The answer is: [A]: "No solution" .
_______________________________________________
Note: Given:
_______________________________________________
y = 4x + 8 ;
y = 4x + 2 ;
_______________________________________________
Since: "y = y" ;
4x + 8 = 4x + 2 ; which is not true;
______________________________
4x + 8 ≠ 4x + 2 ; since, "8 ≠ 2" ;
Note: Suppose: "4x + 8 = 4x + 2" ;
→ Subtract "4x" from each side of the equation:
4x + 8 − 4x = 4x + 2 − 4x ;
to get:
_________________
" 8 = 2 " ; not true ; since "8 ≠ 2" ;
______________________________
Also, suppose:
_______________________________
4x + 8 = 4x + 2 ;
→ Subtract "2" from BOTH SIDES of the equation;
4x + 8 − 2 = 4x + 2 − 2 ;
to get:
4x + 6 = 4x
(Note: "4x + 0 = 4x" ; but "4x + 6 ≠ 4x") l
But even if we have:
4x + 6 = 4x ;
→ Subtract "4x" from EACH side of the equation:
4x + 6 − 4x = 4x − 4x ;
to get:
6 = 0 ; which is not true; "6 ≠ 0" .

Answer:
B
Step-by-step explanation:
Plug in all the values for x & y into the equation y=2x+3 (B). 2*2=4. 4+3=7. All the other values for x & y match up perfectly as well. The answer is B
Answer
39.81
Step-by-step explanation:
First I converted the percent to a decimal which was 0.15
Then I multiplied 0.15 by 34.62 which was 5.193
Lastly I added 5.193 by 34.62 which was 39.813
I rounded it to 39.81
<u><em>Answer 39.81 </em></u>
Answer:
=3√5
Step-by-step explanation:
Simplifying this expression involves prime factorisation of
45
45 = 3⋅3⋅5
(3 and 5 are the prime factors of 45)
So √45
=√3⋅3⋅5
=√32⋅5
=3⋅√5
=3√5
Mean=10.5
median=10
that is the answer
