Step-by-step explanation:
<em>Given:</em>
<em>Which expression is equivalent to -6x + 7.5?</em>
<em>Solution:
Going through all answer choices:</em>
<em>[A] -3(2x-2.5)</em>
<em>Simplify</em>
<em>-6x + 7.5</em>
<em />
<em>[B] -3(2x + 2.5)</em>
<em>Simplify</em>
<em>-6x - 7.5</em>
<em />
<em>[C] -3(2x-7.5)</em>
<em>Simplify</em>
<em>-6x+22.5</em>
<em />
<em>[D] -3(2x + 7.5)</em>
<em>Simplify</em>
<em>-6x - 22.5</em>
<em />
<em>Hence, the answer is [A] -3(2x-2.5)</em>

<h2>The chances of receiving two greens are 5/31.</h2>
<em>Given a bag containing four blue, three red, and five green marbles, the total result is:</em>
<em>Total number of balls = 4 + 3 + 5 = 12</em>
<em>If green is chosen first, the chances of picking a green are 5/12.</em>
<em>The probability that the second stone is green is 4/11 if it is picked and not replaced (4 greens remaining)</em>
<em>The chance of earning two greens is 5/12 4/11.</em>
<em>The chance of getting two greens is 20/132.</em>
<em>The chance of earning two greens is 5/31.</em>
<h3>
<em>As a result, the chance of getting two greens is 5/31.</em></h3>
F(x)=x/x²+2
So... f(x)=1/x+2
Therefore:
f(-x)=1/(-x)+2=-1/x+2
Answer: Y = 4
the output is 4
Step-by-step explanation:
substitute the given input value, 3, for x and solve
Y= 10 -2x
Y = 10 -2(3) multiply -2 × 3 to get -6
Y = 10 -6 . subtract
Y = 4
Answer: 95 Windows
Work: So, before we can do anything, we need to find out how many windows he can do in 1 hour. To do this, we divide 38 by 2. After this equation, he can do 19 windows in 1 hour. Multiply 19 by 5 to find out how many windows he can do in 5 hours, and you get 95 windows. I hope this helps. :)
