Answer:

Perpendicular with respects to what?

You can't find it with only a point, you also need a slope to know which line is which.

There are an infinite number of lines that go through any point. Each has a slope, without slopes, we cant solve such a question.

It's line asking, how old is Jane's dog?

Who knows man? There's like thousands of Janes, which one is the one?

Answer:

x=square root 63. Basically the radical 63.

Step-by-step explanation:

So in the first triangle with the 3 in it. You have root 3 and use the a^2 +b^2=c^2 formula. So 3^2 + 3^2= x^2 and then when you solve you get radical 18^2 which is equal to radical 18 or square root 18. Then we go to the bigger triangle and we do the same formula but this time we have the c value which is 9. So we do radical 18^2 + x^2 = 9^2 and then solve that and minus 18 from the 81 since the radical goes off the 18 and you get square root63.

Sorry i couldn't use the signs. Sorry If I'm wrong Hope this helps!.

How do I write the sum of 6x and 2x is at least 39 ?

tatiyna

<h2>Put x = $\dfrac{39}{8}$ I write the sum of 6x and 2x is at least 39 .</h2>

Step-by-step explanation:

We have,,

6x and 2x

To find, the value of x = ?

According to question,

The sum of 6x and 2x is at least 39

∴ 6x + 2x = 39

⇒ 8x = 39

⇒ x = $\dfrac{39}{8}$

∴ The value of x = $\dfrac{39}{8}$

Thus, put x = $\dfrac{39}{8}$ I write the sum of 6x and 2x is at least 39 .

Laura drove 638 miles in 11 hours at the same rate how long would it take her to drive 406 miles

shusha [124]

Answer:

Step-by-step explanation:

This is a d = rt problem; but since it is linear, then proportions will work too. Set up the proportion with miles on top and hours on the bottom:

$\frac{miles}{hrs}:$

Then put the numbers in where they go, keeping in mind that miles goes with miles and hours goes with hours in the ratios, and that our unknown is time (hours):

$\frac{miles}{hrs}:\frac{638}{11}=\frac{406}{x}$ and cross multiply to solve:

638x = 4466 so

x = 7 hrs
