Answer:
B.
Step-by-step explanation:
9 is the first term then we keep adding common difference d = 7 to get the rest of the terms.
9, 9 + 7, 9 + 7 + 7, and so on.
= 9, 16, 23, 30, 37......
Na20+H20 -> 2NaOH
40.75
3/4 = 0.75
40 + 0.75= 40.75
y = -x + 4
y + 2 = -x - 1
y = - x - 1 - 2
y = -x - 3
Point: (-2,6)
Slope -1
y-intercept: 6 - (-1)(-2)
= 6- 2 = 4
