Answer:
For the one including 4w the answer is - 7
The one with n/2 is - 12
Step-by-step explanation:
4w=-13-15
4w=-28
w=-7
Multiply by 2 on both sides
-24=n-12
-24+12=n
Always write it in the variables perspective.
n=-12
Answer:
40/100=4/10=2/5 2/5 is the simplest form
Answer:
a)
b)
c)
Step-by-step explanation:
From the question we are told that:
Angle 
a)
Generally the equation for Slope is mathematically given by



b)
Given the right Angle triangle with horizontal distance 
Generally the equation for Height traveled is mathematically given by




c)
Generally the equation for Horizontal Distance traveled at 313 height traveled is mathematically given by



Given parameters:
y varies directly as w;
This interpreted implies that as y increases, we increases by a certain factor or amount;
So, y ∝ w
y = kw
where k is the constant of proportionality
Now, given that y = 8 and w = 2
Input in the equation to solve for k;
8 = k x 2
Solving k gives, k = 4
Now to the second part,
if v is directly proportional to w;
v = k w
So v = 4w
The equation that relates v to w is v = 4w
Answer:
Rate of change: -3.5
Step-by-step explanation:
(-3,10.5) and (-2,7)
(7 - 10.5) / ( -2 - - 3)
= -3.5 / 1
