Answer:

x=-3

Step-by-step explanation:

So, we are given:

\frac{3}{x}=\frac{4x+3}{x^2}

First, we should immediately rule out 0 as an answer. This is because the if x=0, the equation would be undefined.

x\neq 0

Now, cross multiply.

3(x^2)=x(4x+3)

3x^2=4x^2+3x

Divide everything by x (and we can do this safely because we already know x cannot be equal to zero).

3x=4x+3

-x=3

x=-3

We didn't run into any possibilities for extraneous solutions.

On a very cold morning, it was -7°F. As the day went on, the temperature rose 3 degrees each hour. Which equation shows the temp
wariber [46]

Answer:

The equation shows the temperature over time will be:

  • y = 3x - 7

Hence, option (C) is correct.

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the rate of change or slope and b is the y-intercept

  • Let 'y' be the temperature
  • Let 'x' be the time in the hour

Given that one very cold morning, it was -7°F.

Thus, the y-intercept = b = -7

Given that as the day went on, the temperature rose 3 degrees each hour.

Thus, the rate of change = slope = m = 3

Thus, substituting m = 3 and b = -7 in the equation

y = mx+b

y = 3x + (-7)

y = 3x - 7

Therefore, the equation shows the temperature over time will be:

  • y = 3x - 7

Hence, option (C) is correct.

Please simplify this
REY [17]

Answer:

(√77) / 22

Step-by-step explanation:

To rationalize the fraction we must multiply the entire fraction by √11 / √11. Note that the 2 is not important because it's not a radical. This gives us √77 / 22.
