Answer:

y=4x+5

Step-by-step explanation:

Slope intercept is y=mx+b. y=y-value, m=slope, x=x-value and, b=y-intercept.

With the information given we can plug some numbers into the equation: 1=4(-1)+b

Solving for b we get, {4(-1)=-4, -4--4=0, 1--4=5} 5=b. Therefore, B is equal to 5.

Plug that into the original problem: y=4x+5 and re-add the plot point 1=4(-1)+5 and solve to verify the answer.

After solving, {4(-1)=-4+5=1} we get  1=1 which is a true statement.

skelet666 [1.2K]

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.
