Write the equation for an exponential function that triples ever year, x, when the original amount is 4.

Answers

Answer:

y = 4(3)^x

Step-by-step explanation:

Here, we want to write the exponential equation

From the question, we have the equation tripling in x value every year and the original amount is 4

The exponential equation is of the form;

y = a(b)^n

In this case;

a = 4 , b = 3 and n = x

So we have the equation as;

y = 4(3)^x

a line is perpendicular to y=-2x+5 and intersects the point (-4,2). what is the equation of this perpendicular line?

Answers

Answer:

y = 1/2x + 4

Step-by-step explanation:

If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.

So solve for b: using y = mx + b

2 = 1/2(-4) + b

2 = -2 + b

4 = b

Put it all together

y = 1/2x + 4

Mrs. Zahid bought 6 bouquets at $ m each, and 8 packs of chocolates at $ ‘n’ each. She had $(2m + 5n) left. Find the amount of money she had at first.

Answers

Answer:

$(8m + 13n)

Step-by-step explanation:

Given that :

Total Cost of 6 bouquet = 6m

Total cost of 8 chocolate = 8n

Total amount spent = $(6m + 8n)

Total amount left = $(2m + 5n)

Hence, amount had at first :

Total amount. Spent + total amount. Left

(6m + 8n) + (2m + 5n)

(6m + 2m + 8n + 5n)

$(8m + 13n)

Danny has at least $15 more than his big brother. Danny's brother has 72. How much money does Danny have?

Answers

Answer:

d >= $87

Step-by-step explanation:

Since we are not given the exact difference between the amount of money that Danny has in comparison to his brother, then this would ultimately be an inequality question. We are told that Danny has atleast $15 more than his brother, meaning that the minimum that Danny can have is $15 more than his brother. Danny's brother has $72 so we need to add these two values together.

$72 + $15 = $87

Therefore Danny would have a minimum of $87 but at the same time can have more than that. Therefore, we can use the following inequality to represent Danny's money (d)

d >= $87

Write an equation of the line that passes through (1,2) and is parallel to the line y = -5x+4

Answers

Answer:

y =-5x + 7

Step-by-step explanation:

y = -5x + 4

Slope = -5

Parallel lines have same slope

Slope of the parallel line to this line = -5

(1 , 2)

y -y1 =m(x - x1)

y - 2 = -5(x - 1)

y -2 = -5x + 5

   y = -5x + 5 + 2

  y = -5x + 7

I can’t really help you too much with the graphing but what you do with ordered pairs is whatever is the first number (example for point A it’s -2) you go and find it on the horizontal line. Once you find it on the horizontal line you either go up or down the graph by how many units the second number is (4 so you would go up four in the graph) and then you plot the point
here you go, just put dot on it

$73 is what percent of $125

Answers

Answer: The question $73 out of 125 is 58.40%

Step-by-step explanation:

$73 out of 125 is what percent Answer: The question $73 out of 125 is 58.40%, which is the same as 73/125 as a percent. This can be solved using this calculator above

The $73 is approximately 58.4% of $125.

To find what percent $73 is of $125, we can use the following formula:

Percent = (Part / Whole) * 100

In this case, $73 is the part and $125 is the whole.

Substituting these values into the formula:

Percent = (73 / 125) * 100

Dividing 73 by 125:

Percent = 0.584 * 100

Multiplying 0.584 by 100:

Percent = 58.4

Therefore, $73 is approximately 58.4% of $125.
