It’s clearly number 2. 3 and 4 don’t have a 4 so it leaves 1 and 2 1 has gt so that’s wrong so it’s 2 because it has lt
Answer:
A. and C.
if you simplify the expressions, you will see which ones are equal to the expression given
Answer:2
Step-by-step explanation: the equation is in linear form y=mx+b, the b represents the y intercept in your equation that would be -5
Answer:
Step-by-step explanation:
Although you can start with 4x^2-2x-4=0, it's just slightly easier to reduce the coefficients. 4x^2-2x-4=0 becomes 2x^2 - x - 2 = 0.
The discriminant (part of the quadratic formula) is b^2 - 4ac. Using b = -1. a = 1 and c = -2, we get (-1)^2 - 4(2)(-2), or 17.
-b ± √(b^2 - 4ac)
Then the quadratic formula x = ---------------------------
2a
-(-1) ± √17 1 ± √17
takes on the values x = ----------------- = ---------------
4 4
