X+1825=y^2
sqrt（1825）=42.8
so the least is y^2=43^2=1849
so x=1849-1825=24

Step-by-step explanation:

12) y = 4 + 7x

x = 3,-1

y = 4 + 7(3) = 25

13) y = x - 11

x = 72,

y = 72 - 11 = 61

14) y = 6x - 5

y = 6(-4) - 5 = -29

y = -11 (x = -1)

y = -5 (x = 0)

y = 13 (x = 3)

15) y = x + 1, each relation is a function

16) An = 22 + (n-1)11

A(2) = 22 + 1(11) = 33

A(5) = 22 + 4(11) = 66

Simplify and determine the coefficient of (-2/5x)(5y)(-2x).

Juli2301 [7.4K]

Solution/Answer : 4

Solution: the first you do is multiply the last two parentheses to get -10xy

Now we are left with ( -2/5x)(-10xy)
Then we multiply that out into
(-2*-10)/5*x^2y = 20/5x^2y =
4x^2y

The coefficient in this case would be four. (In case you were confused about what a coefficient actually is, it’s the number you multiply a variable by)

Hopes this helps :)
