Slope: -4/3
y+1=-3/4(x-4)
y+1= -3/4 +3
y= -3/4x +2
Answer:
Kevin's estimate is incorrect. When x=4, the value of y is $116, which is not close to
$180.
Step-by-step explanation:
The equation 
equals to 
Step-by-step explanation:
We need to solve the equation:
Solving:
Adding 9 on both sides
Applying absolute rule: |u| < a and a > 0 then, -a < u < a
So, 
Now we have,
m-8>-9 and m-8 <9
m>-9+8 and m <9+8
m>-1 and m<17
Combining the intervals:
-1 < m < 17
So the equation equals to

Answer:
a
Step-by-step explanation:
Direct proportion is when two numbers move in the same direction. If one of the numbers increase, the other number increases and if the one of the numbers decrease, the other number decreases. The magnitude of the movement of the numbers is bounded by a constant
The expression for direct proportion is
y ∝ kx
where k is the constant
let illustrate with an example :
If x = 10
k = 4
y = 10 x4 = 40
Answer:
55°
Step-by-step explanation:
Angles x and 125° are linear pair,
So,
x + 125° = 180°
x = ( 180 - 125 )°
x = 55°
