It is in the hundredths place
1 Si los sumandos son del mismo signo, se suman los valores absolutos y al resultado se le pone el signo común. 2 Si los sumandos son de distinto signo, se restan los valores absolutos (al mayor le restamos el menor) y al resultado se le pone el signo del número de mayor valor absoluto.
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
The solution would be x = 0, x = 3
23.1 can be estimated to 23 rounded to 20.
19.24 can be estimated to 19 rounded to 20.
The answer would be 42 which would be rounded to 40.
