Answer:
(- 2, 0 ), (1, 0 )
Step-by-step explanation:
Given
y = 2x² + 2x - 4
To find the x- intercepts let y = 0, that is
2x² + 2x - 4 = 0 ← divide through by 2
x² + x - 2 = 0 ← in standard form
(x + 2)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1
Thus x- intercepts are (- 2, 0) and (1, 0)
3.1
First, we need to convert 10/100s into a decimal. We can simplify it to 1/10, which is also 0.1.
Then, we add 0.1 to 3 and get our answer: 3.1.
Hope this helped!
Since a nickel is worth 10 cents, you would make it times .10
The answer is that x equals 53.
