Answer:
Step-by-step explanation:
Using quadratic formula
we will have two solutions.
2x^2 - x - 4 = 0
So, a=2 b=-1 c=-4, we have:
Finally, we have two solutions:
Answer:
See below.
Step-by-step explanation:
Equation of parabola:
y = some expression in x^2
To translate the parabola vertically, substitute y with y - k.
The translation is k units vertically. If k is positive, the translation is up. If k is negative the translation is down.
Example 1:
original parabola: y = x^2 - 2x + 5
To translate it 3 units up, we need k = 3.
Substitute y with y - 5 to get
y - 3 = x^2 - 2x + 5
y = x^2 - 2x + 8 is the equation of the parabola translated 3 units up.
Example 2:
original parabola: y = 2x^2 + 4x - 6
To translate it 5 units down, we need k = -5.
Substitute y with y - (-5), or y = 5 to get
y + 5 = 2x^2 + 4x - 6
y = 2x^2 + 4x - 11
y = 2x^2 + 4x - 11 is the equation of the parabola translated 5 units down.
Answer:
6.1
Step-by-step explanation:
If we are rounding at the 0 digit, we look at the next digit, which is 9
9 >= 5 so we need to round the 0 up to 1
6.099 rounds to 6.1
Answer:
no
Step-by-step explanation:
Substitute x = 0 into the equation and if the value is 1 ( the y- coordinate ), then it is a solution.
y = 5(0) = 0 ≠ 1
Then (0, 1 ) does not satisfy the equation
