Answer: Choice B)
2x+5(2x+3) = 3
============================================
Reasoning:
We start with the second equation 2x+5y = 3
Since y = 2x+3 from the first equation, we can replace every copy of y with (2x+3). This replacement is valid because y and 2x+3 are the same.
So that's how we go from 2x+5y = 3 to 2x+5(2x+3) = 3
This replacement is done to get rid of the y variable, and it allows us to solve for x later on.
Answer:
(0,0) and (5,0)
Step-by-step explanation:
i dont know your choices
20x^4-39x^3-16x
Make sure to multiply all the terms by each other in the two parentheses
Answer:
X ≥ 3.5
Step-by-step explanation:
-2x-6≤1
+6 +6
-2x≤7
-2x/2 7/2
x ≥ 3.5
So for this function we will be using the quadratic formula, which is 
, to solve. a = x^2 coefficient, b = x coefficient, and c = constant. Using our equation, we can solve for the zeros (x-intercepts) as such:
In short, your x-intercepts (rounded to the hundredths) are (1.92,0) and (-3.92,0).
