A waterslide is 4.2 m high and has a support 2.4 m tall. If a student reaches this support
Alex Ar [27]
Assuming that it's at the same angle the whole way, she goes 1.8 meters down in 3.1 meters down the slides, and if we divide 3.1 by 18 we can find how long the slide is for every 0.1 meter down, which is around 0.17. Multiplying that by 42, we get 7.23 (3 repeating) meters of the slide

Which geometric shape can be described as a fixed distance along a line?
saul85 [17]
Hey there!

A fixed distance along a line without any 2nd dimension is a line segment. The reason why it's a line <em>segment</em> instead of a line is that lines go on forever in both directions while a line segment stops at some point on both ends. This is what the problems means when it says "fixed distance". 

Hope this helped you out! :-)

What is the result of subtracting the second equation from the first? \begin{aligned} -7x-y &amp;= 0 \\\\ 7x+8y &amp;= -6 \end{a
Kitty [74]

Answer:

-14x-9y=6

Step-by-step explanation:

We are given with two equations

first equation is  -7x-y=0

second equation is

7x+8y=-6

we find the result of subtracting two equation

subtract the second equation from the first, so

first equation - second equation, multiply second equation by -1  and then add it with first equation

-7x-y=0

-7x-8y=+6

Now add both equations, we get

-14x-9y=6
