padilas [110]

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:

y=2x

3. Graph: See the attached graphic. Where y-axis (vertical) represents the defense cards and x-axis (horisontal) represents the offense cards.

How do you solve -3+r/3=-5
MAVERICK [17]

Answer:

r=-6

Step-by-step explanation:

Question: -3+r/3=-5

1) Multiply both sides of the equation by 3:

-9+r=-15

2) Add 9 to both sides:

r=-6

Footnotes:

1) In step 1 when I multiplied both sides of the equation by 3, don't forget you also have to multiply -3 by 3 because it is not part of the fraction (which is how I got -9)

Write the first 4 terms of the sequence defined by the given rule f(n)=n2 -1
Softa [21]

Answer:

<h2>0, 3, 8, 15</h2>

Step-by-step explanation:

Substitute n = 1, n = 2, n = 3 and n = 4 to the equation f(n) = n² - 1:

f(1) = 1² - 1 = 1 - 1 = 0

f(2) = 2² - 1 = 4 - 1 = 3

f(3) = 3² - 1 = 9 - 1 = 8

f(4) = 4² - 1 = 16 - 1 = 15
