To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

Answer:
their distance is increasing at the rate of 41.6 miles/hr
Step-by-step explanation:
Given the data in the question;
first we determine the distance travelled by the first boat in 10 min when the second boat was crossing its path;
⇒ ( 30/60 ) × 10 = 5 miles
so as illustrated in the diagram below;
y² = x² + ( x + 5 )²
2y
= 2x
+ 2(x+5)
y = ( 2x + 5 ) ]
= [( 2x + 5 )/y ] ------ let this be equation 1
Now, given that, = 30 miles/hr, when x = 10
so
y = √( 10² + 15² ) = √325
so from equation 1
= [( 2x + 5 )/y ]
we substitute
= [( 2(10) + 5 ) / √325 ]30
= [ 25 / √325 ] × 30
= 41.6 miles/hr
Therefore, their distance is increasing at the rate of 41.6 miles/hr
Answer:
ther overall average would be 36
Step-by-step explanation:
If O is the orthocenter, O=(xo, yo)
such that xo=(2+0 + 2)/3, so xo= 4/3, so the answer must be
