First eliminate the parameter of t from x(t)=3t+4
x-4=3t
(x-4)/3 =t
put in
<span>y=5-t
So,
y=5 - ((x-4)/3)
y=(15-x+4)/3
y=(19-x)/3
y= -x/3+19/3
option A is correct</span>

56756
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals
parallel lines have the same slope
Answer:
The area of the circle is 95.03.
Step-by-step explanation:
Diameter is double the radius.
The sum of the three angles of a triangle is always 180 degrees. If the triangle is right, which means one of the angles measures 90 degrees, the other two angles should add up to 90 degrees. With this condition and the given above, x + 15 + 2x = 90. Solving for x in the equation gives x = 25. Substituting x to the given expression for the acute angles gives the measurements of 40 and 50 degrees. Thus, the smallest angle of the triangle is <em>40 degrees</em>.
