Are you to combine the answer or are they 2 separate equations you need to solve for y?

Since both equal x, just subsitute them
3y-1=x=-2y+9
3y-1=-2y+9
add 2y to both sides
5y-1=9
add 1 to both sides
5y=10
divide both sides by 5
y=2

sub back into any equation
x=3y-1
x=3(2)-1
x=6-1
x=5

x=5
y=2

Help. only questions 3 & 4 .
Maksim231197 [3]

I'm doing 3

     For 3, using a table is very similar to a double number because the numbers are matching up in both ways.

         On the bottom of a double number line we have like, for example,-- the bottom of the double number line would have batches. And its 1, 2, 3 ,4 , etc.

         And on a table, it would be the same, the numbers on both diagrams have the same methods, have same way of lining things up but they're just drawn differently.

                Hope this helped!

Answer:

1. Tectonic activity is responsible for some of Earth's most dramatic geologic events: earthquakes, volcanoes and deep ocean trenches can all be formed by tectonic activity in the lithosphere.

2.The lithosphere can affect the atmosphere when tectonic plates move and cause an eruption, where magma below spews up as lava above. This can also release copious amounts of volcanic ash or soot, which pollutes the atmosphere, blocks radiation and creates a cooling effect.

3. I don't know what's show on the text sorry that parts up to you good luck :)

the equation y=0.5x represents the distance henry hikes, in miles, over time, in hours. the graph represents the rate that clark
zheka24 [161]

I think there's supposed to be a picture here. Anyway, you can find out by finding the slope of the line on the graph and comparing it to .5 which is Henry's slope. If the graphed slope is larger than .5 then Clark hikes faster, if it is less than .5, Henry hikes faster.

Hope this helps :)
