Idon’t really understand how to do the equation! due to tomorrow !

the equation means that overall the distance is 200 miles per a hour the car has 2 speed it travels at. Sometimes it will travel at 35 miles per a hour and sometimes it will travel at 55 miles per a hour.

Step-by-step explanation:

ex.

55(3)+35y=200

165+35y=200

35y=35

she will spend 1 hour going at 35 mph

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
