A student says that the graph of the equation y=3(x+8) is the same as the graph of y=3x, only translated upwards by 8 units. do you agree? why or why not??

Answers

Answer:

agree

Step-by-step explanation:

because they have the same slope of 3. so they are parallel with different y intercepts

Answer:

You don't agree because the equation is y = 3x and f(x) = 3x

Step-by-step explanation:

You would not agree because y = 3x would essentially be a line starting at 0 and going up by 3 whereas

Y = 3(x+8) the graph would start at (0, 24) first point and the second would be (-8,24)

1. 30 inches to 24 inches

2. $126 to $150

Answers

1. 20% decrease

2. 16% increase

Explaination:

Question 1.

30 inches to 24 inches is a decrease, because 24 is smaller than 30.

(30-24)/30 * 100%

= 6/30 * 100%

= 20%

Ans: 20% decrease

Question 2.

$126 to $150 is an increase, because 150 is larger than 126.

(150-126)/150 * 100%

= 24/150 * 100%

= 4/25 * 100%

= 16%

Ans: 16% increase
