Answer:
x = 3, x = 6
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log (
)
log
⇔ nlog x
x = n ⇔ x = 
Given
2
x - (x - 2) - 2 = 0 ( add 2 to both sides )
x² - (x - 2) = 2
(
) = 2
= 3² = 9 ( multiply both sides by x - 2 )
x² = 9(x - 2) ← distribute
x² = 9x - 18 ( subtract 9x - 18 from both sides )
x² - 9x + 18 = 0 ← in standard form
(x - 3)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 6 = 0 ⇒ x = 6
Answer:
A and G
Step-by-step explanation:
100 percent means all of whatever number over again. This means that you double it, meaning it would double or be 200 percent of what it once was.
Y + 7 = -4(x - 2)
The equation for point slope form is
y - y1 = m(x - x1) where m represents the slope.
It coordinates and slope are given, they just need to be plugged into the equation.
y - (-7) = -4(x - 2)
Subtracting a negative can be written as adding a positive, so the equation can be simplified as:
y + 7 = -4(x - 2)
A linear function is y=mx + b so yes (assuming + sign at end is accidental)
