use mathaway or algebra calculator they help alot
Answer:
The equation of the perpendicular line would be y = -2/5x - 1
Step-by-step explanation:
In order to find this line, we must first find the slope of the original line. We do this by solving for y.
-5x + 2y = -10
2y = 5x - 10
y = 5/2x - 5
This shows us a slope of 5/2. TO find the perpendicular slope, we use the opposite and reciprocal. This means we negative 5/2 to get -5/2 and then we flip it to get -2/5. Now that we have this, we can use the slope and the point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 1 = -2/5(x + 5)
y - 1 = -2/5x - 2
y = -2/5x - 1
Answer:
yes it is rational, as it can be expressed in the form p/q where p=-2 and q=3
Step-by-step explanation:
27x^3-108x^2y+144xy^2-64y^3
A.
First you have to evaluate (2000* .045) then you take that and multiply by 8 then you add the answer to 2000.
so 2720 is your answer.
