The expression (y-20)(y5)3 is equivalent to ya. What is the value of a?

Leno4ka [110]

Answer:

y¹⁵-20y¹⁴

Step-by-step explanation:

I'm going to assume that your problem looks like this

$(y-20)(y^5)^3$

$(x^n)^y=x^{n*y}$

which means we have

$(y-20)*y^{15}\\\\y^{16}-20y^{15}=ya\\\\*y^{15}-20y^{14}=a$

Which set of lengths are not the side lengths of a right triangle? (A-28, 45, 53) (B-13, 84, 85) (C-36, 77, 85) (D-16, 61, 65) [

nikklg [1K]

Side lengths 16, 61, and 65 are not part of a right triangle.

A right triangle's sides should follow this formula, C being the largest number:

$a^{2} + b ^{2} = c^{2}$

$16^{2} = 256$

$61^{2} = 3721$

$65^{2} = 4225$

256 + 3721 = 3977

$3977 \neq 4225$

Please Help!!<br> Write an equation of the line that passes through each pair of points.

Alex

Answer: y=-2x + 3

Step-by-step explanation:

(0,3) and (2,-1)

3-(-1)= 4

0-2= -2

4/-2= -2 so the slope is -2 and we already know the y intercept is 3 because that is when x is 0.

so the equation will y= -2x + 3
