Answer:
y = - 3x + 16
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 8 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 3, so
y = - 3x + c ← is the partial equation of the perpendicular line
To find c substitute (6, - 2) into the partial equation
- 2 = - 18 + c ⇒ c = - 2 + 18 = 16
y = - 3x + 16 ← equation of perpendicular line
Answer:
Therefore 164 children and 89 adults swam at the public pool that day.
Step-by-step explanation:
Given that,
253 people used the public swimming pool.
The daily prices for children are $1.50 and for adults are $2.25.
Let the number of children be x.
Then number of adult is (253-x)
The total money collect on that day is
According to the problem,
Therefore 164 children and (253-164)=89 adults swam at the public pool that day.
