Answer:
![\boxed{ \bold{ \huge{ \boxed{ \sf{8 + 8i}}}}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cbold%7B%20%20%5Chuge%7B%20%5Cboxed%7B%20%5Csf%7B8%20%2B%208i%7D%7D%7D%7D%7D)
Option D is the correct option.
Step-by-step explanation:
![\sf{(3 + i) + (5 + 7i)}](https://tex.z-dn.net/?f=%20%5Csf%7B%283%20%2B%20i%29%20%2B%20%285%20%2B%207i%29%7D)
When there is a ( + ) in front of an expression in parentheses , there is no need to change the sign.
That means, the expression remains the same.
Just remove the unnecessary parentheses
⇒![\sf{3 + i + 5 + 7i}](https://tex.z-dn.net/?f=%20%5Csf%7B3%20%2B%20i%20%2B%205%20%2B%207i%7D)
Collect like terms and simplify
⇒![\sf{3 + 5 + i + 7i}](https://tex.z-dn.net/?f=%20%5Csf%7B3%20%2B%205%20%2B%20i%20%2B%207i%7D)
⇒![\sf{8 + 8i}](https://tex.z-dn.net/?f=%20%5Csf%7B8%20%2B%208i%7D)
Hope I helped!
Best regards!!
Answer: 1 .Thus for a graph to have an Euler circuit, all vertices must have even degree. The converse is also true: if all the vertices of a graph have even degree, then the graph has an Euler circuit, and if there are exactly two vertices with odd degree, the graph has an Euler path.
2. A graph has an Euler circuit if and only if the degree of every vertex is even. A graph has an Euler path if and only if there are at most two vertices with odd degree.

Answer:
b = y intercept
Step-by-step explanation:
y = mx +b
This is the slope intercept form of a line
The m is the slope and the b is the y intercept
Answer:
.25
Step-by-step explanation:
The predicted value of y when x =7 is -8.5
<h3>How to predict the y value?</h3>
Start by drawing the line of best fit through the points
See attachment for the graph.
From the attached graph, we have the following value
y = -8.5 when x = 7
Hence, the predicted value of y when x =7 is -8.5
