H(10)=210-15(10)
h(10)=210-150
h(10)=60
The hot air balloon is at an altitude of 210. The hot air balloon slowly falls 15 () per minute, for 10 minutes. He ends up at 60 altitude
Answer:
The x represents the value of the point on the x axis or the horizontal line, and the y represents the vertical line. Now, lets solve for the first point. We can first see that it only moves to the left by two from zero, which is basically -2. So, right now we have (-2,y). We then look for the y in which we see that it is down -6 from zero, so it will be (-2,-6). Time to look for the second point. We should get (2,-3). Now, with these two points, it is time to find the slope intercept form.

Answer:
x= 1 , y=4
Step-by-step explanation:
x-y= -3 => Equation 1
x+5y= 21 => Equation 2
<u>Substitut</u><u>ion</u><u> </u><u>Method</u><u>:</u>
<u>Substitu</u><u>te</u><u> </u><u>Equation</u><u> </u><u>1</u>=>
x=y-3 <= Equation 3
Put x=y-3 in Equation 2:
x+5y=21
( y-3)+5y=21
y-3+5y=21
6y-3=21
6y=21+3
6y=24
y=24÷6
y=4
Put y=4 in Equation 1:
x-y= -3
x-4=-3
x=4-3
x=1
Hope this helps :)
Answer:7
Step-by-step explanation:
To find the median you need to first put the number in order from least to greatest this would be 2, 4 ,5, 7, 7, 7, 8
next you have to find the number in the middle
That is your median, 7 is your median.
This is exactly like the one with the 'n's that you posted yesterday.
I guess you didn't get enough help on that one to understand it.
<span><u>7k/8 - 3/4 - 5k/16 = 3/8</u>
3/4 is the same as 6/8.
Add it to each side of the equation:
7k/8 - 5k/16 = 9/8
Multiply each side by 16 :
14k - 5k = 18
Add up the 'k's on the left side:
9k = 18
From this point, you can proceed directly to the numerical value of 'k'
if you need it.<u />
In your question, you said you need help, and I showed you how to
strip the problem down so that the only thing left is ' k = something '.
Giving you the answer is no help. Nobody actually needs the answer.
