Hi!

<h3>We need to isolate y on one side. </h3><h3>Subtract 2x from both sides. </h3>

2x - 2x + 2y = -2x + 4

2y = -2x + 4

<h3>Divide by 2 on both sides. </h3>

2y/2 = -2x/2 + 4/2

<u>The slope is -1/1. </u>

<u>The y intercept is 2. </u>

<h2>So the answer is D. (the last one)</h2>

Hope this helps! :)

Hey there!

Your answer: Graph D

We would want to find the graph that would stay positive, and not negative. As we look at Graph D, it moves 2 from the right, and also 2 up. Which indicated both 2x+2y=4

Answer: Graph D

Answer:

x = 5

Step-by-step explanation:

$\frac{10}{x} = \frac{14 + 10}{2x - 3 + x}$

$\frac{10}{x} = \frac{24}{3x - 3}$

$24 x = 10 . (3x - 3)$

$24x = 30 x - 30 \\6x = 30 \\x = 5$

Select "Growth" or "Decay" to classify each function.

A) y=1/2(2.5)^t/6 is the only growth function, the other two are for decay as the multipliers in the brackets are less than 1, thus indicating decay
C) 20(1.2)^4= 41 views
D) A and C as the multipliers in the brackets are less than 1, thus indicating decay

If an average person in the United States throws away 4.5 × 10² g of trash per day and the number of persons is <span>3.2×10^6, then the mass of trash thrown away in United States would be 1.44 x 10^9 grams. This is obtained by multiplying the mass of trash thrown by one person to the number of persons in the U.S.</span>
