The scale factor that Ivory used to create their scaled copy is;
<u><em>Scale is 1 interval on graph represents 4 units of the rectangle. This is 1:4 ratio.</em></u>
- From the given image, we can see that the y-axis of the rectangle has 3 intervals while the x-axis has 1 intervals
- Now, from the image, we are told that the area of the scaled copy is 48 square units.
What this means is that the area of the triangle she is trying to represent with that graph is 48 square units.
- Now, if one interval of the graph is x-units, then it means;
length; y-axis = 3x units
width; x-axis = x units
- Area of a rectangle is given by;
Area = Length × width
Thus;
3x * x = 48
3x² = 48
x² = 48/3
x² = 16
x = √16
x = 4
<em>Thus, 1 interval on the graph represents 4 units of the rectangle.</em>

Answer:
192x-4= -768
Step-by-step explanation:
Using compound interest, it is found that Dante was 6.6 years old when the balance in the account reached $13,000.
<h3>What is compound interest?</h3>
The amount of money earned, in compound interest, after t years, is given by:
In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
In this problem, we have that the parameters are given as follows:
A(t) = 13000, A(0) = 10000, r = 0.04, n = 12.
Hence the time in years is found as follows:
t = 6.6

5/2=2.5 per....
that is how fast its going. Don't forget units for it to make sense
Answer:
1st,2nd, and 4th
Step-by-step explanation:
1)
2x + 14 = 28➡ x = 7
2)
60 = 4x + 32 ➡ x = 7
3)
2x - 6 -12 = -2x - 20 ➡ 4x = -2x = -1/2
4)
3x - 15 = 1 + 5x - 30 ➡14 = 2x ➡ x = 7
