Answer:
x= 
Step-by-step explanation:
9x-2=11x+5
-9x -9x
-2=2x+5
-5 -5
-7=2x
=x
H=v/(2pir)
You just have to isolate h. To do that you are going to divide both sides by 2pir.
Answer:
y = [-½]x + [-5]
Step-by-step explanation:
Equation describing how x and y are related can be written in slope-intercept form, y = mx + b.
m = slope = ∆y/∆x
Using two pairs of values from the table, (-2, -4) and (0, -5),
Slope (m) = (-5 - (-4))/(0 - (-2)) = -1/2
m = -½
b = y-intercept = the value of y when x is 0 = -5
b = -5
✔️To write the equation, substitute m = -½ and b = -5 into y = mx + b
Thus:
y = [-½]x + [-5]
