Answer:
Step-by-step explanation:
If you call "5x-2x^2+1" an "equation," then you must equate 5x-2x^2+1 to 0:
5x-2x^2+1 = 0
This is a quadratic equation. Rearranging the terms in descending order by powers of x, we get:
-2x^2 + 5x + 1 = 0. Here the coefficients are a = -2, b = 5 and c = 1.
Use the quadratic formula to solve for x:
First find the discriminant, b^2 - 4ac: 25 - 4(-2)(1) = 25 + 8 = 33
Because the discriminant is positive, the roots of this quadratic are real and unequal.
-b ± √(discriminant)
Applying the quadratic formula x = --------------------------------
2a
we get:
-5 ± √33 -5 + √33
x = ----------------- = --------------------- and
2(-2) -4
-5 - √33
---------------
-4
Answer:
Y= 10x-24 would be parralel to y=10x+6
Step-by-step explanation:
well a parralel line has to have the same slope and a different y-intercept.
To find the y-intercept the x has to be exactly 0.
So we have (2,-4)
The slope is 10/1 which is 10y and 1 x which in an ordered park would be Add 1 x and add 10 y. But we’re trying to get x to be 0 to find the y-intercept.
So subtract 1 x and subtract 10y
2-1=1
-4-10=-14
(1, -14)
1-1=0
-14-10=-24
(0, -24)
THe y-intercept is -24 and w have the slope since its the same thing So
y=10x-24 is the equation
