Answer:
There are no true solutions to the equation
Step-by-step explanation:
The equation is
y+1=√-2y-3
Find y
Square both sides
(y+1)^2=(√-2y-3)^2
y^2+2y+1= -2y-3
y^2+2y+1+2y+3=0
y^2+4y+4=0
Solve quadratic equation by factorisation
we have
(y+2)(y+2)=0
y=-2
Check
y+1=√-2y-3
-2+1=√-2(-2)-3
-1=√4-3
-1=√1
-1=1
This is not true
Y = ( x - 3 )² + 4
Vertex of the parabola: ( 3, 4 )
y = - x + b
4 = - 3 + b
b = 7
Equation 2: y = - x + 7
( x - 3 )² + 4 = - x + 7
x² - 6 x + 9 + 4 = - x + 7
x² - 5 x + 6 = 0
x - 2 x - 3 x + 6 = 0
x ( x - 2 ) - 3 ( x - 2 ) = 0
( x - 2 ) ( x - 3 ) = 0
x 1 = 2, x 2 = 3
y 1 = 5, y 2 = 4

Answer:
Step-by-step explanation:
we are given that 1 angle equals 27 and the other two are equal.
180-27=153. and the other two are equal so they each equal 76.5 (153 divided by 2) now since one of the angles is supplementary with angle x, they together must equal 180 so: 180-76.5=x, x=103.5
