\text{Plug in 0 to h(x) and solve:}\\\\0=3x-7\\\\\text{Add 7 to both sides}\\\\7=3x\\\\\text{Divide both sides by 3}\\\\\frac{7}{3}=x\\\\\boxed{\frac{7}{3}=x}

h(x)=3x-7

And we are given that h(x)=0 and want to find the value of x. Set h(x) to 0 and we get the equation:

3x-7=0

Add both sides by 7

3x=7

Divide both sides by 3

x=\dfrac{7}{3}

This is the answer (as an improper fraction). Let me know if you need any clarifications, thanks!

The outside temperature decreases by 7F in 3 1 2hours. Part A How would you represent the temperature change as a unit rate? Exp
Evgesh-ka [11]

Answer:

A)  2f / hour

B) 10 f

Step-by-step explanation:

outside temperature decreases by ; 7 F in 3 1/2 hours

a ) represent temperature change as a unit rate

To do this you will need to represent the temperature change per hour

7 f / 3.5 hours

= 7 f / 3.5 = 2 therefore the temperature change as a unit rate = 2f / hour

b) Temperature change after 5 hours

Δ temperature  in 5 hours = temperature change per hour * 5

                             = 2 F * 5 =  10 F

Absolute value of (0, -4/5)
Crazy boy [7]

To answer this question, we need to know what absolute value is in the first place. <u><em>ANSWERS ARE AT THE BOTTOM.</em></u>

Absolute value represents how far something is from 0 in a number line.

For example, lets take 4.

4 is 4 units away from 0 on the number line, so the absolute value of 4 is 4.

Now lets look at another example, -4. -4 is also 4 units away from 0, just in the other direction. However, when calculating absolute value, we do not care about the direction. Therfore, the absolute value of -4 is also 4.

Now let's look at your problem.

You want the <em>absolute value</em> of 0 and -4/5

<u><em>Following the same principle above about the distance from 0, here are your answers:</em></u>

<u><em></em></u>

<u><em>Absolute value of 0</em></u><u><em>: </em></u><em>0</em>

<em></em>

<u><em>Absolute value of -4/5</em></u><u><em>: </em></u><em>4/5</em>

True or false questions for the following graph:
ad-work [718]

9514 1404 393

Answer:

  • false
  • true
  • false
  • false

Step-by-step explanation:

The roots (zeros) of the function are (1, 0) and (3, 0). The point (2, 2) is the vertex, the maximum in this case.

The domain of any polynomial function is "all real numbers".

The range is y ≤ 2, not y < 2.
