You are moving in the path of a parabola.
The conic section is parabolic - the street is the directrix and the mailbox is the focus.
Step-by-step explanation:
answer is in photo above
If x + y = 5 and 3x = 2 then what you
do is:
3x = 2 and since you want the variable by itself you’d divide by 3... giving you an answer of x = 2/3 BUT YOURE NOT DONE YET
so now you plug what x equals (2/3) into the equation x + y = 5:
2/3 + y = 5
to solve this you have to subtract each side by 2/3 so x = 5 - 2/3
(5/1 - 2/3.... to get like denominators multiply the nominator and the denominator for 5/1 by 3 giving you: 15/3 - 2/3 = 13/3)
your final answer would be 13/3
The slope of JK is -6/5.
The slope of PQ is 12/ 15.
These lines are neither parallel nor perpendicular.
<u>Step-by-step explanation:</u>
From the graph shown,
It can be determined that the point J is (0,5) and K is (10,-7).
The point P is (-5,-8) and Q is (10,4).
The formula for slope is given by,
Slope = 
<u>To find the slope of line JK :</u>
J ⇒ (0,5) = (x1,y1)
K ⇒ (10,-7) = (x2,y2)
Slope of JK = 
⇒ 
⇒ 
∴ The slope of JK is -6/5.
<u>To find the slope of line PQ :</u>
P ⇒ (-5,-8) = (x1,y1)
Q ⇒ (10,4) = (x2,y2)
Slope of PQ = 
⇒ 
∴ The slope of PQ is 12/ 15.
<u>To find the relation between two lines :</u>
- The parallel lines have same slope.
- The perpendicular lines have a slope of negative reciprocal.
∴ These lines are neither parallel nor perpendicular.
