Answer:
x = 6, x = - 6
Step-by-step explanation:
Given
y = x² - 36
To find the zeros let y = 0, that is
x² - 36 = 0 ← x² - 36 is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
x² - 36 = 0
x² - 6² = 0
(x - 6)(x + 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 6 = 0 ⇒ x = - 6
In standard form the two equations are
7x +y = 5
7x +y = -5
The equations describe lines that are parallel.
Answer : - 4 + 3 = - 1
- 2 + 3 = 1
By half gives - 1/2 and 1/2
So midpoint (-1/2, 1/2)
The answer is the second option given
The equation for interest is
'Initial amount (interest rate in decimal form) ^ times compounded EX: years'
your equation would be
400(1.04)^10
which equals 592.097713 (not rounded)
