Answer:
B
Step-by-step explanation:
To have infinitely many solutions, the lines must be identical consisting of exactly the same points to make it. This means when in simplest form their equations are the same as well.
Simplify 2x+2y=8 by dividing by 2 throughout the entire equation. It becomes x+y = 4. This equation matches B.
Answer:
489.6
Step-by-step explanation:
6 x 6 x 2 x 4 x 1.7
6 x 6 = 36
36 x 2 x 4 x 1.7
36 x 2 = 72
72 x 4 x 1.7
72 x 4 = 288
288 x 1.7 = 489.6

Coefficient is usually the whole number in the beginning. I believe 5-7 are correct. I'm a little iffy about 8. Good luck!
Answer:
a) -45, <u>-43.5, -42, -40.5</u>, -39. f(n) = -45 + 1.5(n-1)
b) -34, 3, 40, 77. f(n) = -34 + 37(n-1)
Step-by-step explanation:
The explicit formula for an arithmetic formula can be defined as: f(n) = f(1) + d(n-1).
Where n is the number, and d is the common difference.
