Answer:
y = 4
Step-by-step explanation:
2[2y-1]+5=19 (by PEDMAS, distribute parentheses first)
(2)(2y) - (2)(1) + 5 = 19
4y - 2 + 5 = 19
4y +3 = 19 (subtract 3 from both sides)
4y = 19 - 3
4y = 16 (divide both sides by 4)
y = 16/4
y = 4
<span>4x^2-36x/x-9
= 4x(x-9) / (x-9)
if 4x = 0, ⇒ x = 0
x-9 ≠ 0
zero of function is 0.

Answer:
Step-by-step explanation:
3(y + 2) = 14
3y + 6 = 14
3y = 14 - 6
3y = 8
y = 8/3 or 2 2/3
Answer:
-2x-5y+8z+4.5=0
Step-by-step explanation:
Let (x,y,z) be the coordinates of the point lying on the needed plane. This point is equidistant from the points (-3, 5, -4) and (-5, 0, 4), so
I'm going for a range of 0 < x <2<span>π
This is R sin (x-a), although R is 1.
a = </span><span>π/7, so
=> sin (x-(</span><span>π/7)) = -1/(sqrt(2))
=> x = 53</span>π/28, 39<span>π/28</span>
