Step-by-step explanation:
Answer 2
Answer:

Answer:(0,5)


Step-by-step explanation:

Y-3=2(x+1)


Rewrite it

2(x+1)=y-3

Sub. 0 for xto find y

2=y-3

Y-3=2

Y=2+3

Y=5


5-3=2(x+1)

2=2x+2

2x+2=2

2x=-2+2

2x= 0

X=0



To check

5-3=2(0+1)

2=2(1)

2= 2


It checks

Nicole used 3/8 of her ribbon to wrap a present if she used 6 feet of ribbon for the present how much ribbon did Nicole have at first

Answers

Nicole used only a fraction of her ribbon to wrap the present

the length of ribbon she used is 6 feeet

so lets name the length of the ribbon she had originally as X

the fraction of X she used was - 3/8 of X

so we can write the following equation

(3)/(8) of X = 6

when of function is used we multiply

(3)/(8)*X = 6

3X = 6*8

3X = 48

X = 16

therefore length of the original ribbon piece Nicole had was 16 feet
The answer is 16 feet

3/8 of her ribbon is 6 feet

3/8 * 8/3 = all of the ribbon Nicole had

6 * (8)/(3) = (48)/(3) = 16

The director of marketing at a large company wants to determine if the amount of money spent on internet marketing is a good predictor of company profit. She fits a least-squares regression line to 20 months of data and computes the following regression line:Profit = 372.6 + 17.2(advertising dollars)

What is the value of the residual for advertising dollars spent equal to $1,020 and Profit equal to $17,500? Round to the nearest integer.

Answers

Given:
Profit = 372.60 + 17.2(advertising dollars)
Advertising dollars = 1,020
profit = 17,500

17,500 + residual value = 372.60 + 17.2(1,020)
17,500 + residual value = 372.60 + 17,544
17,500 + residual value = 17,916.60
residual value = 17,916.60 - 17,500
residual value = 416.60

residual value is 416.60 or 417 rounded off to the nearest integer

A store is having a sale where movies or 15% off their original price a movie is on sale for $22.10. What was the original price

Joe leaves $3 as a tip for a meal that cost $22 . If a good tip is between 15% and @0% is this a good tip ?

Answers

Yes, a good tip would either be $3 or $4. To calculate the tip, you just take the overall total and multiply it by the percentage in decimal form.

Total = $22
15% = .15
20% = .20

(22) x (.15) = 3.3 = $3
(22) x (.20) = 4.4 = $4
