halfway through the fourth year , harrys collection contains 400 pennies. study the graph provided at the beginning of this acti
elixir [45]

Answer:

The coordinates of the point is (3,5 , 400)

Step-by-step explanation:

The question is incomplete as the graph is not given in the question. Lets complete the question first. I have attached the graph related to this question below.

We can see in the graph that x-axis represents the years while the y-axis represents the pennies collected by Harry.

We have to find the coordinates of the point where he is able to collect 400 pennies.

As y-axis represents pennies, and the point to be found is at 400 pennies, so the y-coordinates of the point is 400.

Harry collects 400 pennies when he is halfway through 4rth year, which means that he has been collecting for:

3 years + Half of 4rth year = 3.5 years.

As x-axis represents the year and the point to be found is at 3.5 years, so the x-coordinate of the point is 3.5.

So, the coordinates of the point is (3,5 , 400)

This point can be seen in the second graph

2(x-1)+8=4x-20 find the solution<br> (15 points)
Alenkasestr [34]

Answer:

13

Step-by-step explanation:

2(x-1)+8=4x-20

distribute 2

2x-2+8=4x-20

2x+6=4x-20

subtract 2x from both sides

6=2x-20

add 20 to both sides

26=2x

divide both sides by 2

x=13

After a 30% discount, an item was sold for $15,750. What was the original price of the item?
serious [3.7K]

Answer:

Step-by-step explanation:

Hi there,

To get started, set up a relationship:

x⇒$15,750  

We know some original price was <em>reduced</em> to 15,750. The discount is 30%, and discounts are done by taking that % of the original price <em>off</em>, or <em>subtracted. </em>So, you are taking a price and subtracting a certain percentage off:

x-0.3x=0.7x    30% is same as 0.3. In other words, the discounted price is 70% of the original value.

Now, let's set up an equation:

0.7x=15,750    Divide both sides by 0.7 to isolate x:

x=\frac{15750}{0.7} =22,500  The original price was $22,500.
