Answer:
yes, that is the correct answer. X is domain and Y is range so you are correct.
Step-by-step explanation:
3t-7=5t
-3t -3t
-7 = 2t
/2 /2
t = -7/2
Plug it in to 6t, so it is 6(-7/2) = -21
Point slope form is:
y − y

= m(x − x

)
Where x

and y

are two known coordinates and m is the slope.
Substitute (4,2) as x and y and 3 as m to find the point-slope form.
<span>
y − 2 = 3(x − 4)</span>
Taking it to the next step would be to turn this into slope-intercept form, y=mx+b
<span>y − 2 = 3(x − 4)
y</span> − 2 = 3x − 12
y = 3x − 10
Perhaps we can treat this as a "distance to horizon" problem, the observer is 7 mi above the earth
One formula is: d+=+sqrt%28%283h%29%2F2%29 where d is in miles and h is in feet
Change 7 mi; 5280*7 = 36960 ft
so we have
d = sqrt%28%283960%2A3%29%2F2%29
d ~ 235.5 mi
looking in opposite directions a total of 2*235 = 471 mi can be viewed
Find the circumference of the earth
C = pi%2A8000
C = 25133 mi
:
The arc: 471%2F25133 * 360 = 6.7 degrees

This should be pretty close, because the earth is so large compared to the altitude. would appreciate if it you would let me know. C
