Answer:

y = -16.9

Step-by-step explanation:

<u>→Add 0.8y to both sides:</u>

-0.8y + 5.49 = -19.86 - 2.3y

5.49 = -19.86 - 1.5y

<u>→Add 19.86 to both sides:</u>

25.35 = -1.5y

<u>→Divide both sides by -1.5:</u>

-16.9 = y

Answer:

\boxed{y =  - 16.9}

Step-by-step explanation:

=  >  - 0.8y + 5.49 =  - 19.86 - 2.3y \\  \\  =  >  - 0.8y + 2.3y + 5.49 =  - 19.86 \\  \\  =  > 1.5y  + 5.49 =  - 19.86 \\  \\  =  > 1.5y =  - 19.86 - 5.49 \\  \\  =  > 1.5y =  - 25.35 \\  \\  =  > y =  -  \frac{25.35}{1.5}  \\  \\  =  > y =  - 16.9

Find the zero of the function f (x) = -2x +2.
Zielflug [23.3K]

Answer:0 = 3x - 21

Step-by-step explanation:

From this given function we can take an  

x

common from its expression

i.e  

x

2

−

6

x

 

=

x

(

x

−

6

)

As we know that the product of two numbers is zero,when either one of them is zero

then in the above expression that we just factorised

the function can be zero when either  

x

=

0

or when  

x

=

6

i.e when  

x

=

0

,  

0

(

0

−

6

)

=

0

 

when  

x

=

6

,  

6

(

6

−

6

)

 

=

6

(

0

)

Finally, our prize of all that math, the zeroes of the function are  

0

and  

6

these numbers are called the zeroes of the function because when you put these values in  

x

the function gives zero.

-8 + 5x - 2 = 20 solve
vaieri [72.5K]

Combining like terms on the left-hand side gives us 5x-10=20. Adding 10 to both sides gives 5x=30, and dividing both sides by 5 gives our answer of \boxed{x=6}.
