The function of x is \bold{\frac{-1x}{2}}.

<u>SOLUTION:</u>  

Given that, we have to write a linear function f with function of (-4) =2 and function of 6=(−3).

Now, let the linear function be \text{function of x}=a x+b

Then, function of -4 = a(-4)+b \rightarrow 2=-4 a+b \rightarrow b=2+4a \rightarrow (1)

And, function of 6 = a(6)+b \rightarrow-3=6 a+b \rightarrow b=-3-6a \rightarrow (2)

On equating (1) and (2) to find the value of a,

2+4a=-3-6a

On grouping the common terms,

4a+6a=-3-2 \rightarrow 10a=-5 \rightarrow a=\frac{-5}{10}

\Rightarrow a=\frac{-1}{2} \rightarrow (3)

On substituting the value of (3) in (1) we get,

b=2+4a \rightarrow b=2+4\times\frac{-1}{2} \rightarrow b=2+\frac{-4}{2} \rightarrow b=2+(-2)

\Rightarrow b=0

So, the function of x = \frac{-1x}{2}+0

A gift has the dimensions of 50 cm x 35 cm x 5 cm. You have wrapping paper with
sleet_krkn [62]

Answer:

Yes, there is enough wrapping paper

The area of the wrapping paper is greater than area of the gift

Step-by-step explanation:

What to do is to check the area of the wrapping paper and the gift if equal.

Looking at the dimensions of the gift, it is a cuboid

Area of a cuboid = 2(lb + lh + bh)

where l, b and h are 50, 35,5 respectively

= 2(250 + 175 + 1750)

= 4350 cm^2

The area of the wrapping paper is just the product of its side = 75 * 60 = 4500 cm^2

We can see clearly that the area of the wrapping paper is greater than area of the gift.

so we can conclude that it is enough to wrap the gift
