Step-by-step explanation:
remember it says which of the following equations can be used to determine NOT how much she will have after "w" weeks so it is not A.
C. is wrong because the 40 is supposed to come before the 20.
The percentage would be would be 550%
This polynomial does not factor so you have to complete the square or use Quadratic formula.
x^2 + 6x + 7 = 0
Using completing the square, subtract 7 from both sides.
x^2 + 6x = -7
divide 6 by 2 = 3, square 3 = 9, add 9 to both sides.
x^2 + 6x + 9 = 2
(x + 3)^2 = 2
Take the sqrt of both sides
x + 3 = + - sqrt 2
subtract 3 from both sides
x = - 3 + - sqrt 2
This is not an answer choice but it is the correct answer. You either typed the choices incorrectly or the equation incorrectly.
Answer:
y-6=-3/4(x+4)
Step-by-step explanation:
y-y1=m(x-x1)
m=-3/4
y-6=-3/4(x-(-4))
y-6=-3/4(x+4)
Answer:
it will be 634.24 because if you add 551.02 and 93.22 that will be 644.24 then you minus the 10 at the beginning.
