Step-by-step explanation:
Jeff received 280$ from his mother
Such questions are the simplest as it needs you to just write the conditions accordingly which then simplifies and provides you the answer.
This question can be solved using two tricks which are shown below:-
Trick 1 :
1 – 1/4 = 3/4 (used for the 1st 7 days)
1/4 – 410 (used for 8th and 9th days)
(3/4)/7 ——- (1/4 – 10)/2
(3/4) x (2/7) = 3/14 ——- (1/4 – 10)
1/4 – 3/14 = (7 – 6)/28 = 1/28 ——- 10
28/28 ——- 10 x 28 =$ 280
Trick 2 :
7 days ——- 3/4
1 day ——- 3/28
2 days ——- 6/28
6/28 ——- (1/4 – 10) = 7/28 – 410
1/28 ——- 10
28/28 ——- 10 x 28 = $280
Thus Jeff received 280$ from his mother.

Answer:
y = 4x + 12
Step-by-step explanation:
The slope of the line y = 4x - 9 is 4.
The slope of the line we are looking for is also 4.
y - y1 = m(x - x1)
y - 4 = 4[x - (-2)]
y - 4 = 4(x + 2)
y - 4 = 4x + 8
y = 4x + 12
Answer: y = 4x + 12
