Ax+by=c
a=(-by+c)/x
b=(-ax+c)/x
c=ax+by
x=(-by+c)/a
y=(-ax+c)/b. or y= -a/b x + c/b which is slope intercept form

Answer:
The first one is 1 and the second one is 1:00
Step-by-step explanation:
e set of words that refers to the clock is: midnight (exactly 12:00 am), morning (from 12:01 am to 11:59 am), noon (exactly 12:00 pm), afternoon (from 12:01 pm to 6:00 pm), evening (from 6:00 pm to 11:59 pm).
Answer:
As per the given statement:
The distance from jack eyes to the top of the tower = 50.64 m
Also, jack and john eyes are 1.5 m from the ground.
Labelled diagram as shown in the attachment
Let BC = x m be the distance of the jack from the base of the tower and
AG = y m be the distance above 1.5 m from the the ground.
Using tangent ratio:
In triangle AGE;
Here, AG = y m and EG = 20+x m
then;
or we can write this as;
........[1]
Similarly, in AGF;
then;
or
......[2]
Substitute equation [2] into the equation [1], to solve for x;
or
Using distributive property:
we have;
Subtract 0.84 x from both sides we get;
Divide both sides by 0.892 we get;
Therefore, 18.8 meter johns from the base of the tower.
