Answer:

Step-by-step explanation:

$5 \sqrt{x} -6=-20$

1. You divide 5 by both sides, which will give you $\sqrt{x-6}=-4$

2. You then square both sides of the equation, which will give you $x-6=16$

3. Since the equation is now one-step, you then do GEMDAS and you will get x=22

Find the unit rate.<br> 180 miles in 3 hours

leva [86]

Answer:

60 miles per hour

Step-by-step explanation:

First, put the equation in a fraction.

You would put 180 up top because people always say miles per hour not the other way around.

You can see the dividing line as your "per" and your "hour" would be the bottom number.

To find the unit rate, you will divide the numerator (180) and the denominator (3).

Your final answer should be 60 miles per hour.

$\frac{180}{3} = \frac{60}{1}= 60$

. Could someone please explain this to me in detail. I am very confused. Thank you so much!. . A candle is 17 inches tall after

andrew-mc [135]

The generic equation of the line is:

$H-H0 = m (T-T0)$

Where,

m: slope of the line

(T0, H0): ordered pair belonging to the line.

The slope of the line is:

$m =\frac{H2-H1}{T2-T1}$

Substituting values we have:

$m =\frac{15-17}{5-3}$

Rewriting:

$m =\frac{-2}{2}$

$m = -1$

Then, choosing an ordered pair we have:

$(T0, H0) :( 5, 15)$

Substituting values we have:

$H-15=-(T-5)$

Rewriting the equation:

$H-15=-T+5$

$H=-T+5+15$

$H=-T+20$

Then, for 8 hours we have:

$H=-8+20$

$H=12$

Answer:

a linear equation to model the relationship between height H of the candle, and T time is:

$H=-T+20$

the candle will be 12 inches after burning 8 hours
