Remark
The first thing you should do is get a graph for this, so you can actually see what is going on. Then solve for slope y intercept. I put the graph into Desmos without a solution expression for y.
Graph Solution
The graph 3x - y + 1 = 0 shows you were the y intercept is. You can use this graph to draw your own along with a table.
Find slope y intercept form
3x - y + 1 = 0 Add y to both sides.
3x - y + y + 1 = y
y = 3x + 1
Answer
m is always the number in front of x when written in the slope intercept form.
Given that the <em>length</em> ratio between the radii of the two circles is (2 · x) / (5 · y). The ratio of the areas of the two circles is (4 · x²) / (25 · y²).
<h3>What is the area ratio of two circles?</h3>
According to the statement we know that the radius ratio between two circles. Given that the area of the circle is directly proportional to the square of its radius, then the <em>area</em> ratio is shown below:
A ∝ r²
A = k · r²
A' · r² = A · r'²
A' / A = r'² / r²
A' / A = (r' / r)²
A' / A = [(2 · x) / (5 · y)]²
A' / A = (4 · x²) / (25 · y²)
Given that the <em>length</em> ratio between the radii of the two circles is (2 · x) / (5 · y). The ratio of the areas of the two circles is (4 · x²) / (25 · y²).

Answer:
$1.62
Step-by-step explanation:
1. To find how much Erin spent, we have to multiply 0.54 by 3.
Therefore, Erin spent $1.62.
Answer:
24
Step-by-step explanation:
Answer:
100
Step-by-step explanation:
Multiply 40 by 3 because 40 is 1/3 and find the answer for 3/3.
I got 120, subtract 20 from 120 beacause there is 20 silver cards. The answer is 100
