Answer:

2x² - xy - 15y²

Step-by-step explanation:

(2x + 5y)(x - 3y)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(x - 3y) + 5y(x - 3y) ← distribute parenthesis

= 2x² - 6xy + 5xy - 15y² ← collect like terms

= 2x² - xy - 15y²

Find the equation of the plane in xyzxyz-space through the point p=(5,5,3)p=(5,5,3) and perpendicular to the vector n=(1,2,5)

expeople1 [14]

Given that the plane is perpendicular to the vector <1,2,5>, this means that the normal vector of the plane is <1,2,5>.

Given that the plane passes through point (5,5,3), the equation of the plane is therefore:
Π : 1(x-5)+2(y-5)+5(z-3)=0
on simplifying, x-5+2y-10+5z-15=0
Π : x+2y+5z=30

PLS ANSWER IT I just need the answer

The y-intercept is (0,2)

you can find the y-intercept by finding the value of y when x = 0

The slope is -5/2.

you can find the slope by using the equation below and any two points on the line, such as (0,2) and (2,-3)

$\frac{y2-y1}{x2-x1}=\frac{-3-2}{2-0} =\frac{-5}{2}$

Hope that helps!
