Answer:
Step-by-step explanation:
Consider the quadratic expression
First, find its discriminant:
Note that then
Use quadratic formula to find the roots:
Now, given quadratic expression is equivalent to
Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (3, 0) ← 2 points on the line
m = = -
Note the line crosses the y- axis at (0, 1) ⇒ c = 1
y = - x + 1 ← equation of line
Simplify the following:(9 y)^2/(3 (3 y)^2 y^4)
Multiply each exponent in 3 y by 2:(9 y)^2/(3×3^2 y^2 y^4)
3^2 = 9:(9 y)^2/(3×9 y^2 y^4)
Multiply each exponent in 9 y by 2:(9^2 y^2)/(3×9 y^2 y^4)
9^2 = 81:(81 y^2)/(3×9 y^2 y^4)
(81 y^2)/(3×9 y^2 y^4) = y^2/y^2×81/(3×9 y^4) = 81/(3×9 y^4):81/(3×9 y^4)
3 | 2 | 7 | 8 | 1- | 6 | | 2 | 1- | 2 | 1 | | 0:27/(9 y^4)
27/9 = (9×3)/9 = 3:Answer: 3/y^4
Yikes. I believe it would be 186•10^3
If not, my apologies. I haven't done it in quite a while
