Well i don't know if this will help but slope intercept form
y=mx+b
M-slope
B-Y intercept
and
(x,y)- would be any point on the graph and if you were to plug those points in for x and y the equation would solve if done properly
So first we need to find what percent of the students walk to school.
50 + 35 = 85% don't walk leaving only 15% that walk to school,
To find the 15% percent that DO walk we multiply .15 by the total number of people.
.15 x 1640 = 246 people walk to school

Answer:

Step-by-step explanation:
Recall the negative angle identity for the sine function:
Then, we can find the value of
:

Now recall the definition of the tangent function:

Therefore, now that we know the value of
, we can solve in this equation for 

Answer:
Speed of plane in still air = 135 km/h
Speed of wind = 23 km/h
Step-by-step explanation:
Given that:
Speed of plane with the wind = 158km/h
Speed of plane against the wind = 112km/h
Let,
x be the speed of plane
y be the speed of wind
According to given statement;
x+y = 158 Eqn 1
x-y = 112 Eqn 2
Adding Eqn 1 and 2

Putting x = 135 in Eqn 1
135+y = 158
y = 158-135
y = 23
Hence,
Speed of plane in still air = 135 km/h
Speed of wind = 23 km/h
