5x + 2y = 30
x + y = 8 <==== multiply by -2
--------------
5x + 2y = 30
-2x - 2y = -16 (result of multiplying by -2)
-------------add
3x = 14....u see how multiplying by -2 will eliminate the y's

HELP PLS 25 POINTS!!!!
Anika [276]

Okay, let me first explain what the equation<em> y = 8.77x + 686 </em>means

<em>y </em><em>is the hikers elevation </em>

Look at the graph and see what the y and x axis's are labeled as.

<em>x </em><em>is time. </em>

8.77 is just the slop of the trend line.

<em>686 </em><em>is just the elevation the hiker starts at</em>, or in technical terms, the y intercept. Y intercept is just where the lines touches the y axis.

The question asks what will be the <u>hiker's elevation at 145 minutes. </u>

To solve, just simply <u>plug in 145 as X </u>in the equation above. Remember x is time.

It will look like this :

y = 8.77 (145) + 686

Then solve.

y = 1271.65 + 686

y = 1957.65

Reminder: They want the nearest whole number!

Round 1957.65 feet to 1958 feet
