Given: x + y = 10.

GIVEN X+Y=10

If x = -21, what is y?

-31
31
11

y = 31

Step-by-step explanation:

We'll, if x + y = 10,

and x = -21,

then: -21 + y = 10.

To solve, add 21 on both sides to get y = 31

Hope this helps :)

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
