Answer:
y = - 5x
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 10 when x = 2, thus
k = = = - 5
y = - 5x ← equation of variation
Answer:
See the attached graphic
Step-by-step explanation:
1. Defense cards could be identify with <em>x</em> and offense cards with y.
2. Find the proportion:
<em>For every 4 defense cards (y), he owns 2 offense cards (x)</em>
<em>Offense cards (x) Defense cards (y)</em>
<em> 2 4</em>
<em> 3 6</em>
<em> 4 8</em>
If Chad has 4 offense cards, then he owns 8 Defense cards. Note that the proportional relationship between defense cards and offense cards is 2:1. In a mathematical expression:
3. Graph: See the attached graphic. Where y-axis (vertical) represents the defense cards and x-axis (horisontal) represents the offense cards.

Answer is 11/15
This is the answer
First thing to remember is that they were currently in week 0, when they began saving:The equation for Alex would look like: y=20x + 125 See that we are on week 0, and x is our weeks, and the equation would look like: y=20(0) + 125 Simplifying the equation, it will give us which it is y = 125That means that the first one is E. 125For the second, it shows our week 0, which is at 100.That means that the second one is I. 100
