Answer:

» <u>Answer</u><u>:</u><u> </u><u>The</u><u> </u><u>third</u><u> </u><u>objective</u>

{ \tt{h(x) =  - 4x + 1}}

• make x the subject:

{ \tt{h(x) - 1 =  - 4x  }} \\  \\ { \tt{x =  \frac{h(x)}{ - 4}  -  \frac{1}{ - 4} }} \\  \\ { \tt{x =  -  \frac{h(x)}{4} +  \frac{1}{4}  }}

• Therefore, f(x):

{ \boxed{ \boxed{ \tt{ \:  \: f(x) =  -  \frac{1}{4}x  +  \frac{1}{4}   \:  \: }}}}

An expression is shown below. Which expression is equivalent to the expression shown?
Vera_Pavlovna [14]

Note: In option A, it should be "+" instead of "(".

Given:

The expression is

-2x(x+y-3)+3(-x+4y)+y(3x+5y-3)

To find:

The equivalent expression.

Solution:

We have,

-2x(x+y-3)+3(-x+4y)+y(3x+5y-3)

Using distributive property, we get

=-2x(x)-2x(y)-2x(-3)+3(-x)+3(4y)+y(3x)+y(5y)+y(-3)

=-2x^2-2xy+6x-3x+12y+3xy+5y^2-3y

On combining like terms, we get

=-2x^2+5y^2+(-2xy+3xy)+(6x-3x)+(12y-3y)

=-2x^2+5y^2+xy+3x+9y

The expression -2x^2+5y^2+xy+3x+9y is equivalent to the given expression.

Therefore, the correct option is A.
