )
0 = x² + x ← factor out x from each term
0 = x(x + 1)
Equate each factor to zero and solve for x
x = 0
x + 1 = 0 ⇒ x = - 1
Substitute these values into (3) for corresponding values of y
x = 0 → y = 0 + 7 = 7
x = - 1 → y = - 1 + 7 = 6
The solutions are
(- 1, 6 ) and (0, 7 )
