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

Hope this
When x = 1, y = 1 + 4 = 5
When x = 3, y = 3 + 4 = 7
When x = 5, y = 5 + 4 = 9
When x = 7, y = 7 + 4 = 11
Therefore, the correct answer is option D.
31°
Angles in the same segment are similar.
I'm not too sure how to explain, but in a circle when two "triangles" are formed from two same points on the circumference, the angle of the vertexes formed are the same (like in the picture)
Answer
Y= 2 x= -0.645
Step-by-step explanation:
you basically plug 0 into x and y
y=1.29(0)+ 2
y=2
0=1.29x+ 2
