Answer:
2
Step-by-step explanation:
Step-by-step explanation:
f(x) = x² - 4x - 4
the general formula for solving such a quadratic equation (for f(x) = 0) is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = -4
c = -4
x = (4 ± sqrt(4² - 4×1×-4))/(2×1) = (4 ± sqrt(16 + 16))/2 =
= (4 ± sqrt(2×16))/2 = (4 ± 4×sqrt(2))/2 = 2 ± 2×sqrt(2)
x1 = 2 + 2×sqrt(2)
x2 = 2 - 2×sqrt(2)
Answer:
The answer would be <em>3</em><em>4</em><em>2</em>
Step-by-step explanation:
<em>Multiply </em><em>1</em><em>9</em><em> </em><em>by </em><em>1</em><em>8</em><em> </em><em>and </em><em>you </em><em>get </em><em>3</em><em>4</em><em>2</em>
Answer:
y= 3x + 1
Step-by-step explanation:solve for y
subtract 3x from the left which leaves -y= -3x -1
then you have to take flip the signs or divide by -1 so it comes out to y=3x + 1
