Written in 2-point form, the equation of the line is
y = (y2-y1)/(x2-x1)·(x-x1) +y1
y = (3-(-5))/(-6-(-4))·(x-(-4)) + (-5)
y = 8/-2·(x +4) - 5
y = -4x -21
The value of b is -21.
4 minutes 12 seconds is 252 seconds
3 minutes 54 seconds is 234 seconds
252 seconds for 462 beats is in proportion with 234 seconds with some number of beats
Set up the proportion:
⇒
⇒
⇒
So the new song has 429 beats.
Answer:
x = 4, x = 8
Step-by-step explanation:
Given
(x - 7)(x - 5) = 3 ← expand factors using FOIL
x² - 12x + 35 = 3 ( subtract 3 from both sides )
x² - 12x + 32 = 0 ← in standard form
(x - 4)(x - 8) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x - 8 = 0 ⇒ x = 8
If you are going from a larger unit to a smaller unit, you multiply. If you are going from a smaller unit, you divide
I believe the answer is 420
