jek_recluse [69]

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

1. If the same number is added to the numerator and subtracted from the denominator of 23/12, the resulting fraction is equivale
ICE Princess25 [194]

Answer:

The number is -2

Step-by-step explanation:

step 1

Find the reciprocal of 2/3

Remember that when multiply a number by its reciprocal, the result is 1

so

The reciprocal of 2/3 is 3/2

step 2

Let

x-----> the number added to the numerator and denominator

\frac{23+x}{12-x}=\frac{3}{2}

Solve for x

2(23+x)=3(12-x)\\46+2x=36-3x\\2x+3x=36-46\\5x=-10\\x=-2

step 3

verify

\frac{23+x}{12-x}

substitute x=-2

\frac{23-2}{12+2}

\frac{21}{14}

Simplify

\frac{3}{2} ----> is ok

therefore

The number is -2

Science textbooks are ordered every 10 years math textbooks are ordered every 5 years if new science and math textbooks were ord
Musya8 [376]
10 years, because In 5 years after 2008, 2013 you get new math books 5 more years you get another set of math books-2018, but 2008 plus 10 years you get science books which is also 2018 which is also when you get another set of math books. So the next year you get math books and science books shipped the same year is 2018. 2018-2008=10 so 10 years pass
